UE DATA TRANSMITTING METHOD AND APPARATUS USING CELL SEARCH SIGNAL IN SYNCHRONIZED CELLULAR SYSTEM

摘要

Provided are a method and apparatus for transmitting data using cell search signals in a mobile station. In a cellular system in which base stations are synchronized with each other, a mobile station determines its own location, using cell search signals that are received from base stations of a home cell and a neighboring cell, and estimates uplink delay time information. Thus, a RACH burst needs not to be transmitted, uplink delay time errors can be reduced, and accordingly, a guide period (GP) of an asynchronous RACH burst which is used to measure an uplink delay time can be shortened. Also, the mobile station can more accurately acquire its own location by receiving cell search signals from three or more base stations.
