摘要： An adaptive and scalable packet error correction apparatus and method in a wireless multicast network is provided. Each retransmission request from a receiver contains a round number and the number of repairs sent in that round. At each receiver, there are two counters for counting the rounds sent out on the network and the number of repairs that have been required. A receiver on the wireless multicast network listens to the ARQ requests sent by other receivers to update the two counters and determines whether its request should be suppressed or be sent out.

摘要： The invention is related with network communication, in particular wireless networking. In order to improve bandwidth utilization, a header compression protocol is implemented in most wireless network systems, such as robust header compression ROHC for WLAN systems. When using multicast groups for data communication problems with ROHC are related with relative late initiation of stations that newly enter the multicast group. The invention proposes an improved state machine for the compressor in order to overcome this drawback. It is also proposed an improvement for the decompressors which omit sending positive acknowledgements in order to further improve compression efficiency. The invention also concerns an accordingly improved method for the exchange of data packets in a network of distributed stations.
