Abstract: Methods, systems, and devices for wireless communications are described. For example, a source distributed unit (DU) may receive, from a user equipment (UE), a measurement report indicating at least one transmission configuration indicator state (TCI) state associated with a target DU. The source DU may transmit, to the target DU, an indication of a set of candidate TCI states from the at least one TCI state for a dynamic cell switch of the UE from a source cell of the source DU to a target cell of the target DU. As such, the UE may transmit, to the target DU, a random access message or an uplink message in accordance with a first TCI state from the set of candidate TCI states.

Abstract: In operation, the UE in the cell (SpCell/SCell) may be configured to operate with beam group specific BFRs, cell-level BFRs, or combinations of them under a beam failure configuration that is determined according to various rules. A method of wireless communication performed by a user equipment (UE) and a UE is disclosed. The method includes determining a beam failure configuration for a serving cell, the beam failure configuration including at least one of a beam failure parameter of a beam group or a beam failure parameter of a cell; and detecting, in the serving cell based at least in part on the beam failure configuration, a beam failure recovery (BFR) based at least in part on the beam failure configuration. The beam failure configuration is determined based on various rules that control the operation of the BFR.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, as a transmission configuration indicator (TCI) state for a channel or reference signal (RS) in a bandwidth part (BWP), a TCI state associated with: a TCI list received in a radio resource control (RRC) message for the BWP; a codepoint identifier (ID) activated by a medium access control control element (MAC CE) for the BWP; or a scheduling downlink control information (DCI) for the channel or RS, based at least in part on determining that the UE has not received an indication of the TCI state for the channel or RS, or quasi co-location (QCL) information that indicates the TCI state for the channel or RS. The UE may transmit or receive a communication using the selected TCI state. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling that includes an indication that the UE is configured to report multiple values associated with maximum permissible exposure. Each of the multiple values may be of a same type but associated with different transmission aspects of the UE, the different transmission aspects including at least different transmission beams or different antenna panels. The UE may transmit a first maximum permissible exposure value associated with a first transmission aspect of the UE. The UE may transmit a second maximum permissible exposure value associated with a second transmission aspect of the UE and transmitted as a differential value based at least in part on the first maximum permissible exposure value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate using a first subcarrier spacing (SCS). The UE may switch from the first SCS to a second SCS for reception, from a second UE associated with the second SCS, of a reference signal for inter-UE cross-link interference (CLI) measurement. The UE may switch back to the first SCS after receiving the reference signal. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a network node, an indication that a bidirectional full duplex sidelink transmission between the first UE and a second UE is feasible. The first UE may transmit, to the network node, sidelink scheduling information that is recommended for the bidirectional full duplex sidelink transmission. The first UE may receive, from the network node, downlink control information (DCI) that schedules the bidirectional full duplex sidelink transmission, the DCI being based at least in part on the sidelink scheduling information and the indication that the bidirectional full duplex sidelink transmission between the first UE and the second UE is feasible. The first UE may transmit, to the second UE, the bidirectional full duplex sidelink transmission. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is to monitor physical downlink control channel (PDCCH) candidates in overlapping PDCCH monitoring occasions in multiple control resource sets (CORESETs) having different quasi co-location type properties on active downlink bandwidth parts of one or more cells, where the UE is configured with multiple downlink control information based multiple transmission/reception point operation. The UE may determine a set of prioritized CORESETs, each of the set of prioritized CORESETs being included in a respective CORESET group of a set of CORESET groups, and monitor one or more PDCCH candidates in the determined set of prioritized CORESETs. Numerous other aspects are provided.
