Data traffic is increasing day by day so does the demand of higher speed which makes fifth generation inevitable. In previous generations there were some challenges that couldn’t be handled even by 4G, such as the spectrum crisis and high energy consumption. 5G is the technology which will be the solution to the requirements of today. For 5G, very high frequencies with massive bandwidths and extraordinary base stations are required. 5G will operate above 6 GHz. In this paper we are trying to describe some disruptive technologies that will be helpful in the achievement of high data rates in 5G. We will try to describe these technologies by using previous literature.
