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.

Abstract: Various embodiments include methods for autonomous beam switching by a wireless device. A processor of the wireless device may measure signal parameters of signals received from a first synchronization signal block (SSB) beam of a base station monitored by the wireless device and other SSB beams of the base station, determine whether a difference in measured signal parameters of signals received from the first SSB beam and another SSB beam of the base station satisfies a signal quality difference threshold, and autonomously switching to the second SSB beam as the serving beam in response to determining that the difference in the measured signal parameters of signals received from the first SSB beam and a second SSB beam satisfies the signal quality difference threshold. The signal quality difference threshold may be listed in a table in memory or determined via machine learning.

Abstract: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may determine a plurality of antenna configurations for a plurality of channel frequencies. The UE may determine a set of signal strengths for at least one beam received at one or more antenna configurations of the plurality of antenna configurations for at least one of the channel frequencies. The UE may select, based on the set of signal strengths, a first antenna configuration of the plurality of antenna configurations. After selection of the first antenna configuration, the UE may communicate with a base station, in one or more channel frequencies based on the first antenna configuration.

Abstract: Various aspects of the disclosure relate to techniques for handling out-of-order grants. For example, upon detection of an out-of-order grant, the best scheduling policy for handing the out-of-order grants may be selected based on at least one traffic condition. In some aspects, a scheduling policy may involve canceling and regenerating out-of-order grants. In some aspects, a scheduling policy may involve reordering data units. In some aspects, a scheduling policy may involve designating a reorder time window.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may disconnect from a first radio access technology (RAT) service, independent of signaling from the first RAT service, after sensing that the UE has entered a coverage hole. The UE may use a connection to a second RAT service while in the coverage hole in association with disconnecting from the first RAT service. The UE may disconnect from the second RAT service, independent of signaling from the second RAT service, after sensing that the UE has exited the coverage hole and before expiration of a radio link failure (RLF) timer for the second RAT service. The UE may reconnect to the first RAT service before expiration of an RLF timer for the first RAT service. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, using a first subscription of the UE, a first communication connection associated with a first service. The UE may establish, using a second subscription of the UE, a second communication connection associated with a second service. The UE may operate in a dual subscriber identity module (SIM) dual active (DSDA) mode based at least in part on establishing the first communication connection and establishing the second communication connection. The UE may perform an action to maintain concurrent services, including the first service and the second service, while operating in the DSDA mode. Numerous other aspects are described.

Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to determine a schedule for transmissions on subchannels of multiple frequencies based on a set of UE-specific, dynamic, and performance related metrics or criteria. The metrics may include an estimated number of users on a subchannel, a best-bandwidth fit, channel loading conditions, transmission range, and quality requirements of an application, among others. Such a schedule for transmissions on subchannels of multiple frequencies may result in either an improved capacity utilization, an improved communication quality, or both.
