CONFIGURED UL WITH REPETITION

Abstract

A method for enabling Configured Uplink with repetition in a wireless communications system. In examples discussed herein, a wireless device (e.g., a user equipment) receives a configured number of repetitions from a base station (e.g., an eNB). Accordingly, the wireless device repeats a Transport Block (TB) corresponding to a Physical Uplink Shared Channel (PUSCH) transmission across an equal number of consecutive PUSCHs as the configured number of repetitions. As a result, the wireless device can support Configured Uplink with repletion, for example, when the repetition is configured for New Radio Unlicensed band (NR-U) Configured Uplink.

Some examples of a communication device include, but are not limited to: mobile phone, smart phone, sensor device, meter, vehicle, household appliance, medical appliance, media player, camera, or any type of consumer electronic, for instance, but not limited to, a television, radio, lighting arrangement, tablet computer, laptop, or Personal Computer (PC). The communication device may be a portable, hand-held, computer-comprised, or vehicle-mounted mobile device, enabled to communicate voice and/or data via a wireless or wireline connection.

[0110] Wireless Communication Device: One type of communication device is a wireless communication device, which may be any type of wireless device that has access to (i.e., is served by) a wireless network (e.g., a cellular network). Some examples of a wireless communication device include, but are not limited to: a User Equipment device (UE) in a 3GPP network, a Machine Type Communication (MTC) device, and an Internet of Things (IoT) device.

The wireless communication device may be a portable, hand-held, computer-comprised, or vehicle-mounted mobile device, enabled to communicate voice and/or data via a wireless connection.

[0111] Network Node: As used herein, a “network node” is any node that is either part of the radio access network or the core network of a cellular communications network/system.

[0112] Note that the description given herein focuses on a 3GPP cellular communications system and, as such, 3GPP terminology or terminology similar to 3GPP terminology is oftentimes used. However, the concepts disclosed herein are not limited to a 3GPP system.

[0113] Note that, in the description herein, reference may be made to the term “cell”; however, particularly with respect to 5G NR concepts, beams may be used instead of cells and, as such, it is important to note that the concepts described herein are equally applicable to both cells and beams.

[0114] There currently exist a certain challenge(s). The Configured Uplink with repetition mechanism as described above may not be used as is for NR operation in New Radio Unlicensed Band (NR-U), especially after the extension of the Configured Uplink time resources to a set of slots in every time period instead of one slot every time period. New rules should be defined to specify UE behavior when repetition is configured for NR-U Configured Uplink.

[0115] Certain aspects and embodiments of the present disclosure may provide solutions to the aforementioned or other challenges. Embodiments of a method for enabling NR-U Configured Uplink with repetition are provided. More specifically, embodiments disclosed herein include various embodiments for repeating a transport block (TB) corresponding to a transmitted Physical Uplink Shared Channel (PUSCH) in accordance to a configured maximum number of repetitions and a configured redundancy version (RV) sequence.

[0116] There are, proposed herein, various embodiments which address one or more of the issues disclosed herein. In one aspect, a method performed by a wireless device for enabling New Radio Unlicensed spectrum (NR-U) Configured Uplink with repetition is provided. As illustrated in FIG. 5 (where optional steps are represented by dashed lines/boxes), the method includes receiving (500) a configured maximum number of repetitions (repK) and a configured RV sequence, e.g., via a UE-specific signaling (e.g., UE-specific Radio Resource Control (RRC) signaling). The method also includes repeating (502) a TB corresponding to a PUSCH transmission in accordance to the configured repK and the configured RV sequence.

[0117] Certain embodiments may provide one or more of the following technical advantage(s). The method discussed herein sets new rules that specify UE behavior when repetition is configured for NR-U configured UL. These new rules may help eliminate ambiguity with respect to Hybrid Automatic Repeat Request (HARQ) process and the repetition index.

