Title:
DISTRIBUTED RETRANSMISSION METHOD BASED ON SUPERPOSITION CODED MODULATION IN MULTIHOP RELAY NETWORK
Document Type and Number:
WIPO Patent Application WO/2010/048748
Kind Code:
A1
Abstract:
A distributed retransmission method is proposed in present invention. The method includes the following steps: Base Station (BS) broadcasts Superposition Coded Modulation (SCM) data bursts to Relay Station (RS) and the first Mobile Station (MS), wherein the SCM data bursts are composed of the superposition of the first coded modulation data bursts which can be supported by transmission channel from BS to the first MS and the second coded modulation data bursts which can be supported by transmission channel from BS to RS, wherein the destination of the second coded modulation data bursts may be the first MS or the second MS in multi-user transmission mode; RS judges whether the first MS has correctly decoded the first coded modulation data bursts, and also judges the channel condition between RS and the first MS, then determines RS retransmission scheme according to the judgments. The retransmission scheme based on SCM proposed in present invention enables the retransmission time delay to be decreased and the cell throughput and capacity to be increased.
