Abstract

A sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal using the multiple antenna technique is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. Moreover, the sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. The sounding reference signal is transmitted through an antenna pattern in which the sounding reference signal can be transmitted through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead in this environment.
