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: 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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform measurements on one or more synchronization signals using a low power wake-up radio (WUR) of the UE. For example, the UE may receive first control information associated with a low power synchronization signal. In some examples, the first control information may include a periodicity of the low power synchronization signal and an indication of which measurements to perform on the low power synchronization signals. Based on the first control information, the UE may monitor, using the low power WUR, a resource occasion for the low power synchronization signal. Based on monitoring and receiving the low power synchronization signals, the UE may perform, using the low power WUR, the measurements of the low power synchronization signal. The UE may transmit a report including the measurements of the low power synchronization signal based on performing the measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant—small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a class indication that indicates a wake up radio (WUR) class associated with the UE, the UE comprising a WUR and a main radio, and the WUR class may correspond to a configuration characteristic of the WUR. The UE may perform a wireless communication action based on the configuration characteristic of the WUR. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communication system, a user equipment (UE) may receive an indication of multiple search space set groups (SSSGs), where a respective SSSG may be associated with a respective parameter set. Parameters in a parameter set may be power-saving parameters, reliability parameters, or a combination thereof. The UE may receive control signaling indicating a switch from a first SSSG to a second SSSG. The UE may switch from the first SSSG to the second SSSG and apply a first parameter set to the second SSSG, where the second SSSG is associated with (e.g., mapped to) to the first parameter set. In some examples, the SSSGs may be associated with respective scheduling request configuration groups (SRCGs), which the UE may use to transmit SRs to the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a policy for ordering multiple uplink shared channel resources granted for transmission of multiple transport blocks (TBs). The UE may assign data from one or more logical channels to multiple uplink shared channel resources in an order specified by the configured policy. In some examples, the UE may assign data from logical channels to uplink shared channel resources in a chronological order in which the uplink shared channel resources are scheduled, in a transport block size order of transport blocks to be carried in the uplink shared channel resources, in a modulation size order of the modulation orders associated with the uplink shared channel resources, or based on which uplink shared channel resources include uplink control information.

Abstract: A UE receives a configuration indicating priority levels for each of multiple logical channels. The UE schedules one or more packets for uplink transmission according to a priority level of a logical channel associated with a respective packet of the one or more packets and adjusts scheduling in response to a residual delay budget of a packet exceeding a delay threshold. The UE transmits the uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications system, a base station may schedule multiple user equipment (UEs) for unicast transmissions using a single downlink control information (DCI) format. For example, a first UE may receive, from a base station, DCI that includes unicast scheduling information for multiple UEs including the first UE. The first UE may determine, from the unicast scheduling information, a set of resources on which to communicate data with the base station. In such cases, the UE may transmit or receive data transmissions using the determined set of resources. In some examples, each UE of the multiple UEs may determine respective sets of resources based on one or more UE-specific transformation rules applied to common scheduling parameters of the DCI.
