Abstract

In a mobile communication system, an advanced mobile station (AMS) transmits a message to an advanced base station (ABS). The message includes an indication of whether the AMS supports the acoustic antenna switching scheme. If the information indicates that the AMS supports the sonic antenna switching scheme, the message including the information includes information indicating the antenna configuration that the AMS expects to use in the sonic antenna switching operation.

Description

technical field [0001] The present invention relates to an apparatus and method for operating a sonic antenna switching scheme in a mobile communication system. Background technique [0002] In an Institute of Electrical and Electronics Engineers (IEEE) 802.16m communication system which is a typical example of a mobile communication system, a sounding channel signal is used to effectively use a beamforming (BF) scheme in a downlink (DL) and Multi-User Multiple-Input Multiple-Output (MU-MIMO) schemes. The sounding channel is an uplink (UL) channel, and a sounding channel signal is transmitted via each of a plurality of transmission antennas used by an advanced mobile station (AMS). An Advanced Base Station (ABS) may estimate a DL channel state for the AMS based on a sounding channel signal transmitted through each of the transmission antennas of the AMS. If an AMS with the same number of transmit and receive antennas (that is, with N transmit and N receive antennas) transm...
