A Review paper on Inband Device to Device Communication

Abstract

The highly increasing demand for mobile users has lead to drastically increase of network usage. This has forced
for the development of new techniques and method of wireless communication. D2D i.e. device to device communication is
one of the new paradigm introduced in order to have successful and stable communication between devices present in the
near vicinity. D2D has gained lot of attention due to its feature of accessing licensed and unlicensed spectrum both. It mainly
is advantageous because of its key feature of offloading the base station loads. It’s a direct communication between
transmitting user end and receiving user end, without hopping from base station. Depending upon the use of spectrum D2D
are of four types in wider sense. And mainly divided as inband and outband. Inband is most adopted techniques for D2D. In
this paper we present a review of different inband device to device communication work from establishing of D2D
communication in inband spectrum, to its method of enhancing use of its resources. Different techniques implemented and
which are the domain which are less exploited and which can further increase use of Inband D2D.
