Abstract
FIELD: radio engineering communication.SUBSTANCE: method of constructing a random access channel (RACH) preamble according to a cell radius of a base station (BS) irrespective of a guard time (GT) and a method of allocating the RACH preamble are disclosed. The method of constructing a RACH preamble 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 the time length of a guard time (GT).EFFECT: high transmission capacity.16 cl 13 dwg
