New Radio in the Pretext of Cell-free Massive MIMO

EasyChair Preprint 5699

Abstract

The fifth generation (5G) of mobile communication, technically known as New Radio(NR) is a reality now. This 5G networks are being in- stalled all around the world and the first line of 5G devices are already commer- cially available. 5G networks provide seamless connectivity and excellent qual- ity of service to cope up with the ever increasing demand of digital real-time data. Massive MIMO(multiple-input-multiple-output) is a key constituent for 5G networks. The principle of the technology is to transmit/receive signals to/ from multiple users coherently. The major drawback of such a massive MIMO system is inter-cell interference which affect signals for the users at edges of the cell. To overcome this a revolutionary approach is given in this paper to make every user as the cell-center by increasing the number of array of antennas at base stations(BSs) referred as access points(APs) such that no user experiences a cell edge is called as Cell-free massive MIMO. As a result not even a single user is affected by inter-cell interference.

Keyphrases: 5G, Access Points, Base stations, Cell-free massive MIMO, Massive MIMO, New Radio, cell edge, inter-cell interference