[0118] FIG. 6 illustrates one example of a cellular communications system 600 in which embodiments of the present disclosure may be implemented. In the embodiments described herein, the cellular communications system 600 is a 5G system (5GS) including a NR RAN or LTE RAN (i.e., E-UTRA RAN). In this example, the RAN includes base stations 602-1 and 602-2, which in 5G NR are referred to as gNBs (e.g., LTE RAN nodes connected to 5GC, which are referred to as gn-eNBs), controlling corresponding (macro) cells 604-1 and 604-2. The base stations 602-1 and 602-2 are generally referred to herein collectively as base stations 602 and individually as base station 602. Likewise, the (macro) cells 604-1 and 604-2 are generally referred to herein collectively as (macro) cells 604 and individually as (macro) cell 604. The RAN may also include a number of low power nodes 606-1 through 606-4 controlling corresponding small cells 608-1 through 608-4. The low power nodes 606-1 through 606-4 can be small base stations (such as pico or femto base stations) or Remote Radio Heads (RRHs), or the like. Notably, while not illustrated, one or more of the small cells 608-1 through 608-4 may alternatively be provided by the base stations 602. The low power nodes 606-1 through 606-4 are generally referred to herein collectively as low power nodes 606 and individually as low power node 606. Likewise, the small cells 608-1 through 608-4 are generally referred to herein collectively as small cells 608 and individually as small cell 608. The cellular communications system 600 also includes a core network 610, which in the 5GS is referred to as the 5G core (5GC). The base stations 602 (and optionally the low power nodes 606) are connected to the core network 610.

[0119] The base stations 602 and the low power nodes 606 provide service to wireless communication devices 612-1 through 612-5 in the corresponding cells 604 and 608. The wireless communication devices 612-1 through 612-5 are generally referred to herein collectively as wireless communication devices 612 and individually as wireless communication device 612. In the following description, the wireless communication devices 612 are oftentimes UEs, but the present disclosure is not limited thereto.

[0120] FIG. 7 is a flowchart of an exemplary method performed by a wireless device for enabling Configured Uplink with repetition according to an embodiment of the present disclosure. In this regard, a wireless device (e.g., a UE) receives a configured number of repetitions (step 700). Accordingly, the wireless device repeats a TB corresponding to a PUSCH transmission across an equal number of consecutive PUSCHs as the configured number of repetitions (step 702). Notably, all of the consecutive PUSCHs have an identical length and fall within one or more Configured Grant-PUSCH (CG-PUSCH) transmission periods.

[0121] FIG. 8 is a flowchart of an exemplary method performed by a base station for enabling Configured Uplink with repetition. In this regard, a base station (e.g., an eNB) provides a configured number of repetitions to a wireless device (step 800). Accordingly, the base station receives, from the wireless device, repetition of a TB corresponding to a PUSCH transmission across an equal number of consecutive PUSCHs as the configured number of repetitions (step 802). Notably, all of the consecutive PUSCHs have an identical length and fall within one or more CG-PUSCH transmission periods.

[0122] Repetition of TB is not precluded in NR-U. In NR Rel-15, repetition of a TB is supported only across slots, and the same time-domain resource is used for K repetitions for a TB including the initial transmission. Additionally, repetition is only allowed within the same period of UL transmission with configured grant and should not cross to the next transmission period.

[0123] For NR-U, the above-mentioned constraints should be relaxed given that the RV is indicated in every CG-PUSCH, thus helping to eliminate ambiguity at the gNB side with respect to the HARQ process and the repetition index.

[0124] If repetition is configured, a UE should repeat a transmitted PUSCH according to a configured maximum number of repetitions and follow the RV sequence configured by UE-specific RRC signaling. Several exemplary embodiments are discussed below.

