Abstract: An example communication method includes that a first terminal device receives through a first path a first data packet from a second terminal device. The first terminal device receives through a second path a second data packet from a second terminal device, where the first path has a mapping relationship with the second path. The first terminal device transmits, based on the mapping relationship, the first data packet and the second data packet to a same aggregation protocol layer entity to perform data aggregation processing.

Abstract: Example communication methods and apparatus are described. One example communication method includes receiving broadcast information by a terminal device. The broadcast information includes a first parameter and a second parameter that are for a first cell. The first parameter is used for cell selection or cell reselection performed by a terminal device that supports supplementary uplink (SUL) carrier transmission, and the second parameter is used for cell selection or cell reselection performed by a terminal device that does not support SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the first parameter when the terminal device supports SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the second parameter when the terminal device does not support SUL carrier transmission.

Abstract: The present application provides an information transmission method. A first base station sends a context of a terminal to a second base station according to a request of the second base station. The request message of the second base station includes a first identifier, the first identifier is an identifier of the terminal in a non-connected mode in an area configured by the first base station, and the context of the terminal includes a core network-related context. The second base station may perform a corresponding RRC configuration based on the obtained context of the terminal. The first base station uses a RAT different from the second base station.

Abstract: This application discloses an information transmission method in a communication system. According to the method, a master base station sends a request message to a secondary base station for requesting to transfer one or more flows from the master base station to the secondary base station for transmission to a terminal device. The request message carries one or both of identification information of each flow, and information of a data radio bearer (DRB) associated with each flow. The master base station receives a response message from the secondary base station, indicating whether each of the one or more flows is admitted or rejected by the secondary base station. Based on the identification information of the flows, DRBs are mapped to the flows. QoS management of information transmission is more refined, and requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
