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: 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: 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: 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.
