RANGING METHOD USING NEW RANGING STRUCTURE |
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. |
