摘要： PROBLEM TO BE SOLVED: To provide a method for constructing and allocating an RACH preamble according to a cell radius of a base station irrespective of a length of a guard time (GT).SOLUTION: A method for transmitting an RACH preamble comprises the steps of: receiving, by user equipment, information that is associated with predetermined preambles for a random access, from a base station; and transmitting, by the user equipment, an RACH preamble selected from the predetermined preambles according to the information, to the base station. The RACH preamble has a preamble format defined by a time-length value of a predetermined CP and either a time-length value of a first sequence or a second sequence, the time-length value of the second sequence is two times the time-length value of the first sequence, and the selected RACH preamble is configured only with the predetermined CP and either the first sequence or the second sequence without a time length of a guard time.
