Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and to an apparatus for transmitting an SRS in a multi-antenna system. The method comprises the steps of: acquiring specific information for discriminating a first antenna group and a second antenna group from among a plurality of antennas, wherein said first antenna group includes one or more antennas which are set to a turned-on state to perform communication with a base station, and said second antenna group includes one or more other antennas which are set to a turned-off state; transmitting an SRS to the base station if a predetermined condition is satisfied, under the condition that the second antenna group is set to the turned-off state; and setting the second antenna group to a turned-off state after the transmission of the SRS.

Abstract: A method and a user equipment for transmitting control information in a communication system are discussed. The method according to an embodiment includes multiplying a transmission information symbol s for the control information by a frequency direction sequence c(k) to generate a first output sequence s(k), where s(k)=s*c(k), k=0, . . . , Nk−1, and Nk corresponds to a number of subcarriers included in a resource block allocated for an uplink control channel; multiplying the first output sequence s(k) by a time direction sequence x(n) to generate a second output sequence s(k, n), where s(k, n)=s(k)*x(n), n=0, . . . , Nn−1, and Nn corresponds to a number of symbols used for transmission of the control information in a transmission time interval; and transmitting the second output sequence s(k, n) through the uplink control channel in the transmission time interval.

Abstract: A method of mapping a physical resource to a logical resource in a wireless communication system is described. The method includes dividing a physical frequency band into at least one frequency partition. Each frequency partition is divided into a localized region and a distributed region in a frequency domain. The method further includes mapping the at least one frequency partition into at least one logical resource unit. The localized region is directly mapped into the logical resource unit and the distributed region is mapped into the logical resource unit after rearranging subcarriers within the distributed region.

Abstract: A method is provided for transmitting an uplink (UL) control signal in a carrier aggregation (CA) system including a plurality of UL component carriers (CCs). A user equipment (UE) determines whether a simultaneous transmission of a physical UL control channel (PUCCH) and a physical UL shared channel (PUSCH) is configured. If the simultaneous transmission of the PUCCH and the PUSCH is not configured, the UE determines whether the PUSCH is scheduled in a primary CC (PCC) or in any secondary CCs (SCCs) of the CA system. If the PUSCH is not scheduled in the PCC, but is scheduled in the any SCCs, the UE selects one SCC from the any SCCs in which the PUSCH is scheduled according to a priority which is set by higher layer signaling. The UE piggybacks and transmits a UL control information (UCI) of the PCC on the PUSCH of the selected SCC.
