Long Term Evolution “LTE” is considered to be one of the most
important and latest communication technologies falling under the fourth
generation of cellular communications technology 4G. LTE supports
high-speed and large bandwidth which makes it
a great candidate to
providing the potential to improve the Quality of Service "QoS"
associated with specific types of data transfer. As a consequence,
researchers have paid their attentions to this type of networks. In fact, it
was a great challenge for researchers to achieve a good level of QoS for
all users as the LTE provides Audio and Data transmission to users at the
same time.
