Abstract: A quasi-cyclic low density parity check (QC LDPC) code rate matching method is disclosed. According to the rate matching method in the present disclosure, the minimum lifting value can be selected from among lifting values by which a codeword longer than a target code block can be generated. A coding gain through retransmission can be acquired by generating the codeword that is longer than the target code block. In addition, by selecting a lifting value of a proper magnitude, rate matching for information bit sequences of various lengths can be performed.

Abstract: Provided are an apparatus and a method for allocating resources in a wireless communication system. In particular, the present invention includes the feature of alternately allocating resources for D2D communication and resources for cellular communication, or allocating resources of a D2D link to not be adjacent to each other. In addition, the present invention prevents interference with the cellular communication and interference with other D2D links by allocating a partial area of the resources allocated for the D2D communication to an area for transmitting a D2D uplink symbol to an eNB, or by adding a GP symbol to a partial area of the resources for the D2D communication. Furthermore, in the case of applying a TDD scheme, the present invention prevents interference with symbols for performing the cellular communication by defining a partial section of a special subframe as a section for transmitting the D2D uplink symbol, or by reflecting a time delay of N OFDM symbol durations. Accordingly, the present invention prevents the D2D communication from causing interference.
