Abstract: There is provided a method for acquiring and modifying uplink and downlink synchronization, by which, if there is a possibility of ISI occurring due to incorrect downlink synchronization of a terminal with a base station, the terminal receives a ranging response from the base station, modifies incorrect downlink synchronization, and acquires uplink synchronization in accordance with modified downlink synchronization. The method for acquiring and modifying uplink and downlink synchronization efficiently prevents, in a cooperative communication network, discrepancy in signal transmission synchronization between the base stations, excessive attenuation of a transmitted signal, or a delay caused by a difference in reflection paths.
Abstract translation: 提供了一种用于获取和修改上行链路和下行链路同步的方法，通过该方法，如果由于具有基站的终端的下行链路同步不正确而发生ISI的可能性，则终端从基站接收测距响应，修改 不正确的下行链路同步，并根据修改的下行链路同步获取上行链路同步。 用于获取和修改上行链路和下行链路同步的方法在协作通信网络中有效地防止了基站之间的信号传输同步的差异，发射信号的过度衰减或由反射路径的差异引起的延迟。

Abstract: The present invention relates to a data transmitting method using a bandwidth request channel and a user terminal and a base station conducting the same. The present invention provides a communication method by a user terminal which transmits data to a base station via a bandwidth request channel, including: generating a preamble for bandwidth request; determining whether a message for the bandwidth request is generated; generating a first signal value to be operated with the preamble when it is determined that the message is generated and generating a second signal value to be operated with the preamble when it is determined that the message is not generated; operating the preamble with the generated first signal value or second signal value; and transmitting a signal including the operated preamble to the base station, thereby reducing overhead occurring when the bandwidth request information is demodulated.
