Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a first antenna array and a second antenna array are active for the UE operating in a full duplex operation mode, where uplink signaling at the UE corresponds to the first antenna array and downlink signaling at the UE corresponds to the second antenna array. The first antenna array and the second antenna array may be associated with one or more operating parameters of the UE. The UE may select one antenna array of the first antenna array or the second antenna array to use for both the uplink signaling and the downlink signaling based on a value of the one or more operating parameters of the UE satisfying a first threshold value. The UE may communicate, in the full duplex operation mode, the uplink signaling and the downlink signaling using the selected antenna array.

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: Methods, systems, and devices for wireless communications are described. Multiple reference signal occasions may occur during an inactive period of a discontinuous reception cycle configured for a wireless device. An amount of time the UE will be awake during the discontinuous reception cycle if the UE wakes up during a reference signal occasion of the multiple reference signal occasions may be determined for each of the reference signal occasions. The UE may wake up during the reference signal occasion associated with the shortest amount of awake time relative to the other reference signal occasions.

Abstract: In a particular implementation, a method of wireless communication includes searching, at a user equipment (UE) having a first subscriber identity module (SIM) and a second SIM, transmit beams from a base station and receive beams from the UE to determine a subset of transmit beams. The method also includes storing indicators of the subset of transmit beams in a database accessible to the UE in response to the second SIM performing a particular operation that causes the first SIM to perform a tune away operation. The method further includes, after completion of the particular operation, performing measurement operations on the subset of transmit beams to select a particular transmit beam of the subset of transmit beams and a corresponding particular receive beam for attachment to the base station.

Abstract: Aspects of the disclosure relate to minimizing the number of antenna array modules on a wireless communication device utilized in forming beam pair links (BPLs) based on beam measurements obtained on each of a plurality of receive beams for each of a plurality of transmit beams. For at least one BPL, the wireless communication device selects a different receive beam that results in at least one fewer active antenna array module. In some examples, the different receive beam selected for a BPL has a beam measurement value within a predefined variance from a beam measurement value of an original receive beam for the BPL. In addition, the wireless communication device can confirm that the beam measurement values of both the original and different receive beams satisfy a minimum beam measurement value before switching the BPL to the different receive beam. Other aspects, features, and embodiments are also claimed and described.
