    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 for transmitting an uplink signal at a User Equipment (UE) in a wireless communication system includes receiving, from a Base Station (BS), an uplink scheduling grant for multi-antenna transmission; transmitting the uplink signal precoded using precoding information included in the received uplink scheduling grant to the BS; and retransmitting the uplink signal to the BS according to Acknowledgment/Negative Acknowledgment (ACK/NACK) corresponding to the transmitted uplink signal. The retransmitted uplink signal is precoded using precoding information included in a most recent uplink scheduling grant or a predetermined precoding matrix if an uplink scheduling grant for the retransmission is not received from the BS.

    Abstract: The present description discloses a method for transmitting an uplink signal through a non-licensed band from a terminal in a wireless communication system by applying carrier aggregation techniques. More specifically, the method is characterized by comprising the steps of: receiving an uplink scheduling grant from a base station; determining the availability of a non-licensed band; transmitting a signal for reserving resources if a non-licensed band is available; and transmitting an uplink signal to the base station via the non-licensed band on the basis of the uplink scheduling grant.
