To contemplate 5G network in the market now, it is evident
that the multiple access techniques in the network are
almost at a still and requires sudden improvement. Current
technologies like OFDMA will work at least for next
50 years. Moreover, there is no need to have a change in
the wireless setup which had come about from 1G to 4G.
Alternatively, there could be only the addition of an application
or amelioration done at the fundamental network to
please user requirements. This will provoke the package
providers to drift for a 5G network as early as 4G is commercially
set up [8]. To meet the demands of the user and
to overcome the challenges that has been put forward in the
5G system, a drastic change in the strategy of designing
the 5G wireless cellular architecture is needed. A general
observation of the researchers has shown in [14] that most of
the wireless users stay inside for approximately 80 percent of
time and outside for approximately 20 percent of the time.
In present wireless cellular architecture, for a mobile user
to communicate whether inside or outside, an outside base
station present in the middle of a cell helps in communication.
So for inside users to communicate with the outside base
station, the signals will have to travel through the walls of
the indoors, and this will result in very high penetration loss,
which correspondingly costs with reduced spectral efciency,
data rate, and energy efciency of wireless communications.
To overcome this challenge, a new idea or designing technique
that has come in to existence for scheming the
5G cellular architecture is to distinct outside and inside
setups [8].With this designing technique, the penetration loss
through the walls of the building will be slightly reduced.
This idea will be supported with the help of massive MIMO
technology [15], in which geographically dispersed array
of antenna's are deployed which have tens or hundreds of
antenna units. Since present MIMO systems are using either
two or four antennas, but the idea of massive MIMO systems
has come up with the idea of utilizing the advantages of large
array antenna elements in terms of huge capacity gains.
To build or construct a large massive MIMO network,
rstly the outside base stations will be tted with large
antenna arrays and among them some are dispersed around
the hexagonal cell and linked to the
