Due to the license-exempt nature of the cognitive radio (CR), multiple CR networks may operate (coexist) on the same channel. In this paper, we first discuss some techniques for self-coexistence of CR local and personal area networks, where the self-coexistence means the coexistence of homogeneous CR networks using the same PHY/MAC protocol. Then, we propose a self-coexistence etiquette for the ECMA TC48-TG1 system, which is a CR personal area network specification in standardization. Simulation results show that the proposed etiquette supports effectively the self-coexistence of ECMA TC48-TG1 networks.
