摘要： A method of transmitting data using HARQ includes transmitting a first block, a partial bit stream of a codeword, and transmitting a second block, a bit stream starting from a bit index next to the last bit index of the first block, according to a retransmission request with respect to the codeword, wherein a different modulation scheme from that of the first block is applied to the second block. A coding gain of an incremental redundancy (IR) mode can be obtained although the amount of retransmission data is arbitrarily changed according to a change in transmission attributes such as a modulation scheme, resource allocation, the size of a transport block, or the like, in the adaptive HARQ scheme, so the transmission efficiency of a system can be enhanced.

摘要： A method for efficiently transmitting downlink control information is described. A method for transmitting control information in a multiple antenna system which can simultaneously transmit a maximum of two codewords includes transmitting modulation and coding scheme (MCS) information, a new data indicator (NDI) and a redundancy version (RV) for information blocks transmitted through the two codewords, and transmitting additional control information including at least one of a swapping indicator and enable/disable information. The swapping indicator indicates whether or not swapping occurs between the information blocks transmitted through the two codewords, and the enable/disable information indicates whether or not any one of transmissions through the two codewords is disabled. The swapping indicator is reserved when any one of transmissions through the two codewords is disabled, thereby reducing signaling overhead and efficiently transmitting necessary information.

摘要： A data rate matching method is disclosed. More particularly, a rate matching method using at least two parameters is disclosed. The rate matching method includes selecting bits from an input bitstream using a primary- indication parameter for selecting at least one bit and a secondary indication parameter for canceling the selection using the primary indication parameter or additionally selecting unselected bits, and processing the selected bits according to a rate matching mode so as to generate an output bitstream. By using the rate matching method, high¬ speed processing is realized by a simple calculation and the locations of target bits can be efficiently decided using at least two indication parameters. Accordingly, it is possible to reduce a calculation amount or improve performance.
