Abstract :
New ARQ protocols with spectral efficient acknowledgement and retransmission traffic for reliable point-to-multipoint communication are introduced. One key feature of the proposed algorithms is the simultaneous transmission of negative acknowledgements. In combination with adaptive antennas selective retransmission for broadcast traffic considering the radio channel conditions becomes possible. Performance results for the HIPERLAN/2 system show the benefit of the new algorithms
