Abstract: The present disclosure provides signaling for multi-panel user equipment (MPUE) activation. The MPUE may have at least an active first panel and an inactive second panel. The MPUE may determine to activate the second panel. The MPUE may activate the second panel in response to the determination. The MPUE may transmit, from the active first panel to a base station, a status indicating that the second panel is active. The MPUE may transmit, after an activation time, an uplink transmission from the second panel to the base station.

Abstract: Aspects relate to mechanisms for wireless communication devices to signal for dynamically updating the configuration of a sound reference signal (SRS) resource set. A user equipment (UE) receives from a base station, via at least one of a downlink control information (DCI) or a medium access control (MAC) control element (MAC-CE), a configuration of one or more sounding reference signal (SRS) resource sets for SRS transmission. The UE also receives an indication of an update of one or more parameters, via at least one of the DCI or the MAC-CE, for at least one SRS resource set of the one or more SRS resource sets. The UE further applies the update to at least one SRS transmission.

Abstract: Aspects relate to a user equipment that transmits an uplink transmission on a first receive beam of a first beam pair link and on a second receive beam of a second beam pair link. A base station receives the uplink transmission on a first transmit beam of the first beam pair link and a second transmit beam of the second beam pair link via first and second transmission and reception points associated with the base station. The base station transmits a downlink transmission on the first transmit beam with a first beam-specific timing precompensation and on the second transmit beam with a second beam-specific timing precompensation. The first beam-specific timing precompensation and the second beam-specific timing precompensation are based on a timing difference between the reception of the uplink transmission via the first TRP and via the second TRP. The user equipment receives the beam-specific timing precompensations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a transmission configuration indicator (TCI) state that is associated with at least two signals or at least two communication channels. The UE may use the TCI state as the default beam to receive an aperiodic channel state information reference signal (CSI-RS) based at least in part on a scheduling offset between a scheduling downlink control information, which schedules the aperiodic CSI-RS, and a transmission time of the aperiodic CSI-RS being less than a beam switch latency threshold. Numerous other aspects are provided.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or base station. In one aspect, the apparatus may receive a channel state information (CSI) report configuration via radio resource control (RRC) signaling, the CSI report configuration including at least one of a channel measurement resource (CMR) resource setting, an interference measurement resource (IMR) resource setting, or a report quantity parameter. The apparatus may also determine a downlink receive beam of one or more downlink receive beams based on the CSI report configuration. The apparatus may also communicate with a base station via the downlink receive beam based on the determined downlink receive beam. Additionally, the apparatus may calculate a signal-to-interference-plus-noise ratio (SINR) quantity associated with a plurality of downlink transmit beams. The apparatus may also decode the CSI report configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information indicating whether a reference signal is associated with a full-duplex operation; receive the reference signal; and transmit feedback based at least in part on the reference signal and the information indicating whether the reference signal is associated with the full-duplex operation. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for configuration of resources to determine signal-to-interference-plus-noise ratio (SINR). A method that may be performed by a user equipment (UE) includes transmitting, to a base station (BS), an indication that the UE is configured with at least one capability to support a combination of a channel measurement resource (CMR) and at least one interference measurement resource (IMR), if group based beam reporting is configured, receiving a reference signal (RS) resource setting for the CMR to perform channel measurement based, at least in part, on the capability of the UE, receiving at least one RS resource setting for the at least one IMR to perform interference measurement based, at least in part, on the capability of the UE, determining at least one signal-to-interference-plus-noise ratio (SINR) parameter based on results of performing the channel measurement and the interference measurement, and transmitting the SINR parameter to the BS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, on a downlink control channel and a first beam, first downlink control information (DCI), wherein the first DCI identifies a second DCI that is carried on a downlink shared channel; and receive multiple repetitions of the second DCI on the downlink shared channel on a plurality of second beams.
