摘要
A two-way relay wireless communication method and device may combine multiple bit steams, for one source node and two target nodes, and broadcasting a network coded combined bit sequence to reduce the number of time slots for transmission. A first device may receive a signal from the source node and a target node simultaneously in a time slot. The first device may receive subsequent signals from the source node and multiple target nodes simultaneously in successive time slots. Hierarchical modulation may be applied to the received signals. The first device may decode the received signals and generate a plurality of intermediate bit sequences (IBS)s for a broadcast transmission. The generated IBSs may be grouped according to a channel condition. A second device may be configured to receive the broadcast transmission and decode a portion of the broadcast transmission that is intended for the second device.
