Abstract

Spectrum sharing is emerging as a key strategy for future wireless communications systems. Enforcement is a requirement for spectrum sharing to protect the incumbent of the spectrum from bad interference. Practical schemes have linked together ex-ante and ex-post enforcement. The design of the overall enforcement system may give more emphasis to one or the other. The emphasis in commercial-government sharing in the United States has been on ex-ante measures [4,5]. Determining the role of ex-post enforcement in a spectrum sharing scheme is of significant importance since spectrum sharing will inevitably result in interference events. To evaluate the role of the ex-post enforcement approach, we will consider numerical examples where we compare the cost of the ex-post only enforcement to the cost of the ex-ante only enforcement on one of the suggested bands for spectrum sharing (1695-1710 MHz). The cost of the ex-post enforcement in our model depends on the penalty value that Primary User (PU) uses to control interference events and the probability of detecting the interference. The penalty value depends on two factors which are changeable and unchangeable enforcement costs. The cost of the ex-post only enforcement has two variables that affect it, which are probability of detection; and the changeable enforcement cost. The numerical results show how these two variables affect one another, and their effect on the radius of the
