Cooperative network with adaptive retransmission request strategy

摘要

The method involves determining whether a transmission channel routing a data packet between two nodes is in an outage state. The packet is retransmitted by using a different transmission resource or a modulation and coding scheme with lower spectral efficiency in the preceding transmission of the packet if the channel is in the outage state. The packet is retransmitted by using the same transmission resource used by same node in the preceding transmission of the packet if the channel is not in the outage state.
