Abstract:
A MIMO communication method for performing MIMO communication between a base station including a plurality of antennas, and a plurality of terminals accommodated in the base station. The method includes, in the base station, dividing the plurality of terminals into a first and a second group, and assigning orthogonal codes with each other to the respective groups, spreading transmission data to the plurality of terminals with the assigned codes, multiplying data obtained by the spreading by a predetermined pre-coding matrix, obtaining a channel matrix representing channels between the plurality of antennas and the plurality of terminals, multiplying data obtained by the multiplying by the pre-coding matrix by a complex conjugate matrix of the channel matrix, and transmitting data obtained by the multiplying by the complex conjugate matrix from the plurality of antennas.

Claim (Index 4):
The MIMO communication method according to  claim 1 ,\n wherein the plurality of terminals are configured to transmit reference signals to the base station, the base station is configured to measure reception time differences between the plurality of terminals, gives a notification of the time differences of the transmission time to each of the terminals, and each of the terminals is configured to change transmission timing of the own transmission signal in accordance with the notification.
