In other words, in this case, a reference state process performs measurement only on one bandwidth combination, and enables, based on a reference state configuration parameter corresponding to the reference state process, timing by a timer and counting by a counter. For example, when the reference state includes the RLM, an RLM process performs measurement only on one bandwidth combination, enables timing by a timer, and enables counting by an out-of-sync counter and/or an in-sync counter; when the reference state includes the BFD, a BFD process performs measurement only on one bandwidth combination, enables timing by a timer, and enables counting by a beam failure instance counter.

Further, the performing, based on the monitoring configuration parameter, a detection process corresponding to the reference state further includes:

when at least one reference state process is running and when a reference state reset condition exists, resetting a target reference state.

It should be noted that the target reference state includes one of the following information:

D1. a reference state configured for at least one of the terminal, the RS, the RS set, the BWP, the cell, the carrier, the bandwidth, or the bandwidth combination; and

D2. a reference state configured for at least one of an RS, an RS set, a BWP, a cell, a carrier, a bandwidth, or a bandwidth combination that have been reset.

Specifically, the reference state reset condition includes one of the following cases.

D1. At least one target resource is reset, reconfigured, activated, deactivated, or switched.
