Abstract: A user equipment (UE) may receive a first indication of a configured communication for a first set of symbols. The UE may detect a second indication associated with a second set of symbols. The UE may determine that a direction of the configured communication is different from an indicated direction for the second set of symbols, the second set of symbols at least partially overlapping the first set of symbols. The UE may cancel the configured communication or may communicate the configured communication based at least in part on a physical layer priority of the configured communication and based at least in part on the determination that the direction of the configured communication is different from the indicated direction for the second set of symbols.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a user equipment (UE) utilizing beam sweeping during a random access procedure to determine an uplink beam for subsequent communication with a base station. The UE may transmit a first message indicating a random access preamble for a random access procedure and a plurality of reference signals using a set of directional beams. The base station may receive the reference signals or information related to the reference signals and transmit a second message indicating a directional beam of the set of directional beams and a set of resources. Upon receiving the second message, the UE may transmit the third message over the set of resources using the indicated directional beam.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured to monitor a set of beams, and may request an update to a monitoring configuration based on a position of the UE, an orientation of the UE, a rate of change of the position or orientation, or any combinations thereof. In some cases, the position or orientation information of the UE may include information for a current time period, predictive information for one or more future time periods, other information, or any combinations thereof. The UE may transmit a beam monitoring request to a base station for an updated monitoring configuration, such as a subset of a set of configured beams or an identified scan angle to be monitored by the UE.

Abstract: Certain aspects of the present disclosure provide techniques for quasi co-location (QCL) reference signals for uplink transmission configuration indicator (TCI) states. An example method generally includes receiving uplink transmission configuration indicator (TCI) indicating one or more quasi co-location (QCL) types, from a plurality of uplink QCL types, for one or more source reference signals (RSs); and sending an uplink transmission in accordance with the uplink TCI.

Abstract: A configuration to enable a UE to select a new CSS set to use for monitoring for PDCCH based on changing conditions at the UE. The apparatus may receive, from a base station, a first indication of a search space for monitoring for a channel for at least one of system information, paging, or user data. A first set of monitoring occasions based on the search space indicated by the base station. The apparatus may determine a second set of monitoring occasions different than the first set of monitoring occasions based on a condition experienced by the apparatus. The apparatus may monitor for the channel based on the second set of monitoring occasions determined by the apparatus.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) reporting configuration for a CSI report, wherein the CSI reporting configuration indicates that the CSI report is to include a layer 1 signal to interference plus noise ratio (L1-SINR). The UE may determine a number of CSI processing units (CPUs) occupied for processing of the CSI report that is to include the L1-SINR. Numerous other aspects are provided.

Abstract: A user equipment (UE) may be provisioned with multiple semi-persistent scheduling (SPS) configurations and/or semi-static configured grants (CGs). The UE may receive a first message indicating a first set of parameters for a first SPS configuration or for a first CG. The UE may receive a second message including at least one updated parameter for a SPS configuration or a CG. The UE may determine that the second message is applicable to one or more SPS configurations or CGs including the first SPS configuration or the first CG. The UE may overwrite a corresponding parameter of the first set of parameters with the at least one updated parameter. The UE may receive according to the first SPS configuration or transmit according to the first CG based on the at least one updated parameter.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may schedule uplink control channel repetitions for a user equipment (UE) on multiple component carriers (CCs). The UE may determine spatial relation information to apply to each uplink control channel repetition based on a rule, where the rule specifies for the UE to apply same spatial relation information to the repetitions or different spatial relation information to the repetitions. In some cases, the UE may use spatial relation information from a first uplink control channel repetition (e.g., per-frequency band, per-CC subgroup, or for each of the uplink control channel repetitions). In some other cases, the base station may indicate different spatial relation information for each uplink control channel repetition in control signaling. The UE may transmit the uplink control channel repetitions using the spatial relation information.

Abstract: Methods, systems, and devices for wireless communications are described for beam selection based on user pose information provided by an extended reality (XR) application. The pose information may be used to determine a position of the UE, and one or more beam parameters may be requested based on the position of the UE. The position information of the UE may include position information for a current time period, predictive position information for one or more future time periods, or any combinations thereof. The UE may transmit a beam request to a base station for one or more beams for the current time period, for one or more future time periods, or any combinations thereof. The UE may request a switch between beams of differing beamwidths or having the same beamwidth, or request a change of a beamwidth of an existing beam.

Abstract: Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule the wireless nodes (e.g., access points and/or stations) operating within the cluster. For example, stations may be scheduled across basis services sets of the access points for a downlink transmission and/or an uplink transmission.
