Towards the development trend of wireless communication networking, regarding the link control difficultiesof in wireless channel with high error probability,real changing and narrow-bandwidt, the efficient and reliable link control method basing complex channel service model is proposed.Firstly,the characteristic of wireless channel service model is analysed. Secondly,the tightly coupled and efficient adaptive control mechanism basing wireless channel service model is proposed,and the adaptive feedback control process in wireless link is designed.Then,the algorithm for grouplength and maximum number of retransmissions are given with the frame structure.Simulation shows that,under the transmission success rate is 85% to 99% with minimum grouplength,the best data group length is 2 to 9 times the minimum grouplength ,and the maximum number of retransmissions is from 9 down to 4. The simulation shows that when the packet is 10 to 100 times the minimum grouplength,compared to no link control status,the transmission success rate is upgraded from 1%～90% to over 99.99%,and the average effective throughput obtain more than twice the improvement.
