Abstract

According to one configuration, a communication management resource in a wireless network environment records a location of a wireless base station. The communication management resource then defines a region of wireless coverage provided by the wireless base station based on feedback received from the wireless base station. For example, in one arrangement, the user equipment provides performance metrics to the wireless base station. The wireless base station uses the performance metrics to determine boundaries associated with a region of wireless coverage provided by the wireless base station. The wireless base station communicates the boundary information to the communication management resource. Subsequent to identifying the location of the wireless base station and defining the determined region of wireless coverage associated with the wireless base station, the communication management resource then controls allocation of wireless bandwidth in a vicinity of the region of wireless coverage to protect the wireless base station from interference.

DETAILED DESCRIPTION

(10) Priority Access License (PAL) holders buy wireless licenses and reserve the right to use them in corresponding pre-determined geographical areas of operation. If there are PLA operators in the CBRS network, the main objection of SAS (Spectrum Access System) is to protect these PLA holders from the interference generated by other users in the network. However, since PAL holders (such as specific network operators) will provide multiple CBSDs (wireless base stations to serve corresponding user equipment). In one embodiment, each of the CBSDs will create a region to be protected from wireless interference so that a respective service provider is able to user equipment licensed wireless channels without experiencing a high level of wireless interference. This region is called PPA.

(11) To provide so-called PAL protection, in accordance with general embodiments herein, a communication management resource in a wireless network environment tracks/records a location of a corresponding wireless base station. The communication management resource (or other suitable resource such as a wireless base station) then defines a region of wireless coverage provided by the wireless base station based on input received from the wireless base station. For example, in one embodiment, the input (indicating a region of wireless coverage provided by a wireless base station) is generated by the wireless base station and/or user equipment based upon wireless link performance metrics provided by user equipment in communication with the wireless base station. Subsequent to identifying the location of the wireless base station and defining the actual (measured) region of wireless coverage associated with the wireless base station, the communication management resource then controls subsequent allocation of wireless bandwidth in a vicinity of the region of wireless coverage to protect the wireless base station from wireless interference.

(12) In contrast to merely using estimation techniques, embodiments herein include determining regions of wireless coverage first respective wireless base stations based at least in part on feedback from user equipment. Techniques as described herein are advantageous because performance metrics from user equipment and/or wireless base stations provide a basis in which to produce a more accurate depiction of the corresponding region of wireless coverage provided by a respective wireless base station.

(13) Now, more specifically, FIG. 1 is an example diagram illustrating a wireless network environment according to embodiments herein.

(14) As shown in this example embodiment, network environment 100 includes communication management resource 140 (such as a spectrum access system), wireless base station 131, user equipment 121-1, user equipment 121-2, user equipment 121-3, user equipment 121-4, wireless base station 132, user equipment 122-1, user equipment 122-2, user equipment 122-3, and network 190 such as the Internet.

(15) Note that each of the resources (such as wireless base station 131, wireless base station 132, user equipment 121, user equipment 122, communication management resource 140, etc., in network environment 100 can be configured to include appropriate hardware, software, or combination of hardware and software to carry out respective operations as discussed herein.

(16) In one embodiment, the communication management resource 140 is a so-called spectrum access system that allocates wireless channels for use by wireless devices (wireless base stations, user equipment, etc.) in the network environment 100.

(17) As shown, the wireless base station 131 provides user equipment 121 (such as user equipment 121-1, user equipment 121-2, user equipment 121-3, user equipment 121-4) wireless access to the remote network 190 over backhaul 175. For example, in an upstream direction, user equipment 121-1 communicates data over a respective wireless communication link to the wireless base station 131; wireless base station 131 then conveys the data over the backhaul 175 to the network 190. In a downstream direction, the backhaul 175 conveys communications from the network 190 destined to the user equipment 121 over the backhaul 175 through the wireless base station 131 to respective target user equipment.

(18) In a similar manner, the wireless base station 132 provides user equipment 122 (such as user equipment 122-1, user equipment 122-2, user equipment 122-3, etc.) wireless access to the remote network 190 over backhaul 175. For example, in an upstream direction, user equipment 122-1 communicates data over a respective wireless communication link to the wireless base station 132; wireless base station 132 conveys the data over the backhaul 175 to the network 190. In a downstream direction, the backhaul 175 conveys communications from the network 190 destined to the user equipment 121 over the backhaul 175 through the wireless base station 131 to respective target user equipment.

