Abstract: A communication method and apparatus are provided. The method includes: A terminal device obtains first information, where the first information is used for mobility management of ascending-orbit and descending-orbit cells, and the first information is related to a latitude location. The terminal device performs the mobility management based on the first information. According to the method, in a scenario of ascending-orbit and descending-orbit cells in a satellite network, mobility management does not need to be frequently performed with frequency switching of ascending and descending orbits. In this way, efficiency of the mobility management of the terminal device can be improved, and system signaling overheads can also be reduced.

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.
