Optionally, the at least two cells include at least one primary cell and/or at least one secondary cell.

Optionally, the measurement module 302 further includes:

a setting unit, configured to: when at least one reference state process is running and when a reference state reset condition exists, reset a target reference state.

The reference state reset condition includes one of the following cases:

at least one target resource is reset, reconfigured, activated, deactivated, or switched; and

configuration information corresponding to the reference state is reset or reconfigured.

The target resource includes at least one of the RS, the RS set, the BWP, the cell, the carrier, the bandwidth, or the bandwidth combination.

Specifically, the configuration information includes at least one of the following information:

a reference state configuration parameter; or

a target resource corresponding to the reference state.

Specifically, the target reference state includes one of the following information:

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

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.

Further, the setting unit is configured to:

reset at least some parameters of reference state configuration parameters corresponding to the target reference state.
