PROJECT TITLE :

Group communication over LTE: a radio access perspective

ABSTRACT:

Long Term Evolution, which has its roots in commercial mobile communications, has recently become an influential solution to future public safety communications. To verify the feasibility of LTE for public safety, it is essential to analyze whether an LTE system optimized for one-to-one communications is capable of providing group communication, which is one in every of the foremost important service concepts in public safety. In general, a variety of initial responders for public safety need to make a cluster for communicating with each alternative or sharing common information for collaboration on their mission. In this article, we tend to analyze how the current LTE system can support cluster communication from the aspect of radio access. Based mostly on the necessities for cluster communication, we tend to validate whether every LTE-enabled radio access method will efficiently support cluster communication. In addition, we have a tendency to propose a brand new multicast transmission scheme, called index-coded HARQ. By applying the index coding concept to HARQ operations, we have a tendency to show that the LTE system will provide cluster communication that's more refined in terms of radio resource efficiency and scalability. We tend to finally evaluate the performance of LTE-enabled group communication using several radio access methods and show how the proposed transmission scheme enhances performance via system-level simulations.