(19) In accordance with further embodiments, the communication management resource 140 records a location of wireless base stations in the network environment 100.

(20) In one embodiment, rather than merely estimating a region of wireless coverage provided by a wireless base station, the communication management resource 140 as described herein implements one or more techniques to more accurately define or determine a respective region of wireless coverage of each wireless base station so that wireless base stations are able to use licensed wireless channels without interference from other wireless users. The accurate definition of a respective region of wireless coverage associated with a first wireless base station as described herein ensures that other wireless base stations in a vicinity of the first wireless base station are able to use wireless channels without interference from the first wireless base station and vice versa.

(21) As further shown, to manage wireless communications in the network environment 100, each of the wireless base stations registers with the communication management resource 140 (such as a spectrum access system). For example, in operation #1, via communications 151-1 from the wireless base station 131, the wireless base station 131 notifies the communication management resource 140 of its identity (unique network address=XXZ2) and current location (i.e., location L1). The location information conveyed in communications 151-1 can be conveyed in any suitable format (such as latitude and longitude if desired).

(22) Further, via communications 152-1 from the wireless base station 132, the wireless base station 132 notifies the communication management resource 140 of its identity (unique network address=XXZ3) and current location (i.e., location L2). The location information conveyed in communications 152-1 can be conveyed in any suitable format (such as latitude and longitude if desired).

(23) As an alternative to receiving the location information from the respective wireless base station, note that such information can be received from any suitable resource having knowledge of a location of the respective wireless base station.

(24) FIG. 2 is an example diagram illustrating channel allocation information and service provider information according to embodiments herein.

(25) As shown in FIG. 2, in response to receiving respective communications 151-1 and 151-2, the communication management resource 140 generates PAL (Priority Access License) service provider information 161-1 (stored in repository 180 in FIG. 1), which maps wireless base stations and corresponding identities to locations and corresponding service providers.

(26) More specifically, as shown, the communication management resource 140 maps the wireless base station 131 having network address=XXZ2 to the location L1 and corresponding service provider #1; the communication management resource 140 maps the wireless base station 132 having network address=XXZ3 to the location L2 and corresponding service provider #1; the communication management resource 140 maps the wireless base station 133 having network address=ABX6 to the location L3 and corresponding service provider #2; and so on.

(27) Accordingly, embodiments herein include recording the location of the wireless base stations based on received location information and, as further discussed below, providing a mapping between the location of the wireless base station and the wireless channels licensed to the wireless base station.

(28) Further in this example embodiment, assume that both service provider #1 and service provider #2 are licensed (pay a fee) to use one or more available wireless channels in network environment 100.

(29) In one embodiment, the available wireless channels assigned for use by the communication management resource 140 include wireless channels available in a CBRS (Citizens Band Radio System) frequency band. In such an instance, the communication management resource 140 allocates wireless channels from a CBRS band such as one or more Priority Access License (PAL) wireless channels, one or more General Authorized Access (GAA) wireless channels to different devices (such as wireless base stations 131, 132, or CBSDs) in network environment 100.

(30) Referring again to FIG. 1, in accordance with further embodiments, the communication management resource 140 receives notification of the service provider identity and corresponding general region (such as via license information 163 in FIG. 1) in which each service provider pays fees for a license to use portions of the available wireless spectrum. Note that the license assignment information 163 can be received from any suitable resource having authority to provide such information to the communication management resource 140.

(31) In addition to generating the PAL service provider information 161-1, the communication management resource 140 also creates channel allocation information 162-1 (stored in repository 180 in FIG. 1). As shown, the PAL service provider information 161-1 indicates a mapping of service providers and corresponding wireless channels licensed for use by the different service providers.

(32) As further discussed herein, the communication management resource 140 ensures that the service providers licensing wireless channels in a respective wireless region (so-called PPA or PAL Protection Area) are free to use such channels in their regions of wireless coverage without interference by other wireless users in the network environment 100.

(33) During or after registration of a respective wireless base station with the communication management resource 140 in operation #1, the communication management resource 140 notifies the respective wireless base station of one or more assigned wireless channels.

