Method and apparatus for controlling packet transmission in a mobile telecommunication system
First Claim
1. A method of controlling transmission of a data packet from an access network (AN) in an access terminal (AT) of a mobile telecommunication system where the AN transmits the data packet in successive time slots, each slot having a plurality of data bits, and the AT receives the data packet from the AN, the method comprising the steps of:
- comparing a received C/I of a forward pilot signal received from the AN with a predetermined first threshold;
selectively checking for errors in the data packet in a received time slot according to whether the received C/I is greater than the first threshold; and
transmitting a signal requesting termination of retransmission of the data packet to the AN if no errors are found in the data packet after said checking.

Abstract
A method of adapting a mobile telecommunication system to channel conditions. To control transmission of a data packet from an access network (AN) in both a link adaptation scheme and an ARQ (Automatic Repeat reQuest) scheme, an access terminal (AT) compares the received power of a forward pilot signal received from the AN with a predetermined first threshold, checks errors in the data packet of a received time slot if the reception power is greater than the first threshold, and transmits a signal requesting termination of retransmission of the data packet to the AN if no errors are found in the data packet after decoding.
