An Effective Review on Relaying In LTE-Advanced and WiMAX Networks

Abstract: LTE is a latest cellular system, it is standardized by 3rd Generation partnership project (3GPP), and it is employed to satisfy increasing customer demand for high speed services also to fulfil demand for user experience with full mobility. With the ever growing demand of data applications, traditional cellular networks face the challenges of providing enhanced system capacity, extended cell coverage, and improved minimum throughput in a cost-effective manner. Wireless relay stations, especially when operating in a half duplex operation; make it possible without incurring high site acquisition. Design of wireless relay stations faces the many challenges of providing backward compatibility, minimizing complexity, and maximizing efficiency. In this review paper we provide an overview of relaying mechanism in LTE-Advanced and WiMAX and than explain relaying handover mechanism over LTE-Advanced and WiMAX.
