摘要： A method for reducing inter-cell interference and a method for transmitting a signal by a collaborative MIMO scheme, in a communication system having a multi-cell environment are disclosed. An example of a method for transmitting, by a mobile station, precoding information in a collaborative MIMO communication system includes determining a precoding matrix set including precoding matrices of one more base stations including a serving base station, based on signal strength of the serving base station, and transmitting information about the precoding matrix set to the serving base station. A mobile station in an edge of a cell performs a collaborative MIMO mode or inter-cell interference mitigation mode using the information about the precoding matrix set collaboratively with neighboring base stations.

摘要： A method for specifying a transport block-to-codeword mapping relationship and a method for transmitting a downlink signal using the same are described. If a swap flag has a first logic value, a first transport block is mapped to a first codeword and a second transport block is mapped to a second codeword. If the swap flag has a second logic value, the first transport block is mapped to the second codeword and the second transport block is mapped to the first codeword. If the size of any one of two transport blocks is 0, the swap flag is not used.

摘要： The present invention relates to a method for transmitting an uplink reference signal in a multi-node system and a terminal using same. The method comprises the steps of: receiving a synchronization signal from a node; receiving parameters for a virtual cell identifier(ID) from the node; generating an uplink demodulation reference signal(DM-RS) using the parameters for the virtual cell ID; and transmitting the generated uplink DM-RS to the node, wherein a physical cell ID is a cell ID obtained from the synchronization signal, and the parameters for the virtual cell ID are parameters used for generating the uplink DM-RS in the replacement of the physical cell ID.
