Abstract: Techniques for dynamic configuration of channel state information (CSI) processing units are disclosed. In an example, a user equipment (UE) may determine an operational state of the UE. The UE may also identify a number of channel state information (CSI) processing units that are supported by the UE for calculating and reporting one or more CSI reports based on the operational state of the UE. The UE may also transmit, to a base station, a notification indicating the number of CSI processing units.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a control resource set (CORESET) is not configured for an active downlink bandwidth part of a component carrier (CC) of the UE. The UE may determine that a transmission configuration indication (TCI) state is not activated for a physical downlink shared channel (PDSCH) of the active downlink bandwidth part of the CC. The UE may determine a default spatial relation for an uplink control channel or uplink signal for the CC based at least in part on determining that the CORESET is not configured for the active downlink bandwidth part of the CC and that the TCI state is not activated for the PDSCH of the active downlink bandwidth part of the CC. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes performing beam failure detection (BFD) of a beam pair link (BPL) associated with a secondary cell (Scell) of a base station (BS), sending a beam failure recovery request (BFRQ) message in another cell of the BS, the BFRQ message including an indication of a candidate recovery beam for the Scell, and starting a timer based on sending the BFRQ.

Abstract: Systems, apparatuses, and methods for switching between full duplex and half duplex in wireless nodes. A wireless node may measure self-interference for one or more transmitter-receiver beam pairs. Based on the self-interference measurements, the wireless node may communicate on a beam pair in full duplex or half duplex. A duplex mode may be determined based on self-interference, as well as, optionally with other metrics such as rate and latency. A wireless node may switch between full duplex and half duplex based on the duplex mode determination. In addition, suitable beam pairs may be selected, along with associated duplex modes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a set of beam failure detection reference signals to monitor for a set of secondary cells based at least in part on at least one of a cell configuration, a set of secondary cell reference signal selection rules, or a set of primary cell reference signal selection rules; monitor the set of beam failure detection reference signals based at least in part on determining the set of beam failure detection reference signals; and detect, based at least in part on monitoring the set of beam failure detection reference signals, a beam failure for a secondary cell of the set of secondary cells. Numerous other aspects are provided.

Abstract: An apparatus for wireless communication selects a recommendation for the need. The apparatus selects the resource to transmit a phase tracking reference signal based on a condition of a communication system. The apparatus performs at least one of transmitting an indication of the selected recommendation for the resource to a second wireless communication device or transmitting at least one of information or a reference signal to the second device to assist the second device in determining the resource. In an aspect, the selection may be made based on receiving a request for a recommendation from the second wireless communication device or the transmitting the at least one of the information or the reference signal are based on a request received.

Abstract: Apparatus, methods, and computer-readable media for facilitating spatial relation indication for uplink control channels and SRS are disclosed herein. An example method for wireless communication at a UE includes determining, based on a rule, a default uplink transmit beam for transmitting an uplink transmission when an uplink transmit beam is not configured by a base station for the uplink transmission. The example method also includes transmitting, to the base station, the uplink transmission on the default uplink transmit beam.
