Ranging method and apparatus in a communication system with relay station, and system thereof |
摘要 |
A method for performing ranging by a mobile station in a communication system. The method includes transmitting a ranging sequence to a relay station; receiving an added signal of a reference sequence of the relay station and the ranging sequence, from the relay station; performing a correlation operation on each of the ranging sequence and the reference sequence in the added signal; estimating a time difference between the ranging sequence and the reference sequence depending on the correlation operation; and transmitting the signal to the relay station taking the time difference into account.
