Abstract: A carrier selection method and a base station are provided and are applied to the field of communications technologies. The carrier selection method includes: obtaining load status information corresponding to a control channel of a first base station on each carrier, where the load status information is used for indicating a load amount of the control channel; selecting, according to the load status information, from multiple carriers corresponding to the first base station, a carrier corresponding to a control channel with a relatively small load amount as an operational carrier for a second base station or a primary cell carrier for a user equipment served by the second base station. Carrier selection is implemented.

Abstract: A method includes: a first IAB node sets up a first RRC connection to a target IAB donor by performing RLF recovery. The first IAB node sends a first message to a second node by using an SRB 1 or an SRB 2 or the first IAB node sends a BH RLF indication to the second node. t The first IAB node sets up an RRC connection to a target IAB donor by performing RLF recovery and the second node is connected to a source IAB donor through the first IAB node. The second node may be triggered to set up an second RRC connection to the target IAB donor based on the first message or the BH RLF indication.

Abstract: Embodiments of this disclosure provide a communication method, and an associated communication apparatus, medium, and chip. In a communication method, a target access network device receives first information, where the first information indicates a relationship between a first network slice in a first network and a second network slice in a second network, and the first network is different from the second network. The target access network device performs access control from a terminal device to the target access network device based on at least the first information. In this manner, in embodiments of this disclosure, the target access network device can perform access control on the terminal device during cross-network access, to reduce an access latency, reduce a service interruption problem caused by session rejection of the terminal device, and ensure service continuity of the terminal device.

Abstract: This application provides a relay communications method and apparatus. A first terminal device receives, from a second terminal device, indication information used to indicate the second terminal device to stop providing a relay service between the first terminal device and a radio access network device. The first terminal device sends notification information to the radio access network device through a third terminal device, to notify the radio access network device that the first terminal device accesses the radio access network device by using a relay service of the third terminal device. In this way, the radio access network device may communicate with the first terminal device through the third terminal device.
