Abstract: This disclosure relates to techniques for dynamically adjusting a number of active receiver chains of a wireless device. Based on communication parameters exchanged with a base station, a device may determine a maximum number of receiver chains needed for data reception during one or more time periods. Such dynamic adjustment may enable power savings.

Abstract: A method includes causing, at a first user equipment (UE), transmission of at least one positioning reference signal (PRS) to a second UE via a sidelink (SL) communication based on first positioning assistance data. The transmission enables the second UE to determine positioning measurements from at least part of the at least one PRS.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a serving cell and a target cell and a processor communicatively coupled to the transceiver. The processor is configured to receive a handover command from the serving cell. The handover command comprises an epoch index and ephemeris information of the target cell. The processor is further configured to determine an epoch time of the target cell based on the epoch index and perform time synchronization with the target cell using the epoch time and the ephemeris information.

Abstract: A user equipment (UE) is configured to provide a power headroom report (PHR) to a network. The UE receives a physical uplink shared channel (PUSCH) configuration from a base station of the wireless network, wherein the PUSCH configuration includes a plurality of beams over which PUSCH repetitions should be transmitted, determines at least one power headroom report (PHR) based on a power control parameter set corresponding to at least one of the plurality of beams or PUSCH repetitions and transmits the at least one PHR to the base station.

Abstract: Systems, apparatuses, and methods for notification support in extended discontinuous reception mode. A base station and UE may configure eDRX communication. An indication may be received during the eDRX communication. The network may cache the indication. The network may modify the DRX configuration. The network may use a wake up signal. In response, the UE may receive the indication while achieving power savings from the eDRX configuration.

Abstract: Disclosed are techniques for differentiating between licensed and unlicensed bands in a common portion of frequency spectrum to facilitate initial access in a fifth generation (5G) new radio (NR) wireless communication system having an NR node. The techniques include an NR generating and UE processing frequency configuration information indicating whether the common portion of frequency spectrum is allocated as a licensed band or an unlicensed band to enable a determination that the frequency spectrum is configured as the licensed band or unlicensed band and thereby facilitate initial access.

Abstract: Performing user equipment (UE) coordination based beam management may include determining resources for measuring beams and reporting measured beam information. The resources may be configured for a first user equipment (UE) of a plurality of coordinated UEs. The determined resources may be transmitted to the first UE via radio resource control (RRC) or medium access control-control element (MAC CE). Measured beam information received from the first UE for configuring beam sharing between multiple UEs of the plurality of coordinated UEs may be decoded.

Abstract: To support layer 1 (L1) and layer 2 (L2) centric inter-cell mobility and inter-cell multi-TRP operation, a user equipment (UE) may need to measurement the downlink reference signals from neighbor cells. To obtain these measurements, a UE may perform layer 3 (L3) measurements for one or more neighboring cells, and provide an L3 measurement report to a network node. Candidate measurement neighboring cells for L1 measurements may be identified based on the L3 measurements.
