    摘要: Provided is a method for generating codewords. The method comprises the following steps: receiving an information bit; generating a generating matrix in which a size of a column is identical with a length of the information bit, a size of a row is 24 rows, and values of symbols that are elements of the matrix are 0 or 1; modifying the generating matrix by dividing the generated generating matrix into an upper group and a lower group having an identical size and replacing rows so that the number of symbols having a value of 1 in the upper group is identical with the number of symbols having a value of 1 in the lower group; and obtaining inner products from the information bit and each row of the modified generating matrix and generating codewords from remainders obtained by dividing the inner products by 2.

    摘要: According to the present invention, a source MS, determining initiation of M2M communication or receiving a request for initiating M2M communication from a BS, receives a reference signal for channel quality measurement of a neighboring MS, and the channel quality of the source MS and the neighboring MS is measured by using the reference signal; and information representing the channel quality is transmitted to the BS. Or, the neighboring MS receives a reference signal for channel quality measurement transmitted by the source MS, a channel quality of the source MS and the neighboring MS is measured by using the reference signal, and information representing the channel quality is transmitted to the BS. The BS determines a partner MS for M2M communication with the MS on the basis of a channel quality between the source MS and the neighboring MS.

    摘要: A method including receiving a signal from a terminal; measuring channel state information (CSI); comparing the CSI to determine whether to decode the received signal; and if it is determined to decode the received signal, removing noise by decoding the received signal, and then performing decode and forward (DAF) in which the signal is re-encoded, and if it is determined not to decode the received signal, performing amplify and forward (AAF) in which the received signal is amplified. The CSI may be at least one of a frame error rate (FER), a bit error rate (BER), a signal to noise ratio (SNR), and a signal to interference plus noise ratio (SINR). Accordingly, a time delay consumed for channel decoding in hybrid DAF coordinated communication is decreased, data transmission and resource usage is more effectively achieved in coordinated communication using multiple terminals, and unnecessary power consumption is decreased.
