Provided are a method, device and system for selecting an uplink coordinated multi-point transmission (CoMP) set, which relate to the field of communications, and can determine an uplink CoMP set of a cell or a user equipment (UE) of a cell through configuration information about a channel state information-reference signal (CSI-RS) of a sub-cell in at least an interaction region between base stations. The method includes: a first base station receiving a first message sent by a second base station, the first message carrying configuration information corresponding to a CSI-RS of each of at least one second cell (S10); and at least according to the first message, the first base station selecting a cell in the at least one second cell and adding same to an uplink CoMP set of a first UE of a first cell (S11); wherein the at least one second cell is a cell under the second base station, and the cell in the at least one second cell is determined by a physical cell identifier (PCI) and the CSI-RS; and the first cell is a cell under the first base station. The technical solution provided in the embodiments of the present invention can realize sharing of control information and data information among a plurality of cells in a wireless communication system. |
