Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may measure a reference signal over a first subset of a set of measurement occasions using a serving UE receive beam according to a serving beam measurement periodicity. The UE may measure the reference signal over a second subset of the set of measurement occasions using a first subset of candidate UE receive beams of a set of candidate UE receive beams. The UE may measure the reference signal over a third subset of the set of measurement occasions using a second subset of candidate UE receive beams of the set of candidate UE receive beams. The UE may perform beam switching to a candidate UE receive beam of the set of candidate UE receive beams based at least in part on a result of measuring the reference signal.

Abstract: A UE may be configured to select narrower or wider beams that may be suitable for use with a current UE mobility, scattering environment, etc. The UE may track changes to an identified beam of a certain width, and so may recover from tracking or other radio link failures by switching to a beam that is spatially adjacent or to a beam of a different width. The UE may identify a first beam associated with a first beam width based on at least one reference signal received by the UE. The UE may further determine a set of beams based on the first beam width that is associated with the identified first beam, and the determined set of beams may include at least one beam corresponding to the first beam width. The UE may further measure respective channel qualities associated with each beam of the determined set of beams.

Abstract: Techniques and devices for wireless communication are described. A communication device may identify a set of beam level selection parameters. The set of beam level selection parameters may include traffic information, channel information, application information, or any combination thereof. The communication device may select, based on the identified set of beam level selection parameters, a beam level, from a set of beam levels, different from a baseline beam level associated with the wireless communication. The selected beam level may be associated with a number of antenna elements different from a number of antenna elements associated with the baseline beam level. The communication device may perform the wireless communication based on the selected beam level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a first throughput on a first beam of the UE, wherein the first beam is associated with a first number of antenna elements. The UE may identify an estimated maximum throughput of the UE. The UE may communicate, based at least in part on the first throughput being greater than the estimated maximum throughput, using a second beam, the second beam having a second throughput that is greater than the estimated maximum throughput, and the second beam being associated with a second number of antenna elements lesser than the first number of antenna elements. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving a first set of multiple sets of synchronization signal block (SSB) signals from a network entity. The first set of multiple sets of SSB signals may be associated with a first antenna port of the network entity corresponding to a first polarization. Additionally, the UE may receive a second set of multiple sets of SSB signals from the network entity. The second set of multiple sets of SSB signals may be associated with a second antenna port of the network entity corresponding to a second polarization. The UE may then transmit an indication of a beam pair for communication between the UE and the network entity based at least in part on receiving the first set of multiple sets of SSB signals and the second set of multiple sets of SSB signals.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.

Abstract: Certain aspects of the present disclosure provide techniques for adapting search, measurement, and loop tracking periodicities in new radio communications. A method that may be performed by a user equipment (UE) includes determining, based on one or more parameters, a first periodicity to perform a search to detect one or more component carriers (CCs), cells, beams, or a combination thereof; a second periodicity to perform measurement of one or more cells, beams, or both in one more detected CCs; and a third periodicity to perform loop tracking to monitor a downlink serving quality, an uplink serving beam quality, or both of a cell. The method may further includes performing the search at the determined first periodicity, measurement at the determined second periodicity, and loop tracking at the determined third periodicity.
