APPARATUS AND METHOD FOR UPLINK CHANNEL SOUNDING IN A WIRELESS COMMUNICATION SYSTEM

摘要

An uplink channel sounding apparatus and method in a wireless communication system are provided, in which in an MS, a baseband MODEM generates as many channel sounding signals as the MS has antennas and outputs the channel sounding signals to an antenna switch. The antenna switch switches the channel sounding signals to the antennas in a one-to-one basis transmitting the channel sounding signals to a BS through all of the antennas of the MS.
