METHOD FOR TRANSMITTING DATA IN MULTIPLE ANTENNA SYSTEM

摘要

PURPOSE: A method for transmitting data in a multiple antenna system is provided to simultaneously support a terminal supporting a 4Tx MIMO technique and a terminal supporting a 8Tx MIMO technique. CONSTITUTION: A base station transmits a channel estimation signal(S110). The channel estimation signal includes the first pilot for channel estimation of the first terminal supporting a multiple antenna and the second pilot for channel estimation of the second terminal supporting a larger number of antennas than the first terminal. The terminal receives a signal for the channel estimation to perform channel estimation(S120). The terminal transmits feedback data to the base station(S130). The first pilot is transmitted about a multiple antenna that the second terminal supports in a linear combination form.