[0125] In a first embodiment, an initial transmission of a TB is allowed to be configured to start at any occasion in the CG-PUSCH window followed by K repetitions according to the configured RV sequence. The initial transmission of a TB may be configured to always correspond to RV 0. For instance, in regard to the PUSCH transmission of FIGS. 7 and 8, an initial transmission of the TB corresponding to the PUSCH transmission is allowed to be configured to start at any occasion in the CG-PUSCH window followed by K repetitions (i.e., the number of repetitions configured in steps 700 and 800 of FIGS. 7 and 8, respectively) according to the configured RV sequence.

[0126] In a second embodiment, the UE may repeat the TB across equal numbers of consecutive PUSCHs, as in step 702, based on one or more of the following options. For both Type 1 and Type 2 PUSCH transmissions with a configured grant, when a UE is configured with repK>1, at least one of the following alternatives may be applied: [0127] Option 1: the UE shall repeat the TB across the repK consecutive slots within one CG-PUSCH window (e.g., the set of allocated slots for CG transmissions) with the same symbol allocation in each slot. [0128] Option 2: the UE shall repeat the TB across the repK consecutive slots within one CG-PUSCH window and across consecutive CG-PUSCH windows with the same symbol allocation in each slot. [0129] Option 3: the UE shall repeat the TB across the repK consecutive PUSCHs within the CG-PUSCH windows. All PUSCH are of the same length. The consecutive PUSCH are limited with one CG-PUSCH. Alternatively, the consecutive PUSCH can cross to the next CG-PUSCH transmission period. [0130] Option 4: the UE shall repeat the TB across the repK non-consecutive PUSCHs within the CG-PUSCH windows. All PUSCH are of the same length. The two neighboring PUSCH occasions are separated by a time offset. The offset may be configured by the gNB or in the ConfiguredGrantConfig. As for which offset configuration is applied, it may be hard coded in the spec. [0131] Alternatively, it may be configured for a UE by the gNB via signaling such as system information, dedicated RRC signaling, MAC CE or DCI. As another alternative, the option may be configured per ConfiguredGrantConfig. In this regard, a corresponding parameter indicating the Option may be included in ConfiguredGrantConfig.

[0132] In one aspect of this embodiment, repetition is allowed to cross to the next transmission period. Alternatively, the repetition is only allowed within the same period of UL transmission with configured grant and should not cross to the next transmission period. That is, the repetitions shall be terminated after at the last transmission occasion among the K repetitions within the period.

[0133] In a third embodiment, for any RV sequence, the repetitions shall be terminated after transmitting K repetitions, or when a UL grant for scheduling the same TB is received within the period P, or when an explicit ACK for the same TB is received via DFI, whichever is reached first. As such, the wireless device can ensure that the TB is repeated across an equal number of consecutive PUSCHs as the configured number of repetitions as in step 702.

[0134] In a fourth embodiment, the NDI value is the same for all the K repetitions. For example, if the first repetition indicates that NDI is equal to 1, the following remaining k−1 repetition indicates the same value. The NDI is toggled only for initial transmission of a transport block. In this regard, the wireless device can ensure that all of the consecutive PUSCHs have an identical length and fall within one or more Configured Grant-PUSCH (CG-PUSCH) transmission periods.

[0135] In a fifth embodiment, the timer (e.g., CGRT) may be started/restarted when a TB is transmitted/retransmitted. If no ACK is received before the timer expires, a UE may assume NACK and perform non-adaptive retransmission. In this regard, the wireless device can determine when to repeat the TB corresponding to the PUSCH transmission, as in step 702.

[0136] For a configured grant in which both the CGRT timer and repetition configurations (e.g., repK and repK-RV) are configured (e.g., present in the ConfiguredGrantConfig), if repetition is configured, the timer is started and restarted for a HARQ process with at least one of the following options: [0137] Option 1: the CGRT timer is immediately started after the first PUSCH repetition transmission and restarted after every subsequent TB repetition transmission. [0138] Option 2: the CGRT timer is not started until the last PUSCH repetition transmission is performed. In this regard, the timer is not started after transmission of the first repK−1 repetition transmissions. [0139] Option 3: the CGRT timer is started immediately after the last PUSCH repetition transmission within an UL transmission period. [0140] Option 4: the CGRT timer is not started until the Nth repetition transmission is performed, where N may be configured by the gNB, the configuration may also be included in the ConfiguredGrantConfig, where N<=repK. In this manner, the timer is not started after transmission of the first N−1 repetition transmissions. As soon as the timer is started, the timer will be restarted after every subsequent TB repetition. [0141] Option 5: the CGRT timer is started after the first repetition transmission and a time period has expired. The time period may be configured by the gNB, and the configuration may also be included in the ConfiguredGrantConfig. As soon as the timer is started, the timer will be restarted after every subsequent TB repetition.

