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: The method may include: after receiving, through a first interface or a second interface, resource allocation information of a neighboring cell of a serving cell in which UE is located, a network device may allocate a resource to the UE based on the resource allocation information of the neighboring cell, so as to prevent the UE from using a same resource as UE located in the neighboring cell, and reduce interference to the neighboring cell; or allocate, to the UE, a resource with relatively small interference to the UE, so as to reduce interference of the neighboring cell to the UE. The first interface is an interface that performs communication by using a UE-to-UE communications technology. The second interface is an interface that performs communication by using a UE-to-network device communications technology.

Abstract: A communication method and apparatus are provided, so that an access network device can configure an initial hyper frame number (HFN) and a reference sequence number (SN) for a terminal device in time when no data packet is received from a core network device. The method includes: A first core network device obtains an initial multicast/broadcast service (MBS) quality of service flow identifier (QFI) SN corresponding to a first MBS session, and sends the initial MBS QFI SN in a first procedure. The first procedure is a procedure before a the 1st data packet of the first MBS session is sent to an access network device. After receiving the initial MBS QFI SN in the first procedure, the access network device may determine an initial HFN and a reference SN based on the initial MBS QFI SN, and send the initial HFN and the reference SN to a terminal device.

Abstract: A communication method and a communication apparatus. In the method, a terminal device can obtain first resource information according to a preset rule or from a network device, where the first resource information includes at least one of frequency domain position information, a cyclic prefix, or a subcarrier spacing; and receive a multicast broadcast service in a radio access control (RRC) idle state or an RRC inactive state based on the first resource information. According to the method, a resource used when the terminal device receives the multicast broadcast service in the RRC idle state or the RRC inactive state can be determined, so that the terminal device can receive the multicast broadcast service in the RRC idle state or the RRC inactive state.
