Abstract:
1. A method for allocating a sounding channel in a wireless communication system which supports a first system and a second system, wherein the first system is a legacy system and the second system is an advanced system of the first system, the method comprising: transmitting first sounding channel allocation information for a first sounding channel for a first system; transmitting second sounding channel allocation information for a second sounding channel for a second system; allocating the first sounding channel for the first system to an orthogonal frequency division multiple access (OFDMA) symbol in a first zone for the first system based on a unit of a sounding subband using the first sounding channel allocation information; and allocating the second sounding channel for the second system to the OFDMA symbol in a second zone for the second system based on the unit of the sounding subband using the second sounding channel allocation information, wherein the first and second zones are multiplexed in a frequency division multiplexing (FDM) manner, and wherein the sounding subband includes 72 continuous subcarriers.
