A method and system provides for efficient data throughput by avoiding unnecessary data sub-packets transmission while not missing new data packets. The method and system distinguishes between a sub-packet for a current data packet and a sub-packet for a new data packet by assigning different codes to them. When a currently received sub-packet and a previously received sub-packet for a previously decoded data packet have equivalent codes, the remote station sends (506) an acknowledgement signal to the base station, preventing unnecessary sub-packets transmission. When the currently received sub-packet and the previously received sub-packet have different codes, the remote station sends (510) an acknowledgement signal, if the remote station can decode the new packet from the current sub-packet. Otherwise, the remote station sends (516) a negative acknowledgement signal to the base station, and requests more sub-packs for the current packet if the limit on number of transmission for currently received sub-packet has not reached. |
