BEAMFORMING OF CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM

Japanese Patent JP2012151859

A

To provide techniques for sending traffic data and control information in a wireless communication system.

A transmitter may perform beamforming to send traffic data on M layers based on a precoding matrix, where M may be one or greater. The transmitter may also perform beamforming to send control information on up to M layers based on the same precoding matrix used for the traffic data. The transmitter may send the beamformed traffic data on a first physical channel and may send the beamformed control information on a second physical channel. The transmitter may multiplex the beamformed traffic data and the beamformed control information using time division multiplexing or frequency division multiplexing.
