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.

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: 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 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.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, relating to synchronization signal block (SSB) selection for paging occasions (POs). In an example, a UE may identifying a first SSB overlapping with or after a PO. The UE may further identify that a distance between the first SSB and the PO is less than a distance between a second SSB the PO, the second SSB located before the PO. The UE may further select the first SSB associated with loop operations based on identifying that the distance between the first SSB and the PO is less than a distance between the second SSB the PO.

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 solid-liquid contact electrification-based self-driving chemical sensor includes a container, a contact liquid, an electrode, a solid triboelectric layer, a rectifier, a load, and a displacement device. The contact liquid is placed in the container. The electrode may be actively or passively moved into the container to be immersed in or emerged from the contact liquid. The solid triboelectric layer surrounds and covers a surface of the electrode. The solid triboelectric layer includes a sensing layer which becomes a reacted sensing layer by reacting to a target analyte. The rectifier and the load are connected to the electrode. The displacement device is connected to the electrode or the container to perform a periodic reciprocating motion, so that the solid triboelectric layer is in contact with and separated from the contact liquid, thereby generating a surface charge transfer to generate an electrical output signal.

The UE may initiate a beam measurement on the first RAT in a number of consecutive measurement occasions based at least in part on the length of time satisfying the threshold. Numerous other aspects are described.

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.
