Abstract: Methods and apparatuses for beam failure recovery with cross-carrier beam management. A method for operating a user equipment (UE) includes receiving a carrier indicator field in a configuration for a first control resource set (CORESET) in a serving carrier of the UE and receiving first information indicating beam failure detection (BFD) reference signals (RSs) for the serving carrier. The carrier indicator field indicates another carrier that is different from the serving carrier. The first CORESET is with a transmission configuration indication (TCI) state associated with both the serving carrier and the other carrier. The method further includes determining, based on the carrier indicator field and the first information, one or more BFD RSs from the BFD RSs for the serving carrier to monitor the other carrier and determining, based on monitoring the one or more BFD RSs for the other carrier, whether to declare a beam failure for the other carrier.

Abstract: A method of operating a user equipment (UE) includes receiving downlink control information (DCI) indicating a plurality of transmission configuration indication (TCI) states; receiving first information in a control resource set (CORESET) configuration; and receiving second information indicating an association between one or more of the plurality of TCI states and the one or more CORESET groups. The first information indicates a value of CORESET group index provided by CORESETGroupIndex. The method further includes identifying, based on the CORESETGroupIndex indicated by the first information, a CORESET group of a CORESET in which a physical downlink control channel (PDCCH) carrying the DCI was received; determining, based on the identified CORESET group and the second information, a TCI state in the plurality of TCI states to use for reception of a physical downlink shared channel (PDSCH); and receiving the PDSCH using the determined TCI state.
