Disclosed herein are apparatuses, systems, and methods for reference signal design for initial acquisition, by receiving a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS) from a first transmit (Tx) beam, in first contiguous orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A UE can receive at least a second PSS and a second SSS from a second Tx beam in contiguous OFDM symbols of the downlink subframe. A UE can then detect beamforming reference signals (BRSs) corresponding to the first Tx beam and the second Tx beam, based on identification of physical cell ID information and timing information processed from the first PSS, the second PSS, the first SSS, and the second SSS. The UE can select the first Tx beam or the second Tx beam that was received with the highest power, based on the BRSs. Other embodiments are described.

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.
