Abstract
The present invention provides a method for transmitting uplink control information in coordinated multi-point system. According to an embodiment of the present invention, a method for feeding back channel state information of multiple transmission points in a coordinated multi-point cooperating set is provided, and the method includes: receiving reference signals of the multiple transmission points; based on the reference signals of the multiple transmission points, evaluating channel state information of each of the multiple transmission points; multiplexing and transmitting the channel state information of the multiple transmission points on a physical uplink control channel (PUCCH) of one of the multiple transmission points in a predetermined mapping sequence. The present invention solves the problem caused by coordinated multi-point as to how a user equipment feeds back uplink control information of multiple transmission points on a physical uplink control channel, and is beneficial to further development and application of the coordinated multi-point technology.