[0142] In a sixth embodiment, for a configured grant in which both the CGRT timer and repetition configurations (e.g., repK and repK-RV) are configured (e.g., present in the ConfiguredGrantConfig), if the CGRT timer is started/restarted after for a TB, the UE may use a next repetition occasion for retransmission of the TB upon expiry of the timer. In this regard, the wireless device can determine when to repeat the TB corresponding to the PUSCH transmission, as in step 702.

[0143] Now, some additional aspects that are applicable to all of the embodiments described above will be described.

[0144] FIG. 9 is a schematic block diagram of a radio access node 900 according to some embodiments of the present disclosure. Optional features are represented by dashed boxes. The radio access node 900 may be, for example, a base station 602 or 606 or a network node that implements all or part of the functionality of the base station 602 or gNB described herein. As illustrated, the radio access node 900 includes a control system 902 that includes one or more processors 904 (e.g., Central Processing Units (CPUs), Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), and/or the like), memory 906, and a network interface 908. The one or more processors 904 are also referred to herein as processing circuitry. In addition, the radio access node 900 may include one or more radio units 910 that each includes one or more transmitters 912 and one or more receivers 914 coupled to one or more antennas 916. The radio units 910 may be referred to or be part of radio interface circuitry. In some embodiments, the radio unit(s) 910 is external to the control system 902 and connected to the control system 902 via, e.g., a wired connection (e.g., an optical cable). However, in some other embodiments, the radio unit(s) 910 and potentially the antenna(s) 916 are integrated together with the control system 902. The one or more processors 904 operate to provide one or more functions of a radio access node 900 as described herein. In some embodiments, the function(s) are implemented in software that is stored, e.g., in the memory 906 and executed by the one or more processors 904.

[0145] FIG. 10 is a schematic block diagram that illustrates a virtualized embodiment of the radio access node 900 according to some embodiments of the present disclosure. This discussion is equally applicable to other types of network nodes. Further, other types of network nodes may have similar virtualized architectures. Again, optional features are represented by dashed boxes.

[0146] As used herein, a “virtualized” radio access node is an implementation of the radio access node 900 in which at least a portion of the functionality of the radio access node 900 is implemented as a virtual component(s) (e.g., via a virtual machine(s) executing on a physical processing node(s) in a network(s)). As illustrated, in this example, the radio access node 900 may include the control system 902 and/or the one or more radio units 910, as described above. The control system 902 may be connected to the radio unit(s) 910 via, for example, an optical cable or the like. The radio access node 900 includes one or more processing nodes 1000 coupled to or included as part of a network(s) 1002. If present, the control system 902 or the radio unit(s) 910 is connected to the processing node(s) 1000 via the network 1002. Each processing node 1000 includes one or more processors 1004 (e.g., CPUs, ASICs, FPGAs, and/or the like), memory 1006, and a network interface 1008.

[0147] In this example, functions 1010 of the radio access node 900 described herein are implemented at the one or more processing nodes 1000 or distributed across the one or more processing nodes 1000 and the control system 902 and/or the radio unit(s) 910 in any desired manner. In some particular embodiments, some or all of the functions 1010 of the radio access node 900 described herein are implemented as virtual components executed by one or more virtual machines implemented in a virtual environment(s) hosted by the processing node(s) 1000. As will be appreciated by one of ordinary skill in the art, additional signaling or communication between the processing node(s) 1000 and the control system 902 is used in order to carry out at least some of the desired functions 1010. Notably, in some embodiments, the control system 902 may not be included, in which case the radio unit(s) 910 communicates directly with the processing node(s) 1000 via an appropriate network interface(s).

