Abstract: A method for transmitting and receiving system information in a communication system is disclosed. An operation method of a UE comprises the steps of: checking minimum system information included in an SS/PBCH block received from a base station; receiving a PDCCH in a control resource set indicated by the minimum system information; checking a time-frequency resource through which a PDSCH including RMSI is to be transmitted, on the basis of scheduling information included in the PDCCH; and acquiring the RMSI from the PDSCH received in the time-frequency resource. Therefore, the performance of the communication system can be improved.

Abstract: A method for transmitting and receiving a synchronization signal in a communication system is disclosed. An operation method of a terminal comprises the steps of: receiving, from a base station, a synchronization signal and an SS block including a PBCH; estimating y bits among x bits for indicating a number of a system frame on which the SS block has been transmitted, on the basis of a sequence used for the scrambling of the PBCH included in the SS block; decoding the PBCH included in the SS block so as to acquire z bits among the x bits for indicating the number of the system frame on which the SS block has been transmitted; and confirming the number of the system frame on the basis of the y bits and the z bits. Therefore, the performance of a communication system can be improved.

Abstract: Provided is an LDPC (Low Density Parity Check) code for terrestrial cloud broadcast. A method of encoding input information based on an LDPC (Low Density Parity Check) includes receiving information and encoding the input information with an LDPC codeword using a parity check matrix, wherein the parity check matrix may have a structure obtained by combining a first parity check matrix for an LDPC code having a higher code rate than a reference value with a second parity check matrix for an LDPC code having a lower code rate than the reference value.
