Patent ID: 8706152

Claim:
A method of controlling uplink transmit power, the method comprising: (a) calculating an estimated path-loss value for each of downlink signals from a control base station and one or more neighboring base stations; (b) obtaining a signal path-loss value by using the calculated plurality of estimated path-loss values; and (c) obtaining an open-loop power control parameter by using the signal path-loss value, wherein, in operation (b), the signal path-loss is obtained based on an inter-cell cooperative communication scheme between the control base station and the neighboring base stations, wherein the inter-cell cooperative communication scheme combines an uplink signal received by the control base station and uplink signals respectively received by the neighboring base stations, wherein the signal path-loss value of operation (b) can be expressed by a function of a plurality of estimated path-loss values obtained in operation (a), wherein the inter-cell cooperative communication scheme selects an uplink signal with best quality from uplink signals received by the control base station, and wherein the signal path-loss value of operation (b) is an estimated path-loss value for a downlink signal having a smallest magnitude among signals received from the control base station and the neighboring base stations.
