Abstract: Disclosed are a method for dividing a transport block of a low density parity check (LDPC) code and an apparatus therefor. A method for dividing a transport block of an LDPC code according to the present disclosure can improve the performance of the LDPC code by dividing the transport block using a minimum number of code blocks. In addition, it is possible to minimize shortening bits by making the size of some of the code blocks smaller than the size of the other code blocks. Further, it is possible to prevent performance degradation due to a minimum size code block by minimizing the number of the code blocks and performing shortening on a large size code block.

Abstract: A method and apparatus for performing uplink (UL) transmission in a wireless communication system is provided. A second user equipment (UE) wakes up for transmission of UL data, searches a first UE which is capable of downlink (DL) transmission to the second UE, acquires information for transmission of the UL data, and transmits the UL data to a network by using the acquired information. The second UE may only be capable of UL transmission to the network and may not be capable of DL reception from the network. Alternatively, the second UE may be capable of UL transmission to the network and may be capable of synchronization from the network.
