Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) that indicates a transmission configuration indication (TCI) state associated with a common bema for joint downlink and uplink communication, downlink communication only, or uplink communication only. The UE and the base station may communicate on one or more of a downlink or an uplink using the common beam associated with the TCI state indicated in the DCI. Numerous other aspects are provided.

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: Certain aspects of the present disclosure provide techniques for sharing machine learning models and an indication of transmission and reception points (TRPs) for which the machine learning models are applicable between wireless nodes such as user equipments (UEs) and base stations (BSs). For example, a UE receives an indication of one or more machine learning models associated with at least one TRP of one or more TRPs from a BS. The UE then uses the at least one of the one or more machine learning models for applications related to the at least one TRP. The applications may include a channel state information (CSI) compression, a cross frequency channel prediction, and a beam selection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an aperiodic channel state information reference signal (CSI-RS) report. The UE may determine, based at least in part on the DCI, a time duration between an end of the DCI and a start of a communication on a physical uplink shared channel that includes the aperiodic CSI-RS report. The time duration may be based at least in part on an aperiodic CSI beam switch latency threshold. The UE may generate the aperiodic CSI-RS report based at least in part on a CSI-RS measurement. The UE may transmit the aperiodic CSI-RS report based at least in part on the DCI associated with the time duration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a channel state information (CSI) report configuration associated with multiple reference signal resource sets, all reference signal resources in each reference signal resource set associated with a different base station beam, for one or more of channel measurements or interference measurements. The base station may receive a report, based at least in part on the CSI report configuration, that indicates one or more base station beams recommended for subsequent communications with a user equipment (UE). Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of at least one first beam and at least one first antenna panel of the UE, to use for one or more first transmissions, and of at least one second beam and at least one second antenna panel of the UE, to use for one or more second transmissions. Accordingly, the UE may communicate the one or more first transmissions, with the base station, using the at least one first beam and the at least one first antenna panel. Additionally, the UE may communicate the one or more second transmissions, with the base station, using the at least one second beam and the at least one second antenna panel. Numerous other aspects are provided.

Abstract: Various aspects of the disclosure relate to use of a default communication configuration for cross carrier wireless communication. For example, a wireless communication device such as a user equipment (UE) may use a default communication configuration that includes quasi-colocation information (e.g., a default CORESET configuration) for communication on a secondary component carrier (SCC). The default communication configuration may be used, for example, in scenarios where a CORESET is not defined for the SCC and other configuration information is not available. For example, other configuration information might not be available due to a short time gap between a grant sent on a primary component carrier (PCC) and the communication on the SCC scheduled by the grant.

Abstract: Aspects described herein relate to communicating a beam report that includes beam measurements performed by one or more antenna panels and an identifier of the one or more antenna panels. The beam report may be used to determine a number of antenna panels supported by a user equipment (UE) transmitting the beam report, which may be used in configuring the UE for communicating with one or more other devices.

Abstract: When a beam failure is detected, appropriate actions may be taken to recover the connection. A beam failure recovery request may be sent by a user equipment (UE) apparatus to initiate the recovery of the connection. The UE detects a beam failure for at least one active downlink and uplink beam pair for full duplex communication with a secondary cell (SCell). The UE transmits a beam failure recovery request (BFRQ) for the SCell to a base station using an uplink resource of the SCell or a primary cell (PCell) based on a layer 1 signal to interference and noise ratio (L1-SINR) measurement for the at least one active downlink and uplink beam pair of the SCell.

Abstract: A User equipment (UE) receives a control resource set (CORESET) configuration for a full duplex CORESET. The UE performs a measurement for full duplex operation based on at least one of a downlink beam or an uplink beam for full duplex beam failure detection based on one or more quasi co-location (QCL) relationships to one or more transmission configuration indication (TCI) states of the CORESET based on an absence of a configuration of a reference signal for the full duplex beam failure detection.