(34) For example, in operation #2, via communications 171-1, and in accordance with license assignment information 163, the communication management resource 140 notifies the wireless base station 131 that wireless channels #11 and #12 are assigned for use by the wireless base station 131. Via communications 171-2, and in accordance with license assignment information 163 by the channel allocation information 162-1, the communication management resource 140 notifies the wireless base station 131 that wireless channels #11 and #12 are assigned for use by the wireless base station 132; and so on.

(35) Thus, the allocation management resource 140 grants the wireless base stations use of the licensed wireless channels. The wireless base station communicates with user equipment via use of the granted licensed wireless channels.

(36) In one embodiment, the communication management resource 140 allocates any type of wireless channels such as: one or more Priority Access Lease (PAL) wireless channels, General Authorized Access (GAA) wireless channels, or a combination of both.

(37) In this example embodiment, the multiple wireless channels (#11, and #12) assigned by the communication management resource 140 for use by the wireless base station includes wireless channels available in a CBRS (Citizens Band Radio System) frequency band.

(38) Note that the wireless base stations and corresponding user equipment operated in network environment 100 can be configured to communicate in accordance with any suitable wireless communication protocol. In one embodiment, the user equipment in network environment 100 communicates via the LTE (Long Term Evolution) protocol (5G protocol).

(39) Based on the nature of CBRS channels, note that assignment/use of the SAS-allocated channels (such as PAL wireless channels, GAA wireless channels) can be revoked at any time by communication management resource 140 to enable use of the corresponding bandwidth (such as one or more wireless channels) by a higher priority incumbent user such as the government.

(40) Although the communication management resource 140 has general knowledge of the location of each wireless base station 131, 132, etc., further embodiments herein include communicating with each of the wireless base stations to determine an accurate region of wireless coverage provided by each wireless base station as discussed below.

(41) FIG. 3 is an example diagram illustrating wireless base station collection of data from user equipment according to embodiments herein.

(42) As shown in FIG. 3, via operation #3, the service provider #1 provides each of its wireless base stations (such as wireless base station 321, wireless base station 322, etc.) threshold value information to facilitate accurate determination of a respective region of wireless coverage provided by a corresponding wireless base station.

(43) More specifically, service provider #1 transmits communications 311-1 including threshold value information to wireless base station 131. Service provider #2 transmits communications 311-1 including threshold value information to wireless base station 131. Use of the threshold value information to identify boundaries of a respective wireless base station's region of wireless coverage is further discussed below.

(44) Further in this example embodiment, each of the wireless base stations in network environment 100 receives feedback (such as communications 321, 322, etc.) from respective user equipment. The feedback from the user equipment to the wireless base station can include any suitable information.

(45) For example, in one embodiment, the feedback from respective user equipment is or includes wireless link performance metrics generated by the user equipment. The link performance metrics indicate a quality associated with the respective wireless communication link between the user equipment and wireless base station.

(46) More specifically, in this example embodiment, the user equipment 121-1 transmits communications 321-1 (such as link quality performance metrics produced by user equipment 121-1) to the wireless base station 131; the user equipment 121-2 transmits communications 321-2 (such as link quality performance metrics produced by user equipment 121-2) to the wireless base station 131; the user equipment 121-3 transmits communications 321-3 (such as link quality performance metrics produced by 121-3) to the wireless base station 131; the user equipment 121-4 transmits communications 321-4 (such as link quality performance metrics produced by user equipment 121-4) to the wireless base station 131, and so on.

(47) Further, the user equipment 122-1 transmits communications 322-1 (such as link quality performance metrics produced by user equipment 122-1) to the wireless base station 132; the user equipment 122-2 transmits communications 322-2 (such as link quality performance metrics produced by user equipment 122-2) to the wireless base station 132; the user equipment 122-3 transmits communications 322-3 (such as link quality performance metrics produced by user equipment 122-3) to the wireless base station 132; and so on.

(48) In one embodiment, the feedback in respective communications 321, 322 from each respective user equipment includes one or more metrics such as a CQI (Channel Quality Indicator) value, RSRP (Reference Signal Received Power) value, RSRQ (Reference Signal Received Quality) value, RSSI (Received Signal Strength Indicator) value.

