    摘要: A method for receiving control information for data reception at a specific user equipment in a communication system in which at least one data transmission mode is used to transmit data of the at least one UE is disclosed. The method receives the control information including a first field and a second field, in which the first field indicates a data transmission mode of the specific user equipment (UE) and the second field indicates a resource block via which the data is transmitted, and receives the data by decoding the control information. As a result, a method for constructing control information required for receiving control data of a localized-mode UE and a distributed-mode UE can be recognized.

    摘要: A method of encoding data using a parity check matrix, a method of decoding encoded data, and a data retransmission method using the same are disclosed. A data retransmission method in a communication system includes transmitting a codeword encoded by a first parity check matrix corresponding to a first coding rate, among at least two parity check matrixes corresponding to different coding rates, receiving NACK from the receiver in response to the codeword, and transmitting parity bits encoded by some of the second parity check matrix corresponding to a second coding rate, among the at least two parity check matrixes, to the receiver.

    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, highspeed 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.
