高速パケットデータシステムの順方向リンクでＭＩＭＯ技術をサポートする送受信装置及び方法

摘要

Methods and apparatus are provided for transmitting and receiving data in a communication system with a plurality of antennas. A method includes informing information related to a transmission time interval for transmission based on a second type reference signal; and transmitting data based on the second type reference signal in the transmission time interval defined by the information related to the transmission time interval for transmission based on the second type reference signal. The transmission time interval defined by the information related to the transmission time interval for transmission based on the second type reference signal is located on a fixed position within a period including a plurality of transmission time intervals.
