Method and apparatus for controlling transmission of data packet in mobile telecommunication system

The present invention relates to a method and apparatus for selectively request the retransmission of packets in that, the link adaptation scheme and the ARQ scheme of the method for adapting a mobile communication system in the state of the channel. If the received power value measured for the forward pilot channel is larger than a first threshold terminal checks a packet error in decoding the current packet. If there is no error, the test results to stop the retransmission of the current packet with the error, it requests retransmission of the current packet. In addition, the received power value of the second than the threshold when the value is smaller than is now given up transmission of the packet or request the base station to re-transmit from the beginning of the current packet, and the received power value of the first threshold value is less than or equal to a second threshold If equal to or shall request the retransmission of the current packet. Thus the invention may also reduce storage requirements of the transmitter in accordance with the decrease return time not only increases the throughput of the channel to reduce the decoding and error checking in accordance with the power consumption.
