Abstract:
1. A method for transmitting data between a transmitter and a receiver, comprising: transmitting packets of data by said transmitter; receiving at the transmitter a feedback message from said receiver, the feedback message including a bitmap block including a predetermined plural number of fields associated with corresponding said packets of data, each field of said fields representing a consecutive identifier corresponding to each packet of the transmitted packets and indicative of a state of acknowledgement of each packet of said packets; associating a timer with a periodic reception of the bitmap block at the transmitter; deactivating said timer after a maximum duration, and then considering said packets associated with said bitmap block to be in an unacknowledged state by said transmitter; and after deactivating said timer, and when at least one packet associated with said bitmap block is in said unacknowledged state, positioning at least some unacknowledged packets associated with said bitmap block in a retransmission queue.
