Abstract: Aspects of the disclosure relate to power reduction measures that can be employed by wireless user equipment (UE) participating in an extended reality (XR) application. A wireless UE, while operating in a first power state, may receive, from an XR service provider, a plurality of packets corresponding to a video frame. The UE may reassemble and decode the received packets to reproduce the video frame. Once the UE determines it has received information sufficient to reproduce the video frame, the UE may enter a second power state, different from the first power state, for a predetermined amount of time. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects described herein relate to cross-link interference (CLI) measurement based on enhanced sounding reference signal (SRS) in fifth generation new radio (5G NR). In an example, the aspects may include receiving, by a first user equipment (UE) from a network entity, a SRS configuration; measuring, by the first UE, CLI between the first UE and a second UE based on the SRS configuration; and transmitting, by the first UE to the network entity, a measurement report of the CLI measurement to trigger CLI management between the first UE and the second UE.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: In the examples described herein, a user equipment (UE) may identify multiple carriers configured for communications with a base station, and the UE may group the carriers into one or more preferred groups for synchronized scheduling at the base station. The preferred groups of carriers for synchronized scheduling may represent a recommendation that carriers within a preferred group are to be scheduled for communications with the base station on at least partially overlapping resources to maximize power savings at the UE. The UE may transmit an indication of the preferred groups of carriers to the base station, and the base station may identify an actual group of carriers for synchronized scheduling based on the indication received from the UE. The base station may then schedule communications with the UE based on the actual group of carriers.

Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may decode a downlink communication on a physical downlink shared channel (PDSCH). The downlink communication may have punctured resources. The UE may transmit, in association with the downlink communication, a first uplink communication on a physical uplink shared channel (PUSCH), and measure self-interference in the punctured resources of the downlink communication on the PDSCH that are within a threshold distance of resources of the first uplink communication on the PUSCH. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for rate matching of synchronization signal block (SSB) transmissions in non-terrestrial networks (NTNs). A method that may be performed by a user equipment (UE) includes receiving configuration information indicating a beam-specific rate matching pattern for at least one beam of a plurality of beams configured for the UE, wherein a SSB transmission corresponding to each of the plurality of beams is configured using the same set of frequencies, receiving a data channel using the at least one beam, and processing the data channel based on the rate matching pattern.
