A wireless device, such as a user equipment (UE), may receive first scheduling information with first resources for periodic transmissions with a first beam based on a half-duplex mode. The wireless device may receive second scheduling information for second resources associated with a second beam that is incompatible with the first beam for full duplex communication including downlink reception and uplink transmission that overlaps in time. The wireless device may adjust communication in response to the first beam being incompatible with the second beam for the full duplex communication.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) and a base station (BS) to determine channel state information (CSI) processing unit (CPU) occupancy of the UE. The UE and the BS may determine that at least one CPU from a CPU pool is occupied by an uplink CSI request from a CSI reference signal (CSI-RS) to at least a CSI request occasion. The UE and the BS may determine a number of occupied CPUs, for example, based on an accumulated or aggregated number of occupied CPUs for multiple CSI operations. The UE may perform a number of CSI operations based on the determined number of occupied CPUs. The BS may configure the UE to perform the number of CSI operations, for example, by transmitting one or more of a configuration, activation, or scheduling message.

The UE may determine from the control message the set of transmission occasions to apply power boosting. The UE may determine the transmit power for each transmission occasion based at least in part on the power boost configuration. The UE may transmit one or more uplink messages via the set of transmission occasions with the determined transmit power.

The one or more MAC-CEs may include a configuration of a plurality of codepoints. Each codepoint in the plurality of codepoints may be associated with one or more TRPs in a plurality of TRPs of the network node. The plurality of codepoints may be associated with at least one first TCI state for an uplink communication and at least one second TCI state for a downlink communication. The network node may transmit a single DCI message to the UE. The single DCI message may be indicative of at least one codepoint in the plurality of codepoints. The network node may communicate with the UE based on the at least one codepoint.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration of one or more conditional handover conditions associated with a first candidate cell. The UE may receive an indication of an operating mode associated with the first candidate cell. The UE may perform a conditional handover procedure based at least in part on the configuration of the one or more conditional handover conditions and the indication of the operating mode associated with the first candidate cell. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may defer transmission of a first feedback message to a target transmission time interval (TTI). During a reception time interval, a base station may transmit, to the UE, downlink control information (DCI) that triggers the UE to schedule a second feedback message, where the first feedback message and the second feedback message are associated with different types of hybrid automatic repeat request (HARQ) codebooks. The UE may compare a minimum processing time of the UE with a time difference between the reception time interval and the target TTI and determine (e.g., evaluate) whether to cancel transmission of the first feedback message based on the comparison. In accordance with the determining, the UE may transmit at least one of the first feedback message or the second feedback message.

Techniques for communicating hybrid automatic repeat request feedback

Methods, systems, and devices for wireless communications are described for receiver-assisted channel access in shared radio frequency spectrum. A receiver, such as a user equipment (UE) may transmit a measurement report to a transmitter, such as an access network entity, that indicates channel occupancy as measured at the receiver. In some cases, the receiver may identify resources for signal measurement and reporting that are configured by the transmitter, and provide an interference measurement report based on the signal measurements. The interference measurement report may indicate whether a channel is occupied, or an occupancy level of the channel. Resources may be configured for multiple beams, with the interference measurement report including interference measurements for the multiple beams. Further, the signal resources may provide resources for a listen-before-talk (LBT) procedure, through signal resource sets that span multiple slots.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first set of reference signals via a primary sidelink carrier of a sidelink carrier aggregation configuration and a second set of reference signals via one or more secondary sidelink carriers of the sidelink carrier aggregation configuration. The UE may receive, based on the reference signals, a measurement message indicating measurements for a set of beams corresponding to a secondary sidelink carrier of the sidelink carrier aggregation configuration based on a beam failure instance for the primary sidelink carrier. The UE may transmit, via Layer 1 signaling or Layer 2 signaling, a control message indicating to switch the primary sidelink carrier to the set of beams based on the measurements for the set of beams and the beam failure instance for the primary sidelink carrier.
