PREDICTIVE HANDOFF AND WIRELESS ASSOCIATION IN A NETWORK
According to one configuration, a first wireless access point communicates probe request communications to a mobile communication device. The first wireless access point monitors power levels associated with probe response communications from the mobile communication device. Via the monitored power levels, the communication management resource quantifies motion of the mobile communication device with respect to the first wireless access point and a corresponding region of wireless coverage provided by the first wireless access point. The communication management resource selects amongst multiple neighboring wireless access points in which to handoff the mobile communication device based on a prediction of which of the multiple wireless access points will provide a best chance of successfully receiving a handoff of a mobile communication device and corresponding wireless communication link from the first wireless access point.

Adjusting attribute of remote unit based on information regarding interfering device to cause subscriber unit to connect to and/or camp on remote unit rather than interfering device
A remote unit of a distributed antenna system (DAS) includes: interface device configured to interface with an upstream component of the DAS; and receiver communicatively coupled to an antenna and configured to receive signals from at least one subscriber unit within a coverage area of the DAS. The receiver temporarily reconfigured to receive interference signals from an interfering device outside of the coverage area of the DAS. The interference signals cause a subscriber unit to establish a connection with the interfering device rather than the remote unit of the DAS. The remote unit configured to derive information about the interfering device from the interference signals. The remote unit configured to adjust at least one attribute to cause the subscriber unit to establish connection with the remote unit rather than the interfering device.

Ultra-low power data transmission method and apparatus
An ultra-low power data transmission method and apparatus are disclosed. An ultra-low power data transmission method to be performed by a user terminal of an ultra-low power data transmission system includes performing channel coding on a payload included in a transmission packet; interleaving a payload obtained through the channel coding, spreading the interleaved payload using a gold code and an orthogonal variable spreading factor (OVSF), combining a synchronization header spread using the gold code and the OVSF with the spread payload, and modulating a transmission packet in which the payload and the synchronization header are combined.

Random Access Power Control
A wireless device transmits a first preamble via a first sub-band. The wireless device determines to perform a first preamble retransmission based on receiving no response to the first preamble. The wireless device selects, for the first preamble retransmission, a second sub-band. Based on the second sub-band being different from the first sub-band, the wireless device determines that a transmission power of the first preamble retransmission may be based on a same value of a power ramping counter used for transmitting the first preamble. The wireless device transmits, based on the transmission power, a second preamble for the first preamble retransmission via the second sub-band.
METHOD AND APPARATUS FOR PROVIDING ENHANCED REFERENCE SIGNAL RECEIVED POWER ESTIMATION
A method and an apparatus for providing reference signal received power (RSRP) are disclosed herein. According to one embodiment, a signal is received in a modem. Signal elements at reference signal (RS) locations are extracted from the received signal. The signal elements are descrambled to remove a RS sequence. A linear average of the descrambled signal elements is performed to form virtual reference signal (VRS) elements. The RSRP is estimated from the VRS elements.

Channel State Information Feedback for Multiple Transmission Reception Points
Configuration parameters, of channel state information (CSI) resources for a first transmission reception point (TRP) and a second TRP of a cell, are received. One or more media access control control elements (MAC CEs) are received. The MAC CEs indicate a first semi persistent CSI report for the first TRP. The MAC CEs indicate a second semi persistent CSI report for the second TRP. First reference signal received power (RSRP) values, for the first semi persistent CSI report, are determined based on the plurality of CSI resources. Second RSRP values, for the second semi persistent CSI report, are determined based on the CSI resources. A codeword, comprising the first RSRP values and the second RSRP values, is created. The codeword is transmitted, based on the first semi persistent CSI report and the second semi persistent CSI report, via a physical uplink control channel resource.
