Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. A method for transmitting and receiving data comprises the steps of: receiving a first synchronization block over a first narrow band; identifying whether an indicator indicating that the first narrow band is not allocated to a terminal is included in the first synchronization block; and performing synchronization in the first narrow band if the indicator indicating that the first narrow band is not allocated to the terminal is not included in the first synchronization block.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The method is for phase correction of an antenna in a large-capacity antenna system, the method includes grouping large-capacity antennas into a predetermined number of groups; setting a path such that ports of the grouped antennas have a feedback path; outputting a test signal to be outputted to each antenna port of each group by adding a code or sequence having orthogonality; separating signals for each antenna port in the group by using the code or sequence having orthogonality in a signal received through the feedback path; and calculating a calibration value by detecting a phase change of the separated signal.