[0148] In some embodiments, a computer program including instructions which, when executed by at least one processor, causes the at least one processor to carry out the functionality of the radio access node 900 or a node (e.g., a processing node 1000) implementing one or more of the functions 1010 of the radio access node 900 in a virtual environment according to any of the embodiments described herein is provided. In some embodiments, a carrier comprising the aforementioned computer program product is provided. The carrier is one of an electronic signal, an optical signal, a radio signal, or a computer readable storage medium (e.g., a non-transitory computer readable medium such as memory).

[0149] FIG. 11 is a schematic block diagram of the radio access node 900 according to some other embodiments of the present disclosure. The radio access node 900 includes one or more modules 1100, each of which is implemented in software. The module(s) 1100 provide the functionality of the radio access node 900 described herein. This discussion is equally applicable to the processing node 1000 of FIG. 10 where the modules 1100 may be implemented at one of the processing nodes 1000 or distributed across multiple processing nodes 1000 and/or distributed across the processing node(s) 1000 and the control system 902.

[0150] FIG. 12 is a schematic block diagram of a wireless communication device 1200 according to some embodiments of the present disclosure. As illustrated, the wireless communication device 1200 includes one or more processors 1202 (e.g., CPUs, ASICs, FPGAs, and/or the like), memory 1204, and one or more transceivers 1206 each including one or more transmitters 1208 and one or more receivers 1210 coupled to one or more antennas 1212. The transceiver(s) 1206 includes radio-front end circuitry connected to the antenna(s) 1212 that is configured to condition signals communicated between the antenna(s) 1212 and the processor(s) 1202, as will be appreciated by one of ordinary skill in the art. The processors 1202 are also referred to herein as processing circuitry. The transceivers 1206 are also referred to herein as radio circuitry. In some embodiments, the functionality of the wireless communication device 1200 described above may be fully or partially implemented in software that is, e.g., stored in the memory 1204 and executed by the processor(s) 1202. Note that the wireless communication device 1200 may include additional components not illustrated in FIG. 12 such as, e.g., one or more user interface components (e.g., an input/output interface including a display, buttons, a touch screen, a microphone, a speaker(s), and/or the like and/or any other components for allowing input of information into the wireless communication device 1200 and/or allowing output of information from the wireless communication device 1200), a power supply (e.g., a battery and associated power circuitry), etc.

[0151] In some embodiments, a computer program including instructions which, when executed by at least one processor, causes the at least one processor to carry out the functionality of the wireless communication device 1200 according to any of the embodiments described herein is provided. In some embodiments, a carrier comprising the aforementioned computer program product is provided. The carrier is one of an electronic signal, an optical signal, a radio signal, or a computer readable storage medium (e.g., a non-transitory computer readable medium such as memory).

[0152] FIG. 13 is a schematic block diagram of the wireless communication device 1200 according to some other embodiments of the present disclosure. The wireless communication device 1200 includes one or more modules 1300, each of which is implemented in software. The module(s) 1300 provides the functionality of the wireless communication device 1200 described herein.

[0153] With reference to FIG. 14, in accordance with an embodiment, a communication system includes a telecommunication network 1400, such as a 3GPP-type cellular network, which comprises an access network 1402, such as a RAN, and a core network 1404. The access network 1402 comprises a plurality of base stations 1406A, 1406B, 1406C, such as Node Bs, eNBs, gNBs, or other types of wireless Access Points (APs), each defining a corresponding coverage area 1408A, 1408B, 1408C. Each base station 1406A, 1406B, 1406C is connectable to the core network 1404 over a wired or wireless connection 1410. A first UE 1412 located in coverage area 1408C is configured to wirelessly connect to, or be paged by, the corresponding base station 1406C. A second UE 1414 in coverage area 1408A is wirelessly connectable to the corresponding base station 1406A. While a plurality of UEs 1412, 1414 are illustrated in this example, the disclosed embodiments are equally applicable to a situation where a sole UE is in the coverage area or where a sole UE is connecting to the corresponding base station 1406.

