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.
