Abstract: One example method includes sending, by a first terminal device, a first request message to a network device, where the first request message is used to request to establish a sidelink radio bearer (SL RB) between the first terminal device and a second terminal device, where the first request message includes at least one of a parameter index or at least one parameter. The first terminal device can then receive a first response message from the network device, where the first response message includes one or more of admission control indication information, the at least one parameter, the parameter index, or first SL RB radio resource configuration information, where the admission control indication information indicates that the network device allows establishment of the SL RB, and where the first SL RB radio resource configuration information includes at least one of an SL RB identifier or protocol layer configuration information.

Abstract: This application relates to the field of wireless communication technologies, and provides an information transmission method, an apparatus, and a communication system, to improve communication quality. In the method, a first terminal device receives first indication information from a second terminal device. The first indication information indicates capability information of the second terminal device, and the capability information of the second terminal device. The first terminal device sends second indication information to a network device. The second indication information indicates the capability information of the second terminal device. Based on the foregoing solution, the first terminal device may report the capability information of the second terminal device to the network device by using the second indication information.

Abstract: A sidelink communication method, a communication apparatus, and a communication system are provided, to perform sidelink communication configuration in a relay scenario. The method includes: A remote device sends first information to a relay device; the relay device receives the first information from the remote device, where the first information includes a first paging parameter of the remote device; the relay device sends second information to a first network device, where the second information includes the first paging parameter; the first network device receives the second information from the relay device; and the first network device performs sidelink configuration based on the second information. In this way, the first network device performs sidelink communication configuration based on the first paging parameter, so that quality of sidelink communication between the relay device and the remote device is improved, and scheduling flexibility of the first network device is improved.

Abstract: A wireless communication method includes receiving, by a terminal device, first information sent by a network device. The first information includes a first offset. The first offset is a difference between a frame number of a first system frame and a frame number of a first direct frame. The first system frame and the first direct frame overlap in a time domain. The wireless communication method also includes determining, by the terminal device, the first direct frame based on at least one of the first offset or the frame number of the first system frame.

Abstract: The present disclosure relates to sidelink communication methods and apparatus. In one example method, a terminal device sends first information to a network device, where the first information includes a first destination address, a first carrier index, and a first quality of service (QoS) parameter, and there is a correspondence between the first destination address, the first carrier index, and the first QoS parameter. The network device receives the first information from the terminal device. The network device determines sidelink radio bearer (SLRB) configuration information based on the first information, and sends the SLRB configuration information to the terminal device. The terminal device receives the SLRB configuration information from the network device.

Abstract: Embodiments of this application relate to the field of communication technologies, and disclose a communication method and apparatus, so that corresponding PDCP entities of a first terminal and a second terminal use consistent input parameters when executing security algorithms, thereby ensuring normal communication on a sidelink SL and improving communication reliability. A specific solution is as follows: A first terminal determines a logical channel identifier LCID meeting a preset condition, where a first packet data convergence protocol PDCP entity of the first terminal is associated with two or more logical channels LCHs; the first terminal receives a first data packet from a second terminal; and the first PDCP entity of the first terminal parses the first data packet based on the LCID.
