1. A method executed by a base station, comprising:
- transmitting a physical uplink control channel (PUCCH) reference cell information for a SCell in an RRC Connection Reconfiguration message; and
receiving uplink control information of the SCell on a PUCCH SCell if the PUCCH reference cell information is configured for the SCell;
receiving uplink control information of the SCell on the SCell if the SCell is the PUCCH SCell;
receiving uplink control information of the SCell on a PCell or a PSCell, if the PUCCH reference cell information is absent for the SCell and the SCell is not a PUCCH SCell;
wherein, the PUCCH SCell is a SCell configured with PUCCH.

Abstract
Provided in the present invention is a method, base station, and user equipment for configuring a serving cell group. The method includes: a base station transmitting 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.
