Abstract

Recently, Cognitive Radio (CR) techniques for effective usage of limited spectrum band have been researched. In this paper, we introduce two criterions, namely primary-user awareness and coordination, and hence classify CR into four categories based on their combinations. For each category, we describe the functionalities which should be supported by the network, and discuss the advantage/disadvantage expected in a sample scenario.
