FIELD: information technology.
SUBSTANCE: invention describes methods of sending data traffic and control information in a wireless network. In one configuration, a transmitter (e.g., node B or UE) can perform beam formation for sending data traffic on M layers based on a precoding matrix, where M can greater than or equal to 1. The transmitter can also perform beam formation for sending control information on up to M layers based on the same precoding matrix which was used for data traffic. The transmitter can send data traffic with the formed beam pattern over a first physical channel and can send the control information generated on the beam pattern over a second physical channel. The transmitter can multiplex data traffic with the formed beam pattern and control information with the formed beam pattern using time-division multiplexing (TDM) or frequency-division multiplexing (FDM).
EFFECT: efficient and reliable transmission of control information in order to achieve high throughput.
