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.
