摘要： A method for transmitting and identifying a transmit power value in a multi-user MIMO scheme is disclosed. The transmit power value transmission method includes calculating available transmit power ratios for respective layers, reducing a number of bits used to represent entire transmit power ratio values by allocating same bit value to a plurality of same transmit power ratio values among the calculated transmit power ratio values for the respective layers; quantizing a transmit power ratio values of symbols to be transmitted to the UE using the entire transmit power ratio values of the reduced number of bits; and transmitting the quantized transmit power ratio values to the UE.

摘要： In a mobile communication system using both a discontinuous transmission scheme and a compressed mode transmission scheme, if a preamble and/or a postamble of a channel including control information for transmitting a specific channel overlaps a compressed mode (CM) gap, an overall transmission unit is not transmitted or remaining signals of the transmission unit excluding the preamble and/or the postamble overlapping the CM gap are transmitted.

摘要： A method for indicating a combination between a codeword and a layer in a MIMO communication, system, a layer mapping method, and a data transmission method using the same are disclosed. A minimum number of codeword-layer mapping combinations from among all available combinations based on the numbers of all codewords and all layers are pre-defined in consideration of a ratio of a codeword to a layer, a reception performance of a receiver, and reduction of combinations, so that a data transmission method using the predefined combinations is implemented. If a specific one codeword is mapped to at least two layers, a diversity gain can be acquired.
