A channel sharing scheme to improve system capacity in wireless cellular networks

Enhancing system capacity is an important issue in wireless cellular networks. In this paper, we present a new channel sharing scheme to address this problem. Our basic idea is to allow channels to be shared between adjacent cells. We propose a fixed channel assignment scheme to maximize channel reuse efficiency while allowing channel sharing. An important feature of our sharing scheme is that channel management is localized between adjacent cells, and no global coordination or optimization is required thus simplifying implementation. We provide simulation results comparing our scheme with the fixed channel assignment scheme
