Abstract: The Proportional Fair Scheduling (PFS) algorithm is always exploited in multiple input multiple output systems to make a balance between maximising the system throughput and guaranteeing the data rate fairness among different users. Besides the traditional PFS, many modified PFS algorithms have also been proposed to further improve user fairness. Among these, an adaptive PFS algorithm attracts our attention. It defines a new priority number which is multiplying traditional PFS priority number by a factor. And this very factor is the ratio of instantaneous request rate over average request rate. What is different is that while the average transmission rate in traditional PFS has a fixed definition and updating strategy, the average request rate in the adaptive method may not. In this paper, we analyse the adaptive PFS algorithm under different definition and updating strategies on block-diagonal geometric mean decomposition scheme and investigate their performance.
