Abstract
Network coding in automatic receipt request (ARQ) functionality is disclosed. A compatible transmitter configures a new transmission period, in which the set of data for transmission is transmitted, and a retransmission period, after the new transmission period, in which a number of network coded data is retransmitted based on the acknowledgement feedback received from the receivers receiving the transmitted set of data. The acknowledgement feedback identifies one or more data requested for retransmission by one or more of the receivers. The transmitter determines a number of network coded data that could be transmitted to accommodate each of the requesting receivers and the data requested by such receivers for retransmission. These network coded data would then be retransmitted by the transmitter during the retransmission period.
