Abstract: A communication method and an apparatus. The method includes receiving a first message from a first relay device, where the first message includes an identifier of a first terminal device, and the identifier of the first terminal device is a layer 2 identifier of the first terminal device, an adaptation layer identifier of the first terminal device, or an identifier allocated by the first relay device to the first terminal device; communicating with the first terminal device based on the identifier of the first terminal device. Therefore, the second terminal device may identify, based on the identifier of the first terminal device, data sent to the relay device from a protocol layer below a radio link control (RLC) layer or receive data from the relay device, to determine that a source terminal device or a destination terminal device associated with the data is the first terminal device.

Abstract: A communication method and a related apparatus. The method is applied to a first terminal device, and the first terminal device is a terminal device that uses sidelink discontinuous reception (SL DRX). The method includes: sending a first message to a second terminal device, where the first message includes a first resource set, and the first resource set is used by the second terminal device for sidelink (SL) transmission; and using a resource corresponding to the first resource set as activation time of the SL DRX, or disabling the SL DRX on the resource corresponding to the first resource set; and monitoring sidelink control information (SCI) on the resource corresponding to the first resource set, where the SCI includes SCI from the second terminal device. Embodiments are implemented to avoid impact on quality of communication between terminal devices.

Abstract: Embodiments of this application provide a wireless communication method, an apparatus, and a system. The method includes: obtaining mode information of a second terminal device, where the mode information indicates a resource scheduling manner of the second terminal device; and sending assistance information to the second terminal device based on the mode information, where the assistance information indicates one or more sets of sidelink transmission resources. Based on this solution, it can reduce resource conflicts or resource wastes, and therefore can properly and effectively allocate the sidelink transmission resource. In this way, sidelink communication efficiency can be improved.

Abstract: A relay communication method includes receiving, by a first relay device, first indication information from first user equipment. The first indication information indicates the first relay device to receive, through a first unicast connection corresponding to first security, configuration information from the first user equipment. The configuration information is used for a second unicast connection for communication between the first user equipment and second user equipment through the first relay device. The relay communication method also includes receiving, by the first relay device, first configuration information from the first user equipment through the first unicast connection corresponding to the first security. The relay communication method further includes communicating, by the first relay device, with the first user equipment based on the first configuration information through the second unicast connection.

Abstract: Embodiments of this application provide a relay communication method, apparatus, and system. In the method, when a first terminal device communicates with a second terminal device through a relay device, the first terminal device sends an RB configuration to the second terminal device by using the relay device. The RB configuration includes the first identifier and a PDCP entity configuration; or the RB configuration includes the PDCP entity configuration, and the PDCP entity configuration includes the first identifier. According to the method in this application, the first terminal device and the second terminal device may perform data transmission by using the same security protection parameter, to ensure correctness and effectiveness of data security protection in a process in which the first terminal device communicates with the second terminal device through the relay device.

Abstract: Embodiments of this application provide a sidelink communication method and an apparatus. The method includes: When a first terminal device (a transmitting end) has to-be-sent first data or first signaling, the first terminal device first determines whether the first data or the first signaling supports multicast or broadcast SL DRX. When the first data or the first signaling supports multicast or broadcast SL DRX, the first terminal device obtains an SL resource corresponding to multicast or broadcast SL DRX, and sends the first data or the first signaling by using the SL resource corresponding to multicast or broadcast SL DRX. Therefore, it can be ensured that the receiving end terminal device can successfully receive the first data or the first signaling that supports multicast or broadcast SL DRX, thereby improving SL communication quality.
