Abstract: This application relates to a communication method and device. A remote terminal device receives a first data packet from a relay terminal device by using an SRB1. The first data packet includes a first message and an SRAP header. The remote terminal device removes the SRAP header via an SRAP entity to obtain configuration information. The SRAP entity is determined before the SRAP header is removed. The remote terminal device configures the SRAP entity based on the configuration information. The remote terminal device may predetermine the SRAP entity.

Abstract: This application provides example communication methods, apparatuses, and non-transitory memory storage mediums. An example method includes receiving a first broadcast message sent by a second terminal device. The first broadcast message includes first cell information of the second terminal device. The example method further includes receiving a third message from a first network device. The third message comprises second cell information of the second terminal device, and the third message indicates a first terminal device to switch from a relay device of the first terminal device to the second terminal device. The example method further includes, when the first cell information is inconsistent with the second cell information, determining that the switch fails.

Abstract: This application provides a communication method and apparatus. Before a source terminal establishes a unicast connection to a first target terminal, the source terminal allocates a first identifier to the first target terminal based on a request of a relay terminal, where a bit length of the first identifier is less than or equal to 8 bits. The source terminal sends first data to the first target terminal, where the first identifier is configured in the first data. The relay terminal forwards the first data to the first target terminal for the source terminal based on the first identifier. In the foregoing solutions, the source terminal may send a message to a specific target terminal based on the first identifier and the bit length of the first identifier is less than or equal to 8 bits.

Abstract: This application provides a system information SI transmission method and apparatus. The method includes: The first terminal device receives a first request message sent by the one or more second terminal devices. The first request message is used to request to obtain M system information blocks SIBs or system information SI messages of a serving cell. The first terminal device determines N destination identifiers corresponding to the M SIBs or SI messages, where N is an integer greater than or equal to 1, and N≤M. The first terminal device sends, based on the N destination identifiers, the M SIBs or SI messages to the one or more second terminal devices in a broadcast or multicast manner. According to the method, the SI may be transmitted on an SL in the multicast or broadcast manner. This improves SI transmission efficiency and SI update efficiency.

Abstract: This disclosure provides a data transmission method and a communication apparatus. The method includes: A first device receives first scheduling indication information and second scheduling indication information from a second device, where the first scheduling indication information indicates a first transmission resource from the second device to the first device, and the second scheduling indication information indicates a second transmission resource from the first device to a third device. The first device receives transmission data from the second device on the first transmission resource. When the transmission data is successfully received by the first device, the first device sends the transmission data to the third device on the second transmission resource.

Abstract: Embodiments of this application provide a communication method and a network node thereof. The communication method may be applied to UE-to-network U2N relay communication. In the communication method, a first network node gNB-CU sends first information to a second network node gNB-DU, to trigger the second network node to allocate a local identity to a remote UE; and the first network node receives second information from the second network node, where the second information includes the local identity allocated by the second network node to the remote UE. Alternatively, a first network node sends first information to a second network node, where the first information includes a local identity allocated by the first network node to a remote UE. The first network node or the second network node communicates with the remote UE via a relay UE.

Abstract: A communication method, apparatus and storage medium are provided to resolve conflicts between different configurations of a terminal device. A first communication apparatus receives a first message from a network device. The first message includes first configuration information. The first communication apparatus receives or sends a discovery message and performs measurement based on the first configuration information by receiving or sending the discovery message. The measurement is measurement on signal quality of a sidelink between the first communication apparatus and a second communication apparatus. The first communication apparatus sends measurement information of the measurement to the network device.

Abstract: This specification discloses a relay communication method and an apparatus, and relates to the field of communication technologies, to ensure security in a relay user equipment (relay UE) discovery process. The method includes: Second user equipment broadcasts a layer 2 (L2) identifier, and first user equipment receives the L2 identifier of the second user equipment, and reports the L2 identifier of the second user equipment and signal quality of the second user equipment to a first access network device. Alternatively, a radio network temporary identifier (RNTI) of second user equipment is sent to first user equipment through a unicast connection. In a relay UE discovery process, leakage of a UE RNTI is avoided, and security of relay UE is ensured.
