Abstract

We propose dynamic spectrum leasing (DSL) as a new paradigm for dynamic spectrum sharing (DSS) in (cognitive) radio networks to improve spectrum utilization. In contrast to exiting hierarchical dynamic spectrum access (DSA), spectrum owners in proposed DSL networks are expected to dynamically adjust the amount of secondary interference they are willing to tolerate in response to the demand from secondary transmitters [1]. The secondary transmitters in turn attempt to achieve maximum possible throughput opportunistically while not violating the interference limit set by the primary system. In this paper, we first develop a formal signal model for DSL coexistence of primary and secondary systems, and then model their interactions as a non-cooperative DSL-game. We propose a class of utility functions for the two types of users based on demand and value, establish and analyze the equilibrium performance of a proposed DSL-based network and show how a practical implementation can be justified with minimal interaction between the two systems.
