Abstract

The ARQ acknowledge algorithm in LTE system always constructs status information without considering the state distribution of data in receiving window, so this paper puts forward a kind of adaptive acknowledge algorithm, which uses confirming rate to improve performance of system in different basic parameter. With the analyses of the performance, it proved that the adaptive acknowledge algorithm enhances the efficiency of system and the using ratio of wireless resource. As a result, the system gain higher throughput through decreasing retransmission times.
