METHOD OF CONSTRUCTING RANDOM ACCESS CHANNEL (RACH) PREAMBLE AND METHOD OF TRANSMITTING RACH SIGNAL Russian patent published in 2013 - IPC H04B7/26 

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.
