Abstract
The present invention, in preferred aspects, provides a communication method using a network coding packet in a wireless network, with reduced occurrence of negative acknowledgements, between a access point and plural mobile terminals. In preferred embodiments of the present invention, a communication method using a network coding packet in a wireless network comprises: (a) transmitting plural downlink multicast packets, each containing serial numbers of packets, to the first and second mobile terminals sequentially; (b) receiving a first negative acknowledgement from the first mobile terminal; (c) receiving a second negative acknowledgement from the first mobile terminal or the second negative acknowledgement skipping the first negative acknowledgement on occurrence of the first packet error at the second mobile terminal; and (d) transmitting a restoration packet containing exclusive OR packet of all errored packets in the restoration period defined in reference to the second negative acknowledgement from the first and second mobile terminals.
