[0111] The configuration information can be a handover indication, used to indicate that the configuration parameters of power control, power margin report, and spatial relationship can be switched based on the first operating state of the secondary cell. The configuration information can include a handover indication (PowerControlSwitch) corresponding to the power control configuration parameters, a handover indication corresponding to the power margin report configuration parameters, and a handover indication corresponding to the spatial relationship configuration parameters, respectively.

[0112] The power control configuration parameters are related to the first operating state of the secondary cell, and are divided into power control configuration parameters corresponding to the active state and power control configuration parameters corresponding to the inactive state. In one embodiment, the power control configuration parameters corresponding to the first operating state include:

[0113] When the first operating state is inactive, the type of the reference link cell is a secondary cell, that is, the reference signal of the reference link is the reference signal of the reference link of the secondary cell.

[0142] The terminal was configured or reconfigured with an inactive secondary cell for transmitting the probe reference signal.

[0143] In one implementation, when the first operating state is inactive, the power margin report is sent through the Media Access Control Element (MAC CE) of the primary cell or the primary / secondary cell.

[0144] In one implementation, when the first operating state is an inactive state, the method further includes:

[0151] A4. The serving cell base station determines the configuration information corresponding to the first operating state. Taking the first operating state as an inactive state as an example, the configuration information for the inactive state is determined. This step can be represented as the base station determining UL SRS Resources (gNB determines UL SRS Resources).
