Abstract: A method and a base station (BS) for transmitting a signal, and method and a relay for receiving a signal in a wireless communication system are discussed. The method for transmitting a signal according to an embodiment includes mapping a reference signal to a subframe comprising a first slot and a second slot. Each of the first and second slots includes a plurality of resource elements over which the reference signal is allowed to be mapped. When a last orthogonal frequency division multiplexing (OFDM) symbol of the subframe is not available for a BS-to-relay transmission, the reference signal is not mapped to the second slot and a data signal is mapped to the resource elements of a penultimate OFDM symbol of the second slot. The method further includes transmitting the reference signal to a relay.

Abstract: A method and apparatus for allowing a UE to transmit uplink signals using a MIMO scheme are disclosed. In order to maintain good Peak power to Average Power Ratio (PAPR) or Cubic Metric (CM) properties when the UE transmits uplink signals using the MIMO scheme, the UE uses a precoding scheme based on a precoding matrix established in a manner that one layer is transmitted to each antenna in specific rank transmission.

Abstract: A method is provided for receiving a downlink signal at a downlink reception entity in a wireless communication system. Downlink control information is received by demodulating a Physical Downlink Control Channel (PDCCH) in a first resource block (RB) pair within an RB bundle by using a first Demodulation Reference Signal (DMRS) in the first RB pair. Further, downlink data is received by demodulating a Physical Downlink Shared Channel (PDSCH) in one or more second RB pairs within the RB bundle by using a second DMRS in the one or more second RB pairs. The second DMRS is used based on an assumption that a same precoder is applied to the one or more second RB pairs.
