摘要：
This paper first introduces the performance analysis of two classical channel quality indicator (CQI) feedback schemes which are best-n feedback and the threshold based feedback and derives the mathematical expressions of average capacity which is described by Theorem 1 and 2.Then, a reduced feedback scheme is designed for multiple traffics and multi-channel.The novel scheme combines the best-n feedback and the threshold based feedback together to reduce the feedback overhead.The proposed scheme can not only guarantee the quality of service (QoS) requirement of real time (RT) traffic but also reduce feedback overhead at the cost of a marginal increased downlink overhead.Simulation results demonstrated the good performance of the proposed feedback scheme.
