Claim 20:
21. A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program for execution by a processor of a base station, wherein the base station provides a carrier aggregation service for a terminal by using at least two serving cells, wherein the at least two serving cells comprise a first serving cell and a second serving cell, the program including instructions for:
receiving a communication failure recovery request from the terminal on an uplink channel of the second serving cell, the communication failure recovery request indicating a request to recover from a downlink communication failure of the first serving cell, wherein the communication failure recovery request comprises an index of the first serving cell and a candidate reference signal resource indication of the first serving cell; and
generating a communication failure recovery response, the communication failure recovery response indicating a downlink communication resource of the first serving cell; and
sending the communication failure recovery response to the terminal on a downlink channel of the second serving cell;
selecting from the serving cells in normal communication, a serving cell having the best channel quality of a downlink channel as the second serving cell, if there are a plurality of serving cells in normal communication.
