Abstract:
1. A method for performing point-to-multipoint data transmission from a transmitting station to a plurality of receiving stations, the method comprising the steps of: transmitting data from the transmitting station to the plurality of receiving stations via a first communication channel; performing a first channel switching in the transmitting station when decoding of the transmitted data fails at a receiving station of the plurality of receiving stations, from the first communication channel to a second communication channel; and retransmitting the data via the second communication channel while the first communication channel remains in use for transmitting new data: wherein multiple retransmissions automatically occur on a plurality of different predetermined channels until the data is successfully transmitted via one of the plurality of different predetermined channels, and wherein additional data is simultaneously transmitted on the first communication channel during the multiple retransmissions; and wherein after the decoding of the transmitted data fails at the receiving station, the receiving station automatically establishes a connection for retransmission on a channel of the plurality of predetermined channels without causing notification messaging to occur between the receiving station and the transmitting station.
