Abstract: Some techniques and apparatuses described herein provide sub-grouping of paging groups of user equipment (UEs) based at least in part on one or more parameters associated with a UE, such as a UE type of the UE or a measured channel condition at the UE. A base station may assign the UE to a paging sub-group based at least in part on the information associated with the one or more parameters. In some aspects, the base station may determine paging transmission parameters for the UE based at least in part on the information associated with the one or more parameters, such as a paging early indication (PEI) location, a beam where a PEI and/or a paging message is to be transmitted, a number of repetitions for a paging occasion, or the like.

Abstract: In a wireless communication system, a user equipment (UE) may measure synchronization signal blocks (SSBs) to evaluate neighbor cells. A UE configured with multiple potential receive beams may conventionally measure one receive beam per SSB. A UE may improve the speed of receive beam measurements by performing measurements using demodulation reference signals (DMRS) of physical broadcast channel (PBCH) symbols, which occur twice per SSB. The UE may perform a cell search for neighbor cells available to the UE in a synchronized network to determine a number of the neighbor cells and timing information for each of the neighbor cells. The UE may measure one or more receive beams using the DMRs of the PBCHs of SSBs received from the neighbor cells. Each receive beam may be measured during a beam switch time unit including a PBCH symbol from each of the neighbor cells according to the timing information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a beam management window based at least in part on one or more downlink traffic parameters satisfying a window opening condition. The UE may perform a beam sweep on a set of beams associated with one or more physical downlink shared channel (PDSCH) demodulation reference signal (DMRS) transmissions that are received during the beam management window. The UE may select, among the set of beams associated with the one or more PDSCH DMRS transmissions received during the beam management window, a beam to use to communicate with a network node based at least in part on one or more metrics associated with each respective beam included in the set of beams. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for filtering measurement results at a user equipment (UE). According to certain aspects, a UE may receive reference signals transmitted from a network entity, apply a non-linear filter to measurement results, obtained based on the received reference signals, to obtain filtered measurement results, and transmit, to the network entity, a measurement report based on the filtered.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that one or more thresholds are satisfied. The UE may estimate, based at least in part on the one or more thresholds being satisfied, for each beam at one or more beam levels on one or more antenna panels, an application layer throughput, wherein the one or more beam levels are each associated with a number of antenna elements. The UE may generate a set of candidate beams that includes one or more beams for which the respective estimated application layer throughput satisfies an application layer throughput requirement. The UE may select a serving beam for which the estimated application layer throughput satisfies the application layer throughput requirement with a fewest number of antenna elements. Numerous other aspects are described.
