Abstract
The initial transmission of data packets in a point-to-multipoint communication network may often be delayed when retransmissions of erroneously decoded data packets are required. According to an aspect of the present invention, point-to-multipoint data transmission and retransmission of erroneously decoded data from a transmitting station to a plurality of receiving stations is performed, where retransmitted data is sent via at least one communication channel, which is different from the one used for the initially transmitted data. Advantageously, due to this there may be no need for further communication between the transmitting station and the receiving stations. Furthermore, according to an aspect of the present invention, the initial transmission of data packets is not delayed by retransmissions.
