Background In a multiple transmission reception point (Multi Transmission Reception Point, M-TRP) scenario, MTRP of single-DCI and MTRP scenario of Multi-DCI are included. When Multi-DCI (also referred to as M-DCI), each transmission/reception point (Transmission Reception Point, TRP) transmits its own TRP-related transmission resource indicator and transmission configuration indicator (Transmission Configuration Indication, TCI) status via its own downlink control information (Downlink Control Information, DCI). Each CORESET of the plurality of control resource sets (Control Resource Set, CORESET) is configured with a control resource set pool index (CORESETPoolIndex), and different CORESETPoolIndex corresponds to different TRPs. The default failure detection resource set (Failure Detection resource set) may be determined from TCIstate of CORESET contained in CORESETPoolIndex. When Single-DCI (also referred to as S-DCI), one DCI may transmit transmission resources and transmission configuration indications of a plurality of TRPs. The failure detection resource set of different TRPs in the S-DCI can be the display configuration of the base station or the determination of the terminal according to the default rule. For each set of failure detection resources, a reference signal identity (qnew) for a target beam (a new beam) may be determined from a corresponding set of candidate beam reference signals to inform the base station that the new beam may be used for transmission.
