    摘要: A method for performing ranging in a broadband wireless access system including a user equipment and a base station and using multi-carrier is described. A method using a structure in which a length of a part occupied by a ranging sequence is extended in the time domain includes a method using a structure in which a preamble occupied by the ranging sequence is repeated three times or more, a method using a structure in which a length of a preamble occupied by the ranging sequence is extended in the time domain, and a method using a structure in which lengths of a cyclic prefix and/or a guard time in the time domain are designed in consideration of a delay spread of a channel and a trip delay. Even in a cell structure having an extended radius, the trip delay can accurately be estimated.

    摘要: A method for establishing a cyclic shift sequence to provide against the frequency offset is disclosed. The method calculates a distance between a channel response position of the sequence and an alias channel response position caused by a frequency offset, calculates the number of cyclic shifts per group according to the calculated distance, and establishes the cyclic shift (CS)-applying interval. This method easily establishes a cyclic shift (CS) interval at a specific location having no overlapping by considering a channel response of a reception (Rx) sequence and an alias location of this reception (Rx) sequence, although a reception (Rx) signal is shifted by a channel delay spreading or a propagation delay irrespective of categories of a domain generating a sequence, so that it can greatly reduce the number of the detection errors and the false alarm rate. And, if a sequence of the cyclic shift (CS) is allocated to a cell having a frequency offset of more than a predetermined level, the present invention can minimize the influence of a frequency offset on a high-mobility cell.
