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.