(49) The CQI (Channel Quality Indicator) value received from respective user equipment indicates a corresponding quality of the wireless communication link between the respective user equipment sending the CQI value and the wireless base station.

(50) The RSRP (Reference Signal Received Power) value received from respective user equipment indicates is a measure of signal level and quality for modern LTE networks. In general, RSRP is a RSSI-type (received Signal Strength Indicator) of measurement, which indicates the power of the LTE Reference Signals spread over the full bandwidth and narrowband.

(51) The RSRQ (Reference Signal Received Quality) value received from respective user equipment indicates a quality of a received reference signal. RSRQ measurement and calculation is based on RSRP and RSSI. RSRP determines signal quality and RSSI determines co-channel interference and noise.

(52) FIG. 4 is an example diagrams illustrating analysis of data and generation of interference scores for each of the different user equipment according to embodiments herein.

(53) Via operation #5 in FIG. 4, each of the wireless base stations records feedback received from respective user equipment as well as other information (such as a MCS, TBS, user equipment buffer size, average data flow rate of wireless communications between the wireless base station and the user equipment, etc.) associated with the respective user equipment. Wireless base station 131 or other suitable resource records data 431-1. Wireless base station 132 records data 432-1. The MCS value (MCS) is a rough indicator (metric) of wireless bandwidth capability between the user equipment and wireless base station. The TBS value represents a Transport Block Size associated with wireless communications.

(80) The wireless base station 132 produces record 532-2 to include feedback generated by user equipment 122-2 such as CQI (Channel Quality Indicator) value, RSRP (Reference Signal Received Power) value, RSRQ (Reference Signal Received Quality) value, RSSI (Received Signal Strength Indicator) value.

(81) In addition to storing such feedback (such as link quality metrics) from user equipment 122-2, the wireless base station 132 produces the record 532-2 to include additional information such as MCS, TBS, user equipment buffer size, average data flow rate, etc., associated with the user equipment 122-2. As previously discussed, the MCS value (MCS) is a rough indicator (metric) of wireless bandwidth capability between the user equipment and wireless base station. The TBS value is a metric representing a Transport Block Size associated with wireless communications between the user equipment and the wireless base station 132.

(82) Via one or more of the settings associated with user equipment data stored in record 532-2, the wireless base station 132 (or other suitable processing hardware resource) generates a wireless interference score of 76 (a fairly high interference level) associated with the user equipment 122-2 and respective use of a licensed wireless channel allocated by the communication management resource 140.

(83) The wireless base station 132 produces record 532-3 to include feedback (link quality metrics) generated by user equipment 122-3 such as CQI (Channel Quality Indicator) value, RSRP (Reference Signal Received Power) value, RSRQ (Reference Signal Received Quality) value, RSSI (Received Signal Strength Indicator) value.

(84) In addition to storing such feedback from user equipment 122-3, the wireless base station 132 produces the record 532-3 to include additional information such as MCS, TBS, user equipment buffer size, average data flow rate, etc., associated with the user equipment 122-3. As previously discussed, the MCS value (MCS) is a rough indicator (metric) of wireless bandwidth capability between the user equipment and wireless base station. The TBS value is a metric representing a Transport Block Size associated with wireless communications between the user equipment and the wireless base station 132.

(85) Via one or more of the settings associated with user equipment data stored in record 532-3, the wireless base station 132 (or other suitable processing hardware resource) generates a wireless interference score of 31 (a fairly low interference level) associated with the user equipment 122-3 and respective use of a licensed wireless channel allocated by the communication management resource 140.

(86) As previously discussed, note that further embodiments herein include assigning either a high interference level or a low interference level to the user equipment instead of a normalized number between 0 and 100.

(87) For example, in accordance with further embodiments, based on the threshold information provided by a respective service provider, the wireless base station or other suitable resource can be configured to assign respective user equipment a high interference score if the corresponding RSRP from the user equipment is higher than a predetermined threshold (such as previously provided by the service provider #1), and if the RSRQ value provided by the user equipment is lower than a pre-determined threshold, AND average throughput, CQI, and TBS for the user equipment are lower than a pre-determined threshold, AND average UE data buffer size is greater than a pre-defined threshold.

