Exponential growth of number of mobile users has led to the increasing demand for bandwidth and channel capacity. Thus 5G has to support new multitude of various mobile applications. The 5G networks not only has capacity constraints but also existing challenges such as network reliability, coverage, energy efficiency and latency with current communication systems. Visible light communication provides broadband wireless data connectivity for high capacity channels. VLC system utilizes intensity modulation, where the information is conveyed through the intensity of LEDs and detected by photodiodes PDs at the receivers. In this survey paper the various techniques for supporting 5G networks using massive MIMO OFDM concept using visible light technology have been discussed.
