Power optimization using massive MIMO and small cells approach in different deployment scenarios

Power optimization is an important area of concern for the wireless communication in 5G. With the increase in the number of users or subscribers, more amount of power is required for transmission, reception and processing. Hence certain methods or specific technologies should be used to minimize or optimize this power. The main contribution of the paper comprises of the use of massive multiple input multiple output and small cell access point (SCA) approach for the power optimization and the effect of frequency division duplexing and time division duplexing techniques on power optimization. This paper also predicts the optimal number of antennas at the SCA points which are helpful for increasing the degrees of freedom which helps in power optimization. Along with these ideas of power optimization, the prime focus is on the realization of these power optimization approaches on the different deployment scenarios like urban macro heterogeneous deployment scenario in the 3GPP LTE Standard and urban, sub-urban, and rural macro deployment scenario in the ITU-R M.2135 standard.
