Abstract: In a wireless communication system, a physical broadcast channel (PBCH) is encoded based on a Polar code and then is transmitted. Half-frame information within the PBCH is mapped to a bit position 247 among bit positions of the Polar code and synchronization signal and PBCH block (SSB) index information within the PBCH is mapped to bit positions 253, 254, and 255 of the Polar code.

Abstract: A method and device for receiving downlink data in a wireless communication system are discussed. The method performed by a terminal includes receiving, from a base station, first downlink control information through a physical downlink control channel (PDCCH) or a short PDCCH (sPDCCH), wherein the first downlink control information schedules a plurality of short physical downlink shared channel (sPDSCH) regions based on a first transmission time interval (TTI)-based radio frame structure, and each of the plurality of the sPDSCH regions is included in a different plurality of short subframes based on the first TTI-based radio frame structure, respectively; and receiving, from the base station, first downlink data in the plurality of the sPDSCH regions based on the first downlink control information, wherein the first TTI-based radio frame structure has a shorter interval than a second TTI-based radio frame structure for the PDSCH region in which second downlink data is transmitted.

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.