[0154] The telecommunication network 1400 is itself connected to a host computer 1416, which may be embodied in the hardware and/or software of a standalone server, a cloud-implemented server, a distributed server, or as processing resources in a server farm. The host computer 1416 may be under the ownership or control of a service provider, or may be operated by the service provider or on behalf of the service provider. Connections 1418 and 1420 between the telecommunication network 1400 and the host computer 1416 may extend directly from the core network 1404 to the host computer 1416 or may go via an optional intermediate network 1422. The intermediate network 1422 may be one of, or a combination of more than one of, a public, private, or hosted network; the intermediate network 1422, if any, may be a backbone network or the Internet; in particular, the intermediate network 1422 may comprise two or more sub-networks (not shown).

[0155] The communication system of FIG. 14 as a whole enables connectivity between the connected UEs 1412, 1414 and the host computer 1416. The connectivity may be described as an Over-the-Top (OTT) connection 1424. The host computer 1416 and the connected UEs 1412, 1414 are configured to communicate data and/or signaling via the OTT connection 1424, using the access network 1402, the core network 1404, any intermediate network 1422, and possible further infrastructure (not shown) as intermediaries. The OTT connection 1424 may be transparent in the sense that the participating communication devices through which the OTT connection 1424 passes are unaware of routing of uplink and downlink communications. For example, the base station 1406 may not or need not be informed about the past routing of an incoming downlink communication with data originating from the host computer 1416 to be forwarded (e.g., handed over) to a connected UE 1412. Similarly, the base station 1406 need not be aware of the future routing of an outgoing uplink communication originating from the UE 1412 towards the host computer 1416.

[0156] Example implementations, in accordance with an embodiment, of the UE, base station, and host computer discussed in the preceding paragraphs will now be described with reference to FIG. 15. In a communication system 1500, a host computer 1502 comprises hardware 1504 including a communication interface 1506 configured to set up and maintain a wired or wireless connection with an interface of a different communication device of the communication system 1500. The host computer 1502 further comprises processing circuitry 1508, which may have storage and/or processing capabilities. In particular, the processing circuitry 1508 may comprise one or more programmable processors, ASICs, FPGAs, or combinations of these (not shown) adapted to execute instructions. The host computer 1502 further comprises software 1510, which is stored in or accessible by the host computer 1502 and executable by the processing circuitry 1508. The software 1510 includes a host application 1512. The host application 1512 may be operable to provide a service to a remote user, such as a UE 1514 connecting via an OTT connection 1516 terminating at the UE 1514 and the host computer 1502. In providing the service to the remote user, the host application 1512 may provide user data which is transmitted using the OTT connection 1516.

[0157] The communication system 1500 further includes a base station 1518 provided in a telecommunication system and comprising hardware 1520 enabling it to communicate with the host computer 1502 and with the UE 1514. The hardware 1520 may include a communication interface 1522 for setting up and maintaining a wired or wireless connection with an interface of a different communication device of the communication system 1500, as well as a radio interface 1524 for setting up and maintaining at least a wireless connection 1526 with the UE 1514 located in a coverage area (not shown in FIG. 15) served by the base station 1518. The communication interface 1522 may be configured to facilitate a connection 1528 to the host computer 1502. The connection 1528 may be direct or it may pass through a core network (not shown in FIG. 15) of the telecommunication system and/or through one or more intermediate networks outside the telecommunication system. In the embodiment shown, the hardware 1520 of the base station 1518 further includes processing circuitry 1530, which may comprise one or more programmable processors, ASICs, FPGAs, or combinations of these (not shown) adapted to execute instructions. The base station 1518 further has software 1532 stored internally or accessible via an external connection.

