Single user super position transmission for future generation wireless communication systems

Abstract

A base station device can transmit data via multiple data channels to a single user equipment device. Each of the multiple data channels can be configured and scheduled via respective downlink control channels to the user equipment device. In an embodiment, the downlink control information and data can be processed in the transmitter via separate coding structures, and then the separate channel data can be combined for transmission to the mobile equipment. The data channels can use overlapping resource elements, and the receiver can use interference cancellation to remove interference from the subsequent data channel after decoding the data from the first data channel. In other embodiments, the data channels can be associated with different beamforming matrices, demodulation reference signal ports, constellation points and resource elements.
