Claim:
1. A method for implementing a coordinated multiple point transmission (CoMP), comprising: configuring, by a network side, a range setting group to a user equipment (UE); acquiring original mapping patterns of a reference signal (RS) corresponding to a plurality of cells in the range setting group based on identification (ID) of the plurality of cells; receiving channel information of the plurality of cells in the range setting group transmitted by the UE; selecting, by the network side, cells for transmitting data to the UE currently; determining update mapping patterns for the selected cells based on the acquired original mapping patterns of the RS; and transmitting the data on a physical downlink shared channel (PDSCH) to the UE based on the determined update mapping patterns for the selected cells, wherein the update mapping patterns for the selected cells are identical to each other, wherein the update mapping patterns is determined to comprise at least one resource element (RE) corresponding to mapping locations of a cell-specific reference signal (CRS) and a channel state information reference signal (CSI-RS) in the original mapping patterns, and the at least one RE is not used for transmitting data, and wherein after the selecting of the cells for transmitting the data to the UE and before the determination of the update mapping patterns, the method further comprises:
