Whether the terminal device supports the reference signal in the unconnected state or not can indicate whether the terminal device has the capability of using the reference signal in the unconnected state or not.
Wherein, the offset between the transmission time and the paging time of the reference signal may be at least one of:
an offset between a transmission time and a paging time of a reference signal supported by a terminal device corresponding to a Discontinuous Reception (DRX) scenario;

an offset between a transmission time and a paging time corresponding to a reference signal supported by a Long discontinuous reception (Long DRX) type terminal device;
an offset between the transmission time and paging time corresponding to a reference signal supported by a terminal device of Short discontinuous reception (SHORT DRX) type.
The offset between the transmission Time and the Paging Time of the reference signal supported by the terminal device corresponding to the e-DRX scenario may be used to indicate gap of eDRX in the eDRX scenario, that is, the first Paging Time (PO) within a Paging Time Window (PTW). It may also be used to indicate gap of DRX in eDRX scenarios, i.e. other POs within the PTW.
The offset may be a minimum offset between the transmission time and the paging time of the reference signal supported by the terminal device corresponding to each DRX scenario, or may be an offset expected by the terminal device, and may be specifically determined based on an actual terminal device requirement, which is not limited herein.

For example, the information indicating whether the terminal device supports the use of the reference signal in the unconnected state for secondary synchronization may be identification information, such as a bit in the first information, for explicitly indicating whether the terminal device supports the use of the reference signal in the unconnected state for secondary synchronization. Alternatively, the information indicating whether the terminal device supports the use of the reference signal in the non-connected state for assisting synchronization may be related configuration information, device usage information, or the like, for implicitly indicating whether the terminal device supports the use of the reference signal in the non-connected state for assisting synchronization. The offset between the transmission time and the paging time of the reference signal as described above can also be used as information indicating whether the terminal device supports the use of the reference signal in the non-connected state for assisting synchronization, to implicitly indicate whether the terminal device supports the use of the reference signal in the non-connected state for assisting synchronization.

Before releasing the context information of the terminal device, the core network device may laterally reflect the signal quality of the terminal device based on the number of times of repetition of transmitting data based on the control channel and/or transmitting service data based on the service channel. The higher the number of repetitions, the worse the signal quality of the terminal device, and further indicates that the terminal device uses coverage enhancement techniques in the connected state.
