Abstract: Certain aspects of the present disclosure provide techniques for per-rank uplink and downlink beam selection. An example method, performed at a user equipment (UE), generally includes measuring channel state information (CSI) reference signals (CSI-RS) associated with a plurality of beams, determining an uplink rank and a downlink rank, selecting, from the plurality of beams, a downlink beam for processing downlink transmissions, based on the CSI RS measurements and the downlink rank, and selecting, from the plurality of beams, an uplink beam for processing uplink transmissions, based on the CSI RS measurements, the uplink rank, and the downlink rank.

Abstract: Aspects described herein relate to receiving, from a base station, a transmit beam including a synchronization signal block (SSB) of multiple broadcast signals transmitted over multiple symbols, wherein receiving the transmit beam includes switching among multiple receive beams for each of the multiple symbols to receive a corresponding broadcast signal of the multiple broadcast signals, measuring a signal metric of each of the multiple broadcast signals as received via a corresponding receive beam of the multiple receive beams in a corresponding symbol of the multiple symbols, and selecting, based on the signal metric measured for each of the multiple broadcast signals, a receive beam of the multiple receive beams for communicating with the base station.

Abstract: Methods and apparatus for beam management where a beam is selected based on an estimated channel correlation matrix. The apparatus determines a channel correlation matrix based on downlink SSB reference signal received at the UE. The apparatus estimates a RSRP of a plurality of beams associated with an uplink channel based on the channel correlation matrix and associated beam weights. The apparatus selects a first beam from the plurality of beams having a highest estimated RSRP for communication with a base station. The apparatus communicates with the base station via the first beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a monitoring signal associated with one or more antennas. The UE may identify, based at least in part on the monitoring signal, a blockage associated with the one or more antennas. The UE may perform a beam search using a decreased frequency of occurrence of tracking occasions for the one or more antennas based at least in part on the identification of the blockage associated with the one or more antennas. Numerous other aspects are provided.

Abstract: A method of wireless communication by a user equipment (UE) includes determining a first synchronization signal block (SSB) to monitor beam management. The first SSB comprises a primary synchronization signal (PSS), multiple physical broadcast channels (PBCHs), and a secondary synchronization signal (SSS). The method also includes determining a list of receive beams for measuring the first SSB. The method further includes measuring the first SSB by measuring the PSS with a first beam from the list of receive beams, measuring, with a second beam from the list of receive beams, a first demodulation reference signal (DMRS) on a first PBCH symbol of a first of the PBCHs, measuring the SSS with a third beam from the list of receive beams; and measuring, with a fourth beam from the list of receive beams, a second DMRS on a second PBCH symbol of a second of the PBCHs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure one or more radio frequency (RF) chains of the UE to communicate using a second radio access technology (RAT) for a length of time. The UE may identify that the length of time satisfies a threshold. The UE may configure the one or more RF chains to the first RAT. The UE may initiate a beam measurement on the first RAT in a number of consecutive measurement occasions based at least in part on the length of time satisfying the threshold. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE implements the technique to select a number of component carriers (CCs) in both a first frequency range and a second frequency range. The UE determines a schedule for performing search and measurement in the selected number of CCs. The UE performs search and measurement in the selected CCs according to the determined schedule.

Abstract: Techniques for managing base station beam panic for new radio technologies may include a user equipment (UE) measuring a signal quality of a serving beam from a base station. The UE may determine the signal quality has decreased by at least a threshold amount, and enable a signal panic operation to search for a beam different from the serving beam, in response to the signal quality decreasing by at least the threshold amount.

Abstract: Scheduling with split symbols for beam management is described. An apparatus is configured to receive, from a network node, DL signaling including a symbol in a first slot, and to measure a first measurement of a first beam during a first time portion, and a second measurement of a second beam during a second different time portion, of the symbol. The apparatus is configured to communicate, with the network node, using the first or second beam based on at least one of the first measurement or the second measurement. Another apparatus is configured to provide, for a UE, DL signaling including a symbol in a first slot, and to communicate, with the UE, using the first or second beam based on a first and/or second measurement. The first and second measurements are of first and second beams during a first and second different time portions of the symbol, respectively.
