<p><P>PROBLEM TO BE SOLVED: To give the improved property and higher flexibility of a communicating system, by a MIMO system having multiple spatial multiplexing modes. <P>SOLUTION: The communicating system includes (1) a steered mode of a single user which transmits multiple data streams by an orthogonal spatial channel to a single receiver, (2) a non-steered mode of a single user which transmits multiple data streams from multiple antennas to a single receiver without any spatial processing in a transmitter, (3) steered modes of multi-users which transmit multiple data streams to multiple receivers at the same time while being accompanied by a spatial processing in a transmitter, and (4) non-steered modes of multi-users which transmit multiple data streams from multiple antennas to multiple receivers having multiple antennas without any spatial processing in a transmitter. Each spatial multiplexing mode is selected from multiple spatial multiplexing modes supported by the system to the set of the terminal of each user. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
