    Abstract: A base station apparatus for transmitting a reference signal in a wireless communication system is provided in which a processor generates the same sequence for resource elements (REs) allocated to each layer for reference signal transmission and spreads or covers Walsh codes for a user equipment-specific reference signal sequence such that sequences generated for the REs can be orthogonal to each other on a time axis. The Walsh code spreading or covering by the processor is applied on a frequency axis based on a plurality of resource blocks (RBs) or based on a pair of RBs such that mutually different sequences having mutually different sequence values can be mapped between RBs or between pairs of RBs. A transmission module transmits the reference signal, to which the generated reference signal sequence is applied to user equipment via each layer.

    Abstract: A method for transmitting a downlink signal in a wireless mobile communication system. The method according to one embodiment includes generating a resource indication value (RIV) indicating a start index (S) of consecutive virtual resource blocks (VRBs) and a length (L) of the consecutive VRBs; transmitting downlink control information including resource block allocation information. The downlink control information is common information for plural users, and the resource block allocation information includes the RIV. The method according to the embodiment further includes transmitting the downlink signal on the consecutive VRBs. If Y−1≦└X/2┘, then the RIV is defined by RIV=X(Y−1)+Z, else the RIV is defined by RIV=X(X−Y+1)+(X−1−Z), where X=└NVRB/G┘, Y=L/G, and Z=S/G, in which, L is the length of the consecutive VRBs, S is the start index of the consecutive VRBs, NVRB is the number of VRBs, L is a multiple of G, S is a multiple of G, and G is an integer of 2 or higher.

    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.
