The present disclosure relates to methods and communication apparatus for providing a network slice. In one example method where an access network device accessed by a terminal device does not support a network slice requested by the terminal device, the terminal device sends a network slice identifier, corresponding to a protocol data unit (PDU) session, to the access network device by including the network slice identifier in an radio resource control (RRC) message. The access network device may learn of the network slice identifier, and when the access network device does not support the network slice, search, in an access network device corresponding to a neighboring cell, for a target second access network device that supports the network slice.

Embodiments of this disclosure provide a signal quality information obtaining method, a device, and a system. One example method includes: a source network device obtains configuration information of an SRS of a terminal device and sends the configuration information of the SRS to a target network device and the terminal device. A first cell of the target network device monitors the SRS based on the configuration information of the SRS, and then the target network device sends, to the source network device, signal quality information of the SRS detected by the first cell. Correspondingly, the source network device receives, from the target network device, the signal quality information of the SRS detected by the first cell, where the first cell is a cell controlled by the target network device, the first cell is an energy-saving cell, and the energy-saving cell is a cell that does not send an SSB.

This disclosure relates to techniques for a wireless device to autonomously perform certain cell measurements in a wireless communication system. A wireless device may establish a wireless link with a cellular base station. The wireless link may be established according to a first radio access technology. The wireless device may determine whether at least one cell that operates according to a second radio access technology is available at the current location of the wireless device based on information stored by the wireless device.