(88) In yet further embodiments, the wireless base station or other suitable resource assigns user equipment a low interference score if the RSRP value from the user equipment is equal or lower than a predetermined threshold, and if the RSRQ value from the user equipment is equal or higher than a pre-determined threshold, AND average throughput, CQI, and TBS are near average or higher than a pre-determined threshold, AND average UE data buffer size is greater than a pre-defined threshold.

(89) Based on such embodiments, as shown in FIG. 5, the interference score (87) assigned to user equipment 121-1 indicates a high level of interference; the interference score (7) assigned to user equipment 121-2 indicates a low level of interference; the interference score (12) assigned to user equipment 121-3 indicates a low level of interference; the interference score (95) assigned to user equipment 121-4 indicates a high level of interference.

(90) The interference score (23) assigned to user equipment 122-1 indicates a low level of interference; the interference score (76) assigned to user equipment 122-2 indicates a high level of interference; the interference score (31) assigned to user equipment 122-3 indicates a low level of interference.

(91) FIG. 6 is an example diagram illustrating determination of a region of wireless coverage for each of multiple wireless base stations and reporting of same to a communication management resource according to embodiments herein.

(92) As previously discussed, certain user equipment in network environment 100 experiences high levels of interference. Because such devices are entitled to protected use of the licensed wireless channels (such as #11 and #12), the wireless base station or other suitable resource initiates a respective test to determine the actual region of wireless coverage associated with a respective wireless base station.

(93) For example, in operation #7, each wireless base station (such as CBSD) calculates the number of high interference user equipment and low interference user equipment supported by the wireless base station.

(94) For user equipment experiencing a high amount of interference (such as user equipment 121-1, 121-4, and user equipment 122-2), the respective wireless base station calculates or estimates the distance based on any suitable distance measurement test such as via sounding reference signals reported by the respective user equipment 121-1, 121-4, and 122-2 experiencing high interference.

(95) In one embodiment, a Sounding Reference Signal (SRS) is a reference signal transmitted by the user equipment in the uplink direction which is used by the wireless base station 131 (such as an eNodeB) to estimate the uplink channel quality over a wider bandwidth. The wireless base station 131 (such as eNodeB) may use this information for uplink frequency selective scheduling.

(96) As an alternative to use of Sounding Reference Signal to determine distance metrics, any other technique of determining a location (such as based on Global Position System information) of the user equipment with respect to the wireless base station can be used as well to determine the region of wireless coverage.

(97) More specifically, the communication management resource 140 has knowledge and control of other communication devices in network environment 100 operating in the CBRS band. For any user equipment (such as user equipment 121-1, 121-4, and 122-2) identified as experiencing high interference levels in the allocated wireless channels #11 and #12, it is assumed that communication devices (such as wireless base stations, user equipment, etc., associated with a service provider #3) in close proximity to the region of wireless coverage 631 and 632 cause interference to service provider #1 and corresponding communication devices assigned use of wireless channels #11 and #12.

(98) To determine a region of wireless coverage with respect to location L1, via communications 321-1 between the wireless base station 131 and the user equipment 121-1, the wireless base station 131 detects a distance between the wireless base station 131 and the user equipment 121-1; via communications 321-4 between the wireless base station 131 and the user equipment 121-4, the wireless base station 131 detects a distance between the wireless base station 131 and the user equipment 121-4; via communications 322-2 between the wireless base station 132 and the user equipment 122-2, the wireless base station 132 (or other suitable resource) detects a distance between the wireless base station 132 and the user equipment 122-2.

(99) In one embodiment, the detected distance represents a radius (or adjusted radius) of wireless coverage with respect to the corresponding wireless base station. The radius is used to indicate the region of wireless coverage associated with each wireless base station.

(100) In accordance with further embodiments, the wireless base station 131 can be configured to add a delta value (buffer value) to the calculated path loss and report the distance value (or adjusted distance value, radius #1) associated with the region of wireless coverage 631 to the communication management resource 140 (such as a spectrum access system). In a similar manner as previously discussed, the wireless base station 132 can be configured to add a delta value (buffer value) to the calculated path loss and report the distance value (or adjusted distance value) associated with the region of wireless coverage 632 to the communication management resource 140 (such as a spectrum access system). In other words, the calculated distance metric (radius) can be adjusted to a larger value to define the region of wireless coverage to reduce a possibility of interference.

