Abstract: A communication method includes a terminal device sending M compressed data packets. The M compressed data packets are obtained by compressing M data packets based on a first buffer. The terminal device reestablishes a PDCP layer without resetting the first buffer. The terminal device then sends N compressed data packets. The N compressed data packets are a part or all of the M compressed data packets. When reestablishing the PDCP layer, the terminal device does not reset the first buffer. In this case, if the terminal device needs to retransmit a data packet, the terminal device may retransmit a previously obtained compressed data packet, and does not need to compress the data packet again.

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.

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.
