    Abstract: The present disclosure provides signaling for multi-panel user equipment (MPUE) activation and deactivation status. The MPUE may include a plurality of panels. The MPUE may determine a nominal number of active panels. The MPUE may map a number of panel identifiers equal to the nominal number of active panels to an actual number of active panels of the plurality of panels. The MPUE may receive, from a base station, a downlink control information (DCI) scheduling a communication based on one of the panel identifiers. The MPUE may determine a panel for the communication based on the mapping. The MPUE may communicate according to the DCI using the determined panel.

    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify a resource for wireless communication, the resource being in a first state where the resource is active for wireless communication and is inactive for a communication failure recovery procedure. The wireless device may determine that a communication failure has occurred during a first communication period. In some cases, one or more techniques for confirming the communication failure may be used to verify the failure. The wireless device may transition during a second communication period and based at least in part on the communication failure, the resource to a second state where the resource is inactive for wireless communication and is active for the communication failure recovery procedure. The wireless device may perform the communication failure recovery procedure using the resource transitioned to the second state.

    Abstract: Wireless communication systems and methods related radio link failure monitoring and handling in full-duplex communications are provided. A user equipment communicates, with a base station, in a full-duplex mode using a first uplink beam and a first downlink beam. The user equipment detects a beam failure of at least one of the first uplink beam or the first downlink beam. The user equipment determines whether the beam failure is associated with self-interference in the full-duplex mode. The user equipment determines, based at least in part on the determination that the beam failure is associated with the self-interference in the full-duplex mode, to refrain from declaring a radio link failure.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) with the capability to support a single active TCI state may receive configuration signaling which configures the UE with an active transmission configuration indication (TCI) state corresponding to a first beam for a control resource set and a shared data channel. The UE may perform a random access channel procedure to select a second beam from a set of different beams. The UE may update a quasi co-location (QCL) assumption for the control resource set to correspond to the second beam and deactivate the active TCI state based on updating the QCL assumption. The UE may then monitor the control resource set, the shared data channel, or both, using the second beam. The UE may deactivate the TCI state and use the indicated downlink beam so that the UE does not exceed its capability.

    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for dynamic updates to beam failure detection (BFD) reference signals (RSs) and path loss RS using medium access control-control element (MAC-CE) or downlink control information (DCI). For example, the quasi co-location (QCL) of periodic CSI-RS may be dynamically updated by the MAC-CE or DCI when the periodic CSI-RS is for BFD RS. Also, a semi-persistent CSI-RS or aperiodic CSI-RS may act as a BFD RS. An enhanced update procedure may be used to update the path loss RS dynamically using MAC-CE or DCI. In some cases, the path loss RS parameters updated via MAC-CE or DCI may overwrite the previously RRC configured path loss RS parameters. In another example, if the path loss RS is not configured, then the path loss RS by default may be the spatial relation reference signal of the corresponding uplink beam.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station via an uplink control channel, a negative acknowledgement (NACK) when a downlink shared channel transmission is not successfully received at the UE. The UE may receive, from the base station and based at least in part on the NACK, one or more channel state information reference signals (CSI-RSs) at one or more semi-persistent CSI measurement occasions. The UE may transmit, to the base station, one or more CSI reports at one or more semi-persistent CSI reporting occasions corresponding to the one or more semi-persistent CSI measurement occasions, wherein the one or more CSI reports include one or more channel measurements based at least in part on the one or more CSI-RSs. Numerous other aspects are provided.

    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for wireless communications by a user equipment (UE). Embodiments include reporting, to a network entity, a capability of the UE to support beam failure recovery (BFR) on one or more secondary cells (SCells). Embodiments include detecting a beam failure of a beam pair link (BPL) associated with an Scell of the one or more SCells. Embodiments include performing a BFR in accordance with the reported capability, in response to the detection.

In some aspects, a user equipment (UE) may select, from a plurality of search space sets associated with a plurality of control resource sets, a subset of the plurality of search space sets to monitor. The UE may monitor the subset of the plurality of search space sets, to receive a downlink control information message, for a physical downlink control channel beam associated with the subset of the plurality of search space sets. Numerous other aspects are provided.

    Abstract: Certain aspects of the present disclosure provide techniques for control channel resource grouping and spatial relation configuration. Aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes receiving an indication of one or more groupings of one or more control channel resources within a configured bandwidth. Each grouping is associated with a spatial relation. The UE applies a spatial relation for a control channel transmission using one or more control channel resources in a grouping of the one or more groupings. The grouping is associated with the spatial relation.
