Abstract
The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate, after a 4G communication system such as an LTE system. The present invention relates to a method for guaranteeing a quality of a service in a wireless communication system. Specifically, a method for a base station according to an embodiment of the present invention comprises the steps of: receiving a PRACH from a terminal; identifying a transmission pattern of the PRACH for a symbol group including a plurality of symbols transmitted in a single tone; acquiring information of phase difference between tones, in which the PRACH has been received, according to multiple intervals between symbol groups on the basis of the transmission pattern of the PRACH; estimating a phase offset on the basis of the information of phase difference; and generating uplink timing information for transmission to the terminal, by using a timing offset converted from the estimated phase offset.
