DATA TRANSMISSION METHOD, WIRELESS COMMUNICATION SYSTEM, DESTINATION NODE AND RELAY NODE

摘要

The present invention provides a data transmission method, wireless communication system, destination node and relay node. The method includes: the destination node receives the data transmitted by at least one source node at the current time slot; the data transmitted by the at least one source node is demodulated and decoded to obtain a decoding result; after a first relay node demodulates and decodes the data transmitted by the at least one source node and received at the current time slot, the decoding result transmitted by the first relay node is received; the destination node informs, according to the decoding result of demodulating and decoding the data of the source node and the decoding result of the first relay node, the source node to retransmit the data or transmit the new data at the next time slot. The embodiment of the present invention enables the source node to transmit the data at any one time slot and utilizes the channel resources sufficiently, thereby avoiding the waste of the channel resources.
