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: A method for receiving a relay physical downlink control channel (R-PDCCH) at a relay in a wireless communication system is discussed. The method according to one embodiment includes receiving first control information for downlink scheduling in a first slot of a set of resource block (RB) pairs. The first control information includes allocation information on one or more resource units. The method according to the embodiment further includes monitoring second control information in a second slot of the set of RB pairs. If the R-PDCCH is assigned to the second slot of the set of RB pairs, the R-PDCCH is configured to carry control information for uplink scheduling.

Abstract: A method and a first base station are described for setting measurement resources. Information about setting of a blank subframe of a second base station among a plurality of subframes is received. Resources are set in which a terminal will perform measurement using the information about setting of the blank subframe of the second base station. The information about setting of the blank subframe of the second base station includes a bitmap indicating blank subframes and non-blank subframes of the second base station. In addition, the resources in which the terminal will perform measurement are determined among the blank subframes indicated by the bitmap.
