Interference mitigation in D2D communication underlaying LTE-A network

This chapter focuses on underlay in-band device-to-device (D2D) communication. The applicability of D2D spans across many areas including, but not limited to proximity-based services, e.g. social application, smart communication between vehicles, content distribution, multicasting, peer-to-peer communication, location aware advertisement, and public safety. There are two types of D2D communication, namely, in-band and out-band. The major difference between the two is the frequency spectrum band in which the D2D communication is operating. D2D communications can provide higher spectral efficiency and network throughput, which are the two main requirements for the long term evolution-advanced (LTE-A) network. D2D communication underlaying cellular network is expected to operate within the same coverage area of an existing cell of LTE-A network and share the same cellular spectrum. Various interference mitigation schemes such as power control, efficient resource allocation, and multi-antenna beam forming among others have been reviewed and critically analyzed.
