Abstract: A method for transmitting a control signal to a relay node at a base station in a multi-input multi-output (MIMO) wireless communication system is disclosed. The method comprises configuring relay-resource element groups (R-REGs) in a unit of four resource elements (REs) contiguous in the ascending order of subcarrier indexes, except for resource elements for a reference signal (RS); allocating transmission resources to the control signal in a unit of the relay-resource element group; and transmitting the control signal to the relay node by using the allocated transmission resources, wherein the resource elements for the reference signal include resource elements for channel state information-RS (CSI-RS), which include resource elements for a channel state information RS to which a transmission power of 0 is allocated.

Abstract: A method is provided for performing power control by a first base station in a wireless communication system. The first base station acquires a parameter value related with signal strength of a second base station, determines an upper power limit of the first base station in consideration of the signal strength of the second base station and performs signal transmission in consideration of the upper power limit of the first base station. If a first condition including that the parameter value is equal to or more than a first threshold value is satisfied, the upper power limit of the first base station is an intermediate value. If a second condition including that the parameter value is less than the first threshold value is satisfied, the upper power limit of the first base station is a pre-determined value related with the transmit power of the first base station.
