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: Disclosed are techniques for wireless communication. In an aspect, during a first synchronization wakeup period while RF circuitry and the FW circuitry are set to an active state, one or more measurements of one or more SSBs of a first SSBS from a base station. The UE predicts, during the first synchronization wakeup period while the RF circuitry and the FW circuitry are in the active state, a second SSBS at which to wake up for a second synchronization wakeup period based on the one or more measurements. In response to completion of FW post-processing operations, the UE transitions the RF circuitry and the FW circuitry from the active state to a sleep state.

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.

Abstract: A UE is configured to determine a set of parameters associated with receiving the SSBs, the set of parameters including a first parameter bitmap associated with a serving cell, a second parameter bitmap associated with the neighbor cell, and the SMTC. The UE is configured to determine a search window for searching the received SSBs based on the SMTC and at least one of the first parameter bitmap or the second parameter bitmap. The UE may measure the SSBs searched during the determined search window and send measurement results associated with at least a subset of the measured SSBs to the base station. The UE may also prune measurements to generate the measurement results by removing measurements associated with SSBs received in slots that are not indicated to expect SSBs, based on the first parameter bitmap, the second first parameter bitmap, or the SMTC.

Abstract: A wireless communication device can adaptively perform tracking loop updates for rude wake-up events when operating in a discontinuous reception (DRX) mode. In an aspect, the wireless communication device can perform one or more tracking loop updates, such as time tracking loop (TTL) updates and frequency tracking loop (FTL) updates, based on a time difference between a last tracking loop update and a warm-up occasion associated with a rude wake-up event being greater than a threshold. In addition, in response to the time difference being less than or equal to the threshold, the wireless communication device can perform the rude wake-up event without performing the one or more tracking loop updates.

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: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.
