Abstract

There is a rapid advancement in wireless communication technology providing the network services anywhere and
anytime. 4G communication systems are being developed to solve the various problems the current communication
systems (3G, 2.5G) are facing.4G will be an intelligent technology that will reduce the number of different
technologies to a single global standard. Cognitive Radio (CR) is the key enabling technology for next generation
networks. Cognitive Radio techniques provide the capability to use or share the spectrum in an opportunistic
manner. With the use of CR, 4G wireless networks will support global roaming across multiple wireless and mobile
networks. In this paper, the Role of CR in 4G Communications is reviewed. The recent research being done on
Cognitive Radio and 4G technologies is identified. The main possibilities of implementing Cognitive Radios in 4G
Communication Systems are surveyed. IEEE 802.22 networks are cognitive technology based networks which will
enhance the performance of 4G Communication systems. IEEE 802.16h (WiMAX) provide extensions to support
unlicensed coexistence. Keywords: Cognitive Radio (CR), WiMAX, 4th Generation (4G)