[0158] The communication system 1500 further includes the UE 1514 already referred to. The UE's 1514 hardware 1534 may include a radio interface 1536 configured to set up and maintain a wireless connection 1526 with a base station serving a coverage area in which the UE 1514 is currently located. The hardware 1534 of the UE 1514 further includes processing circuitry 1538, which may comprise one or more programmable processors, ASICs, FPGAs, or combinations of these (not shown) adapted to execute instructions. The UE 1514 further comprises software 1540, which is stored in or accessible by the UE 1514 and executable by the processing circuitry 1538. The software 1540 includes a client application 1542. The client application 1542 may be operable to provide a service to a human or non-human user via the UE 1514, with the support of the host computer 1502. In the host computer 1502, the executing host application 1512 may communicate with the executing client application 1542 via the OTT connection 1516 terminating at the UE 1514 and the host computer 1502. In providing the service to the user, the client application 1542 may receive request data from the host application 1512 and provide user data in response to the request data. The OTT connection 1516 may transfer both the request data and the user data. The client application 1542 may interact with the user to generate the user data that it provides.

[0159] It is noted that the host computer 1502, the base station 1518, and the UE 1514 illustrated in FIG. 15 may be similar or identical to the host computer 1416, one of the base stations 1406A, 1406B, 1406C, and one of the UEs 1412, 1414 of FIG. 14, respectively. This is to say, the inner workings of these entities may be as shown in FIG. 15 and independently, the surrounding network topology may be that of FIG. 14.

[0160] In FIG. 15, the OTT connection 1516 has been drawn abstractly to illustrate the communication between the host computer 1502 and the UE 1514 via the base station 1518 without explicit reference to any intermediary devices and the precise routing of messages via these devices. The network infrastructure may determine the routing, which may be configured to hide from the UE 1514 or from the service provider operating the host computer 1502, or both. While the OTT connection 1516 is active, the network infrastructure may further take decisions by which it dynamically changes the routing (e.g., on the basis of load balancing consideration or reconfiguration of the network).

[0161] The wireless connection 1526 between the UE 1514 and the base station 1518 is in accordance with the teachings of the embodiments described throughout this disclosure. One or more of the various embodiments improve the performance of OTT services provided to the UE 1514 using the OTT connection 1516, in which the wireless connection 1526 forms the last segment.

[0162] A measurement procedure may be provided for the purpose of monitoring data rate, latency, and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring the OTT connection 1516 between the host computer 1502 and the UE 1514, in response to variations in the measurement results. The measurement procedure and/or the network functionality for reconfiguring the OTT connection 1516 may be implemented in the software 1510 and the hardware 1504 of the host computer 1502 or in the software 1540 and the hardware 1534 of the UE 1514, or both. In some embodiments, sensors (not shown) may be deployed in or in association with communication devices through which the OTT connection 1516 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which the software 1510, 1540 may compute or estimate the monitored quantities. The reconfiguring of the OTT connection 1516 may include message format, retransmission settings, preferred routing, etc.; the reconfiguring need not affect the base station 1518, and it may be unknown or imperceptible to the base station 1518. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling facilitating the host computer 1502's measurements of throughput, propagation times, latency, and the like. The measurements may be implemented in that the software 1510 and 1540 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using the OTT connection 1516 while it monitors propagation times, errors, etc.

In sub-step 1606 (which may be optional) of step 1602, the UE executes a client application which provides the user data in reaction to the received input data provided by the host computer. In providing the user data, the executed client application may further consider user input received from the user. Regardless of the specific manner in which the user data was provided, the UE initiates, in sub-step 1608 (which may be optional), transmission of the user data to the host computer. In step 1610 of the method, the host computer receives the user data transmitted from the UE, in accordance with the teachings of the embodiments described throughout this disclosure.
