Method and system for transmitting packet data by using plural number channel automatic repeat request for use in portable internet network

The invention The present invention relates to a packet data transmission method and system using a multi-channel automatic retransmission request from the portable Internet network. The present invention includes the steps of determining a transmission packet scheduled by (a) the packet data when the packet data is generated to be transmitted to a plurality of packet PSS packing (Packing) and select any one of the packets of the multiple packets; (B) separating the traffic (Traffic) channels assigned to the PSS of a plurality of logical channels (Logical Channel) to the timer for transmission and a logical channel for transmitting scheduled packets to the PSS through any of the logical channels of the plurality of logical channels the step of operating; (C) the PSS is confirmed whether or not the packet is received and transmitted to the RAS through a logical channel, receiving a packet generates a verification signal in response to the check result; And (d) determining whether the RAS determines whether it has received a confirmation signal confirming determine the transmission packet scheduled according to the result and whether the transmission all of the plurality of packets; And (e) (d) determination results, the number that have not transmitted all the packets, the packet data transmission method using a multi-channel ARQ from the portable Internet network, characterized in comprising the step of proceeding to step (b) of to provide. According to the present invention, in a radio environment in which an error occurs frequently, reducing the excessive occurrence of the retransmission it can improve the convenience of the error control performance and system implemented by performing only the retransmission of the same packet.
