Abstract: The technology of this application relates to a relay communication method. After receiving first information sent by a first terminal device, a first radio access network device may determine, based on the first information, a second terminal device that provides, in a target cell, a relay service for the first terminal device, where the first information is used to indicate that the first terminal device is a terminal device with limited uplink power. The first radio access network device sends second information to a second radio access network device, where the second information is used to indicate the second terminal device that provides, in the target cell, the relay service for the first terminal device.

Abstract: This application provides example communication methods and example communications apparatuses, to implement bearer mapping for user data transmission. One example method is applied to a wireless backhaul system having a first network and a second network of different RATs. The example method includes obtaining, by a first management network element in the wireless backhaul system, information about a first radio bearer of a terminal in the first network, where the information about the first radio bearer is used to indicate the first radio bearer. The first management network element can then determine a mapping relationship between the first radio bearer and a second radio bearer based on the information about the first radio bearer, where the second radio bearer is a radio bearer of the first device in the second network.

Abstract: This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
