Patent ID: 8879414

Claim:
A method for transmitting data in a wireless communication system, the method comprising: transmitting a first reference signal set and a second reference signal set that contain a plurality of reference signals for a plurality of nodes for determining a first node set and a second node set, wherein the first node set comprises a plurality of nodes for a transmission of downlink signals and the second node set comprises a plurality of nodes for a reception of uplink signals; allocating the first node set and the second node set respectively, wherein the first node set and the second node set are separately allocated for the transmission of downlink signals and the reception of uplink signals, wherein the plurality of reference signals included in the first reference signal set are for a plurality of nodes for measuring downlink path-loss, and the plurality of reference signals included in the second reference signal set are for a plurality of nodes for measuring uplink path-loss; communicating with a terminal through the first node set or the second node set; and receiving a feedback of a part or all of path-loss values for the plurality of nodes measured based on at least one of the first reference signal set and the second reference signal set from the terminal, wherein, when the feedback of a part of path-loss values for the plurality of nodes is received, a feedback of N smallest path-loss values of the path-loss values is received, and wherein a receiving order of the feedback for the plurality of nodes is determined according to a size of path-loss values for the plurality of nodes measured based on at least one of the first reference signal set and the second reference signal set from the terminal.
