Introduction
Previously only half duplex had been used for the purpose of operations, this had resulted in
an erosion of the usage of various resources. For the purpose of compensating for the shortcomings
of HD systems that had been resulted due to the usage of half duplex, the usage of full duplex had
been introduced (Zhang, Wang and Long 2015). This usage had promised in improving the spectral
efficiency of this systems of wireless communication, this was done with the help of avoiding using
two number of channels that are completely independent for the purpose of carrying out transmission
that is end to end in nature which is also bi directional as well as inherent in the conventional HD
operations. Numerous researchers had demonstrated the actual feasibility of full duplex
communication in various practical systems (Zhang, Chai and Long 2015). This particular assignment
discusses regarding the advantages as well as disadvantages of using full duplex communication. It
father discusses regarding the issues, challenges, problems and solutions that are encountered in
implementing full-duplex communication in future PCS and 5G systems.
Discussion
On the basis of aforementioned comparisons, the full duplex communication has numerous
advantages but besides this, it had also provided various disadvantages. These are as follows
Advantages of full-duplex communication in 5G systems
Throughput gain: the full duplex mode usually tends to double the obtained throughput of a
particular single hop wireless link in a specific physical layer.
Avoidance of collision: in the carrier sense that is traditional in nature, numerous access along
with the protocol of collision avoidance, every half duplex requires checking of the quality of channel
before it uses it (Chung, Sim and Kim 2015). The full duplex communication only needs the very first
node which helps in initiating the transmission for sensing the channel, this has been required for the
actual purpose of avoiding collision in the process of communication at full duplex nodes which does
not perform the activity of carrier sensing.
Solving the terminal problem that is hidden: the problem regarding the hidden terminals can
be solved with the use of full duplex techniques. Suppose there is a scenario where multiple nodes
are present and has data in the buffer for the purpose of direct transmission to as well as reception
from particular common point for access. Suppose a node transmits information to the access point
and the access point starts the process of transmitting the data to this particular node ( Hong 2014),
the different nodes would be allowed to hear the entire transmission from the actual access point and
hence delay the process of their transmission in order to avoid any sort of collision. In case the access
point does not have any data for sending back to initial node, it would repeat an ACK for the node, this
is done in order to preventing other nodes from transmitting the data.
Issues encountered in implementing full-duplex communication in 5G systems
Performance considered by the dull duplex mode: in a particular process of communication in
the 5G system, a particular full duplex the inputs a signal of the interest which is usually few orders of
this magnitude that is lower in aspect of power compared to the SI signal that has been imposed with
the help of TA output of the device. Interface imposed by this particular TA on the RA would usually
consequently decrease the actual input that is weak in nature and hence degrade the gains of full
duplex (Li and Murch 2014).
Degraded link reliability: the model of full duplex usually suffers from a reliability of link that
has been reduced, regardless of the SNR (Zhang, Long and Wang 2014). A particular state of the art
of a shelf radio is usually able to achieve around 88 percent of the reliability of link as compared to its
half-duplex mode counterpart.
An increased buffer size requirement: in the process of 5G communication, reduction of PLR
of the mode of full duplex is done with the use of a large buffer, this enables the packages to get
forwarded which would have been discarded because of the queue overflow (Hong, Brand and Choi
2014). The effects of the packets loss level is severe in nature in the full duplex mode, a huge size of
buffer us needed as compared to the half-duplex mode.
