The Design of LTE System: An Energy Efficient Approach

There has been a paradigm shift in the field of mobile communication, with an overwhelming increase in data usage. As more and more users are migrating to Smart-phones, the amount of data being transmitted has increased manifold times. However, such huge amount of data and signal propagation is bound to be detrimental to the ecological balance. Long Term Evolution (LTE), due to its flexibility, and backward compatibility has emerged as the network of choice for 4G and beyond. In this article, the significance of core technologies for LTE network is highlighted, along with the inherent advantage of reducing the energy consumption of cellular network. An Energy Efficient design of LTE is proposed which blends the technologies proposed by 3GPP such as adaptive OFDMA with that of MU-MIMO.
