TRANSMITTER AND RECEIVER DEVICES AND METHODS THEREOF

摘要

A data transmission and signaling method in a transmitter device configured for concurrent transmission of non-orthogonal independent downlink data streams to receiver devices in a wireless communication system comprises sending to all receiver devices control information that includes indices of receiver devices selected for transmission, code rates of selected receiver devices, a label bit-to-receiver device allocation, an index of an expanded constellation, and a number of resource elements used for transmission.
