Abstract

Abstract

In this paper, one sensing-slots scheduling scheme is proposed by using cross-layer design based on IEEE802.22 draft standard. In order to improve the whole system performance, the parameters of TSS scheme in current IEEE802.22 draft are further studied and modified by using cross-layer design. A new sensing-slots scheduling scheme on the MAC layer is proposed from two aspects. First, on the basis of the second-order statistic properties of wireless fading channels on the physical layer, the scheduling frequency of fast sensing timeslot is defined. Then, in order to maximize the transmission throughput for sencondary users, the duration of fine sensing stage is optimized. It is proven that the scheme proposed in this paper makes the TSS scheme more explicit, effective and be able to adapt to varying transmission environments.
