A wireless communication system is disclosed. A method for constructing a RACH preamble according to a cell radius of a base station (BS) irrespective of a guard time (GT) and a method for allocating the RACH preamble are disclosed. A method for constructing a preamble of a random access channel (RACH) includes acquiring time-length information of a predetermined cyclic prefix (CP) for each cell radius of a base station (BS), acquiring sequence time-length information of a single sequence or a repeated sequence, and constructing the preamble using the predetermined CP time-length information and the sequence time-length information, irrespective of a time length of a guard time (GT).

According to the protocol, Preble Format1, Format2, and Format3 can be configured when they are greater than 14.5 and less than 29.5 KM, Usually, the rationale suggests using Format 1, but due to the complexity of the current network environment, the RACH KPI performance indicates which configuration is better for the current network area traffic model.
