METHOD AND DEVICE FOR USE IN ENHANCING CARRIER AGGREGATION

摘要

Provided in the present invention are a method, base station, and user equipment for use in configuring a serving cell group. The method comprises: a base station transmits serving cell group configuration information to a user equipment having carrier aggregation capability, where the serving cell group configuration information indicates a reference cell used for transmitting uplink control information of a serving cell. The present invention allows the base station to flexibly configure multiple PUCCH reference cells and to configure different PUCCH reference cells on the basis of different cell loads.