(101) Via communications 641, the wireless base station 131 notifies the communication management resource 140 of the actual detected region of wireless coverage 631 associated with the wireless base station 131 and corresponding user equipment.

(102) In response to receiving communications 641 such as information indicating the metes and bounds associated with region of wireless coverage 631 as determined by the wireless base station 131 (or other suitable resource), the communication management resource 140 updates the PAL service provider information 161-2 as shown in FIG. 7 to indicate the accurately generated region of wireless coverage 631 (such as radius #1 with respect to the location L1) associated with the wireless base station 131.

(103) Via communications 642, the wireless base station 132 notifies the communication management resource 140 of the actual region of wireless coverage 632 (such as radius #2 with respect to the location L2) associated with the wireless base station 132.

(104) In response to receiving communications 642 such as information indicating the metes and bounds associated with region of wireless coverage 632 as determined by the wireless base station 132 or other suitable resource, the communication management resource 140 updates the PAL service provider information 161-2 in FIG. 7 to indicate the region of wireless coverage 632 (such as radius #2 with respect to location L2) associated with the wireless base station 132.

(105) FIG. 7 is an example diagram illustrating updated wireless base station data and corresponding regions of wireless coverage based on feedback from the wireless base stations according to embodiments herein.

(106) As further shown in FIG. 7, and as previously discussed, the communication management resource 140 records the determined/updated region of wireless coverage associated with each wireless base station. For example, the communication management resource 140 updates the PAL service provider information 161-2 to indicate the actual region of wireless coverage 631 (such as radius #1 with respect to location L1) and the actual region of wireless coverage 632 (such as radius #2 with respect to location L2).

(107) Referring again to FIG. 6, in operation #8 the communication management resource 140 receives notification of the regions of wireless coverage as well as that the user equipment 121-1, 121-4, and 122-2 experiences high amounts of interference. Thus, the communication management resource 140 is aware that it needs to lower the power levels of any 3rd party communication devices operated in a vicinity of the calculated region of wireless coverage 631 and 632 to prevent interference to corresponding licensed users/service provider #1.

(108) In other words, as further discussed below, because the communication management resource 140 is now aware of the actual regions of wireless coverage 631 and 632 associated with the wireless base stations 131 and 132, the communication management resource 140 prevents granting of or power levels associated with wireless channels at or around the wireless frequency associated with wireless channel #11 and #12 in a vicinity of the regions of wireless coverage 631 and 632. If needed, in operation #9, the communication management resource 140 can be configured to lower power levels of the nearby communication devices (such as wireless base station 621 and wireless base station 622 or corresponding user equipment) causing the interference to the user equipment 121-1, user equipment 121-4, and user equipment 122-2 protected by a corresponding PAL license.

(109) As previously discussed, generation of the boundaries associated with regions of wireless coverage as described herein provides a more accurate geographical region (zone) in which corresponding PAL entities (such as wireless base station 131, user equipment 121, wireless base station 132, user equipment 122) are entitled to protection against wireless interference by other wireless users.

(110) Thus, subsequent to defining the location and respective region of wireless coverage associated with each wireless base station, in operation #9, the communication management resource then controls allocation of wireless bandwidth (such as licensed PAL wireless channels or unlicensed GAA wireless channels) such as to wireless base station 621 at location L6, wireless base station 622 at location L5, etc., in a vicinity of the region of wireless coverage to prevent interference with wireless channels used by wireless base station 131, wireless base station 132, etc. This controlled allocation of bandwidth by the communication management resource 140 in the vicinity of the regions of wireless coverage 631 and 632 provided by the wireless base station protects use of wireless channels licensed to a respective service provider operating the wireless base stations 131 and 132.

(111) FIG. 8 is an example block diagram of a computer system for implementing any of the operations as previously discussed according to embodiments herein.

(112) Any of the resources (such as communication management resource 140, wireless base station 131, user equipment 121-1, user equipment 121-2, etc., wireless base station 132, user equipment 122-1, user equipment 122-2, etc.) as discussed herein can be configured to include computer processor hardware and/or corresponding executable instructions to carry out the different operations as discussed herein.

