A new joint feedback and scheduling scheme based on the users´ satisfaction

In this paper, a new joint feedback and scheduling scheme based on the users´ satisfaction has been proposed. The scheme divides the users into different groups based on the QOS of users and calculates the users´ satisfaction. Based on the satisfaction, the scheme takes it as scheduling weight of ZFBF-SUS in real-time users. Also, the scheduling weight of non-real-time users has been analyzed. It shows that the PDF of the scheduling weight of non-real-time users is given by gamma distribution. Furthermore, an appropriate feedback threshold has been derived. The scheme tradeoff the users´ satisfaction, system sum-rate and feedback ratio. It reduces the feedback ratio effectively and proves the average of users´ satisfaction with little decreasing of system sum-rate.
