Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. The method may include: A network device performs integrity protection on system information by using a first private key, and sends the system information, where the system information includes a first public key corresponding to the first private key and/or an index of the first public key. Correspondingly, a terminal device receives the system information from the network device, and if determining that the first public key is valid, the terminal device verifies integrity of the system information by using the first public key. According to this method, on one hand, the terminal device can effectively identify validity of the system information. On the other hand, because the system information includes the first public key and/or the index of the first public key, flexible update of an asymmetric key can be implemented.

Abstract: This application provides a communication method, a communication apparatus, and a terminal device. The method includes a first node that receives a first message of a terminal device that requests to associate the terminal device with the first node. The first node obtains information about a second node, where the second node is a group header of an upper layer group in which the terminal device is located. The first node performs data transmission as a relay between the terminal device and the second node. According to a solution provided in this application, the terminal device can perform normal communication.

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 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.
