Abstract: Provided are a method and apparatus for allocating a DMRS (DeModulation Reference Signal) port in a wireless communication system. A base station: respectively allocates the DMRS port to a plurality of nodes by the number of layers used in each node; maps the DMRS port allocated to each node to a resource element within a RB (Resource Block); and transmits DMRS through the DMRS port allocated to each node. The plurality of nodes have the same cell ID (identifier) and the DMRS ports allocated to neighboring nodes in the plurality of nodes do not overlap each other.

Abstract: According to one aspect of the present invention, values which are specifically defined for each user equipment are reflected when resource allocation/mapping of downlink/uplink ACK/NACK channels is performed, so as to vary uplink/downlink ACK/NACK information transmitting resources for each user equipment allocated to the same downlink/uplink resource. According to another aspect of the present invention, nodes for transmitting uplink/downlink ACK/NACK information vary for each user equipment allocated to the same downlink/uplink resource. According to the present invention, even when downlink/uplink signals for a plurality of user equipment are transmitted from the same resource, uplink/downlink ACK/NACK signals of the plurality of user equipment are transmitted from different resources, thereby reducing interferences among ACK/NACK signals of the plurality of user equipment.

Abstract: A method of transmitting data in a wireless communication system is provided. The method includes generating duplicate data by using repetition coding, the duplicate data being the same as original data, shifting the phase of the duplicate data, and transmitting the original data and the phase-shifted duplicate data. The duplicate data is mapped to a modulation symbol having a different size or phase as that of the original data, thus to reduce the PAPR unlike the general repetition coding.
