Abstract: This application provides a relay communication method, a communication apparatus, and a communication system, to effectively improve efficiency of accessing a cell of a network device by a remote terminal. The method is applied to a communication system including a first terminal, a second terminal, and a third terminal, and the first terminal is a relay device used by the second terminal to access a network device. The method includes: The first terminal receives system information from the network device, and determines, based on the received system information, that the second terminal fails to camp on a first cell of the network device. The first terminal sends first indication information to the second terminal, where the first indication information indicates to break a sidelink between the first terminal and the second terminal, or the first indication information indicates that the second terminal fails to camp on the first cell.

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: A core network delivers two sets of quality of service (QoS) parameters to an access network device. The access network device selects one of the two sets of QoS parameters, and indicates the selected set of QoS parameters to the core network. An air interface rate required by the set of QoS parameters can be supported by a radio access network (RAN). In this way, a QoS parameter applied to a related user equipment (UE), a related bearer, a related packet data unit (PDU) session, or a related QoS flow can be effectively determined, and a hardware capability of an LTE base station does not need to be upgraded. In addition, the core network may set, based on a QoS parameter selected by a RAN side, a corresponding QoS management policy such as a rate adjustment policy, to facilitate data transmission between UE and the core network.

Abstract: Embodiments of this application provide a communication method and a related device. The method includes: a network device firstly sends the configuration information to the user equipment, and then the user equipment obtains a first condition based on the configuration information. Then, in a measurement process, the user equipment sends a measurement report to the network device when determining that the first condition is currently met. After obtaining the measurement report, the network device indicates at least one candidate relay device to the user equipment by using a path switch command. The user equipment determines one relay device in the at least one candidate relay device, and communicates with the network device or another network device through the determined relay device.
