Abstract: A communication method, a base station, a radio communication node, and a user equipment are provided. A base station determines first resource configuration information, where the first resource configuration information is used for indicating N radio resource sets that are used when N radio communication nodes separately perform communication with a user equipment UE, and the radio resource includes a time domain resource and/or a frequency domain resource. The base station sends the first resource configuration information to the UE, where the UE communicates with a corresponding transmission point by using respective radio resource sets of transmission points, and the respective radio resource sets of the transmission points do not intersect. Therefore, a base station does not need to schedule a radio resource, thereby lowering a delay requirement on a backhaul link and eliminating interference.

Abstract: A tunnel establishment method and apparatus is disclosed. Even if an entity for executing the solution is not changed, a type of a tunnel established for each service of a terminal may be the same or may be different. For example, a first tunnel and a second tunnel may be established for a current service of the terminal, and a third tunnel may be established for a next service of the terminal. This eases congestion in a backbone network between a secondary access network node and a primary access network node. Alternatively, this avoids using a directly connected tunnel as a tunnel established between the secondary access network node and a core network user plane node when a core network control plane node needs to receive and send too much path switching signaling.
