In this Morden age from small to large applications are directly or indirectly depends on communication and it’s infrastructure. This paper is dedicated to study about the wireless communication and the new technologies which helps to advance the communication performance. Therefore first the wireless communication is reported and then the MIMO communication technique is investigated. Meanwhile it is observed the communication is taken place in two different flavour namely uplink and downlink. Thus both the techniques are explored and then decided to work for uplink communication. Therefore the paper also includes the study about Uplink communication is based on OFDMA and SC-FDMA. Finally the frequently used technique namely MU-MIMO has also been discussed in this paper. In addition of that for further work the key conclusion of the conducted study is also provided in the paper.

Keywords: LTE communication, uplink and downlink, OFDMA, SC-FDMA, MU-MIMO