(113) As shown, computer system 850 of the present example includes an interconnect 811 that couples computer readable storage media 812 such as a non-transitory type of media (which can be any suitable type of hardware storage medium in which digital information can be stored and retrieved), a processor 813 (computer processor hardware), I/O interface 814, and a communications interface 817.

(114) I/O interface(s) 814 supports connectivity to repository 880 and input resource 892.

(115) Computer readable storage medium 812 can be any hardware storage device such as memory, optical storage, hard drive, floppy disk, etc. In one embodiment, the computer readable storage medium 812 stores instructions and/or data.

(116) As shown, computer readable storage media 812 can be encoded with communication management application 140-1 (e.g., including instructions) to carry out any of the operations as discussed herein.

(117) During operation of one embodiment, processor 813 accesses computer readable storage media 812 via the use of interconnect 811 in order to launch, run, execute, interpret or otherwise perform the instructions in management application 140-1 stored on computer readable storage medium 812. Execution of the communication management application 140-1 produces communication management process 140-2 to carry out any of the operations and/or processes as discussed herein.

(118) Those skilled in the art will understand that the computer system 850 can include other processes and/or software and hardware components, such as an operating system that controls allocation and use of hardware resources to execute communication management application 140-1.

(119) In accordance with different embodiments, note that computer system may reside in any of various types of devices, including, but not limited to, a mobile computer, a personal computer system, a wireless device, a wireless access point, a base station, phone device, desktop computer, laptop, notebook, netbook computer, mainframe computer system, handheld computer, workstation, network computer, application server, storage device, a consumer electronics device such as a camera, camcorder, set top box, mobile device, video game console, handheld video game device, a peripheral device such as a switch, modem, router, set-top box, content management device, handheld remote control device, any type of computing or electronic device, etc. The computer system 850 may reside at any location or can be included in any suitable resource in any network environment to implement functionality as discussed herein.

(120) Functionality supported by the different resources will now be discussed via flowcharts in FIGS. 9-10. Note that the steps in the flowcharts below can be executed in any suitable order.

(122) In processing operation 910, the communication management resource 140 tracks (records) a location L1 of wireless base station 131 in the network environment 100.

(123) In processing operation 920, the communication management resource 140 defines a region of wireless coverage 631 provided by the wireless base station 131 based on feedback received from the wireless base station 631.

(124) In processing operation 930, the communication management resource 140 controls allocation of wireless bandwidth (one or more wireless channels) in a vicinity of the region of wireless coverage 631. The controlled allocation protects use of wireless channels (such as wireless channels #11 and #12) licensed to the wireless base station 131 (service provider #1).

(125) FIG. 10 is a flowchart 1000 illustrating an example method according to embodiments. Note that there will be some overlap with respect to concepts as discussed above.

(126) In processing operation 1010, the wireless base station 121 monitors user equipment 121-1, 121-2, 121-3, 121-4 (collectively, user equipment 121) in communication with the wireless base station 131.

(127) In processing operation 1020, the wireless base station 131 receives feedback (such as via respective communications 321-1, 321-2, 321-3, 321-4) from the respective user equipment 121. In one embodiment, the feedback (communications) indicates link quality between the user equipment 121 and the wireless base station 131.

(128) In processing operation 1030, the communication management resource 140 defines a region of wireless coverage 631 with respect to location L1 provided by the wireless base station 131 based on the feedback received from the user equipment.

(129) In processing operation 1040, the communication management resource 140 controls allocation of wireless bandwidth (such as one or more wireless PAL or GAA channels) in a vicinity (such as region of wireless coverage 651 and region of wireless coverage 652) of the region of wireless coverage 631. The controlled allocation in regions nearby region of wireless coverage 631 and region of wireless coverage 632 protects use of wireless channels #11 and #12 licensed to the wireless base station 131.

(130) Note again that techniques herein are well suited to facilitate more accurate determination of a region of wireless coverage provided by a wireless base station and providing appropriate protection against wireless interference to corresponding wireless service providers in such regions. However, it should be noted that embodiments herein are not limited to use in such applications and that the techniques discussed herein are well suited for other applications as well.
