摘要： A system and method for improving a current wireless communication route, between a source node and a destination node in an on-demand wireless communication network, enables the current communication route to be improved even when the current route has not failed. The method includes analyzing at a local node a packet transmission from the source node, the packet transmission comprising a current route metric (step 705). The local node then determines that it can provide an improved wireless communication route, between the source node and the destination node, having a better route metric than the current route metric (step 710). A route improvement message is then transmitted from the local node to the source node (step 740).

摘要： A radio communication system comprises a communication channel for the transmission of data packets (302) from a primary station having a plurality of antennas to a secondary station having at least one antenna. The channel comprises a plurality of paths, and the primary station transmits a plurality of packets substantially simultaneously. Each of the plurality of packets is transmitted via a different subset of the plurality of paths, for example by arranging for each packet to be transmitted via a different antenna or antenna beam. The secondary station receives the plurality of data packets, determines whether each packet is received correctly and signals this determination (typically as an acknowledgement (304) or a negative acknowledgement (306)) to the primary station for each of the plurality of packets. The signalling may be by any convenient means, for example transmitting each acknowledgement or negative acknowledgement via a different subset of available uplink paths.
