Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) of a group of UEs may receive, from a group member of the group of UEs, traffic information including a transmission schedule associated with traffic of the group member UE. The UE may determine a discontinuous reception configuration for the group of UEs based at least in part on the transmission schedule. The discontinuous reception configuration may include a discontinuous reception schedule for the group of UEs. The UE may transmit, to the group of UEs, the discontinuous reception configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit control signaling indicating a set of beamforming configurations associated with a set of antenna panels at the UE. The UE may select one or more antenna elements of at least one antenna panel of the set of antenna panels based on a beamforming configuration associated with the at least one antenna panel. The UE may generate a set of beam weights for a wireless communication based on the beamforming configuration and the one or more antenna elements, and may use the generated set of beam weights to transmit the wireless communication. In some examples, the UE may include, in the control signaling, indications of a set of beamforming properties, a number of beam weights, a resource differential, or a combination thereof, associated with each beamforming configuration.

Abstract: The described techniques provide for the identification and utilization of different power consumption categories by a user equipment (UE) in wireless communications system. A power consumption category may correspond to a power consumption level (e.g., a powered circuitry configuration) of the UE. For example, a power consumption category may configure an analog-to-digital conversion (ADC) resolution, a digital-to-analog conversion (DAC) resolution, a number of antennas, etc., that a UE may employ for communications. In some examples, a UE may report capability information to a base station, and the base station may use the information to explicitly or implicitly (e.g., via conveying thresholds or conditions to the UE for power consumption category switching or power consumption category selection) configure the UE with various power consumption categories. As such, the power consumption categories may be used by the base station and UE, in some scenarios, for reducing power consumption.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, for full-duplex mode communication on a first link and a second link, a timing adjustment to at least one of a first timing or a second timing, wherein the timing adjustment is to cause a delay between clutter reflection from a first signal and an occurrence of a second signal to occur during a cyclic prefix of the second signal; cause the timing adjustment to be applied to the at least one of the first timing or the second timing; and communicate in the full-duplex mode with a first node and a second node in accordance with the timing adjustment, wherein communicating includes transmitting the first signal to the first node and receiving the second signal from the second node. Numerous other aspects are provided.

Abstract: A wireless node in a wireless multi-hop network may transmit, based at least in part on a change in multiplexing capability relating to communications on one or more radio link control (RLC) channels, information to at least one of a parent node or a child node that enables the at least one of the parent node or the child node to prioritize communications with the wireless node. The wireless node may transmit or receive communications prioritized according to the information with the at least one of the parent node or the child node.

Abstract: Aspects of the present disclosure provide techniques for configuring device-to-device (D2D) communication in new radio (NR) for one or more user equipments (UEs). Specifically, features of the present disclosure provide techniques for initial beam-pairing for sidelink communication that optimize communication resources (e.g., resource pools) by indicating the direction of traffic (e.g., transmit or receive) during the initial beam-pairing procedure and to establish sidelink communication without the need for scheduling request transmissions between the UEs.

Abstract: A UE may receive, from a base station/TRP, a configuration for a beam pair including an UL beam and a DL beam and transmit a RACH message via the UL beam while receiving DL information via the DL beam. The UE and/or the base station/TRP may be configured to operate in a FD mode. In aspects, the UE may transmit a RACH preamble based on a first mode of transmission. After a threshold time delay measured from the transmission of the RACH preamble, the UE may retransmit the RACH preamble based on a second mode of transmission. The second mode of transmission may be a same mode of transmission or a different mode of transmission from the first mode of transmission. Each mode of transmission may be based on one or more of TDM, FDM, or SDM.

Abstract: Aspects described herein relate to managing coexistence of multiple radio access technology (RAT) components in a device. Information related to an upcoming time period can be sent to a first radio access technology (RAT) component from a second RAT component. The first RAT component can select a resource to transmit a first RAT packet to minimize collision with the upcoming time period of the second RAT.

Abstract: Certain aspects of the present disclosure provide techniques for applying uplink transmission configuration indicator (TCI) states with downlink reference signals to codebook based physical uplink shared channel (PUSCH) transmissions. An example method generally includes receiving, from a network entity, signaling of an uplink transmission configuration indicator (TCI) state with a target codebook based uplink transmission signal, determining if the TCI state has a source downlink reference signal (RS) and deciding how to process the codebook based uplink transmission based on the determination.
