Example Embodiment
[0368] Embodiment 1: The network device explicitly configures the BFR process and the BFD RS set included in each BFR.
[0369] The network device explicitly configures K BFR processes (or K BFR processes of all bandwidth parts) for each bandwidth part of each serving cell of the terminal, and each BFR process includes a BFD RS set. Wherein, each BFR process may correspond to the transmission of one TRP or multiple TRPs, or the transmission of the entire cell; K is a positive integer.
[0370] For example, all BFR procedures on a serving cell are configured by parameters related to a BFR procedure list, such as a beam failure recovery procedure list (BeamFailureRecoveryProcedureList), which contains multiple BFR procedures, and each BFR procedure is configured by a high-level parameter. For example, the beam failure recovery process (BeamFailureRecoveryProcedure) parameter, each BFR process also includes a BFD RS set, such as q0, and the corresponding high-level parameter is f...
Example Embodiment
[0387] Embodiment 2: The network device explicitly configures the BFR process and the CORESET group corresponding to each BFR process. Among them, a CORESET group contains at least one CORESET.
[0388] The network device explicitly configures K BFR processes (or K BFR processes for all bandwidth parts) for each bandwidth part of each serving cell of the terminal, and each BFR process configures a CORESET group, which can be determined by high-level parameters. It is represented by a control resource set list (controlResourceSetList); wherein, K is a positive integer.
[0389] The CORESET group includes: CORESETs corresponding to one or more CORESET indexes configured by the network device, or CORESETs with high-level parameters configured as specific values, for example, the high-level parameter may be a control resource collection pool index (CORESETpoolIndex).
[0390] The specific signaling can be:
[0391] BeamFailureRecoveryProcedure::=SEQUENCE{
[0392] …
[0393] c...
Example Embodiment
[0414] Embodiment 3: The network device explicitly configures the number of BFR processes, and the terminal determines the corresponding CORESET group for the BFR process in a predefined manner.
[0415] The network device explicitly configures K BFR processes (or K BFR processes for all bandwidth parts) for each bandwidth part of each serving cell of the terminal, that is, only the number of BFR processes is configured, and K is a positive integer; the terminal A CORESET group is determined for each BFR process by predefined rules.
[0416] When the terminal detects that the RS associated with the CORESET group corresponding to any BFR process is lower than a certain threshold, it reports the BFR process index, or the CORESET group index or the BFD RS set index to the network device.
[0417] Optionally, the predefined rules include but are not limited to the following ways:
[0418] When one BFR process is explicitly configured for each bandwidth part, it can be pre-defined...
