Abstract: Methods, systems, and devices for wireless communications are described in which spatial relations for one or more uplink reference signal transmissions, such as sounding reference signal (SRS) transmissions, may be configured and a particular spatial relation indicated in a medium access control (MAC) control element (CE). A base station may configure a pool of available spatial relations for use in SRS transmissions, and the MAC-CE may indicate which spatial relation of the set of available spatial relations is to be used. In other cases, the MAC-CE may provide all of the spatial relation information for an associated SRS transmission. The UE, responsive to receiving the MAC-CE, may transmit a SRS to the base station using the indicated spatial relation.

Abstract: Methods, systems, and devices for wireless communications that support power control in full duplex communication are described. In some wireless communications systems, a user equipment (UE) may experience antenna isolation for communication of downlink and uplink data traffic. Based on the antenna isolation, the UE may realize an increased channel capacity for full-duplex communication. As part of the full-duplex communication, the UE may identify characteristics of a potential downlink signal on formatted slots of the channel. The UE may determine an uplink transmit power control configured to account for the characteristics. The determination may include a configured transmit power control for beamformed signaling at the UE, and may be based on signal reception quality for potential downlink transmissions. Based on the determination, the UE may either perform uplink transmission on a resource block allocation of the formatted slots or forgo uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described that provide for measurement and recovery of beamformed transmission beams in which an uplink beam and a downlink beam may be decoupled beams that use different beamforming parameters. In the event that a user equipment (UE) detects a failure of the downlink beam, an indication may be provided to a base station, and the downlink beam may be switched to correspond to the uplink beam. In the event that the UE detects a failure of the uplink beam the UE may identify a candidate beam and transmit a beam recovery message to the base station. The downlink beam may have an associated first set of reference signals, and the uplink beam may have an associated second set of reference signals, and beam failure may be determined based on the different sets of reference signals.

Abstract: Certain aspects of the present disclosure provide enhancements to enable per transmission reception point (per-TRP or per beam group)-based beam failure recovery, and more particularly, techniques for TRP-specific beam failure recovery request (BFRQ). A method that may be performed by a user equipment (UE) includes communicating using beams associated with at least two beam groups, each associate with one of the TRPs, detecting a beam failure in a first one of the beam groups, and transmitting an indication of a BFRQ specific to a beam group in which the beam failure was detected.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate to a UE a first set of uplink power control parameters associated with half-duplex communications and a second set of uplink power control parameters associated with full-duplex communications. Alternatively, the base station may indicate the first set of uplink power control parameters and a set of power offsets associated with full-duplex communications. The base station may indicate a first set of resources associated with the first set of uplink power control parameters and a second set of resources associated with the second set of uplink power control parameters or the set of power offsets. In response, the UE may transmit one or more uplink messages over one or more resources of the second set of resources in accordance with the second set of uplink power control parameters or the set of power offsets.

Abstract: Techniques and devices for wireless communications are described. A user equipment (UE) may receive a first message from a network entity that indicates a configuration for reporting spatial domain basis function updates to the network entity. The UE may transmit a full channel state information (CSI) report and a partial CSI report to the network entity based on the indicated configuration. The full CSI report may indicate a set of spatial domain basis functions and the partial CSI report may indicate an update for the set of spatial domain basis functions. The update for the set of spatial domain basis functions may be relative to the full CSI report or a previously transmitted partial CSI report. In some examples, the UE may receive a second message from the network entity based on the partial CSI report.
