Abstract: The present disclosure discloses example communication methods, apparatuses, and mediums. One example method includes selecting a target side identifier corresponding to a communication type by a media access control (MAC) entity of a first terminal device, where the communication type includes unicast communication, multicast communication, or broadcast communication, and the target side identifier includes a destination layer 2 identifier or a destination layer 1 identifier. A first sidelink logical channel (LCH) is obtained by the MAC entity of the first terminal device, where the first sidelink LCH is an LCH having a highest priority among LCHs that correspond to the target side identifier and the communication type and that have data. A transmission resource to data on the first sidelink LCH is allocated by the MAC entity of the first terminal 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.
