Patent ID: 8879484

Claim:
A method for processing a reference signal, comprising: sending, by an evolved NodeB (eNB) of a cell belonging to a coordinated multipoint transmission/reception (CoMP) set in a specified pilot position, a reference signal to a target user equipment (UE), and performing data puncturing with respect to data symbols that are simultaneously sent by an eNB of another cell in the CoMP set in positions corresponding to the specified pilot position; and obtaining the reference signal pilot position of the another cell in the CoMP set; wherein, the specified pilot position is orthogonally separated from a reference signal pilot position of another cell in the CoMP set; wherein the another cell is a cell other than a cell corresponding to the specified pilot position; and wherein the step of obtaining the reference signal pilot position of the another cell in the CoMP set comprises: negotiating with the eNB of the another cell in the CoMP set about the reference signal pilot position of the another cell in the CoMP set, wherein reference signal pilot positions of cells of the CoMP set after the negotiation are orthogonally separated in a time-frequency domain multiplexing mode; and sending information comprising rising a reference signal pilot position of a particular cell to the eNB of the another cell in the CoMP set; and wherein, the specified pilot position is the reference signal pilot position of the particular cell after negotiation.
