Abstract: Aspects of the disclosure are directed to generation of N-port dynamic beams. For example, a user equipment (UE) may be using a 2-port predefined receive beam for communication with a wireless node. The UE may estimate a channel using the predefined receive beam to measure a rank2 reference signal received from the wireless node. The UE may generate a dynamic beam weight to maximize a communication parameter based on the estimated channel. The UE may then apply the dynamic beam weight to an antenna array.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, for each of one or more candidate beams in a set of candidate beams, a downlink throughput, an uplink throughput, a downlink power consumption, and an uplink power consumption. The UE may select a beam based at least in part on: at least one of the downlink throughput or the uplink throughput, at least one of the downlink power consumption or the uplink power consumption, and one or more throughput thresholds. The UE may communicate using the selected beam. Numerous other aspects are described.

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.

Abstract: A base station may configure a user equipment (UE) with a discontinuous reception (DRX), e.g., connected mode DRX (CDRX), and the UE may select a synchronization signal block (SSB) set to perform an SSB warm-up to wake up, search, and measure the SSB set to improve the performance of the UE during a DRX ON duration. The UE may select the SSB set based on a time difference of the SSB set relative to the DRX ON duration. The UE may be configured to wake up to measure one of a first SSB set or a second SSB set having a smaller time difference relative to the DRX ON duration.
