The era of new wireless communications is upon us.
Eventually it will penetrate into our daily life and change the way
we live just like many technological innovations whose original
research came from the life needs. To achieve these requirements,
the society of 3rd Generation Partnership Project (3GPP) is
presently evolving Long Term Evolution Advanced (LTEAdvanced)
as a development of the standard of LTE. The goal of
this generation is to produce specifications for a new radio-access
technology geared to higher data rates, low latency and greater
spectral efficiency. LTE-Advanced is therefore not a new
technology; it is an evolutionary step in the continuing
development of LTE The description in this article is based on
LTE release 10 and thus provides a complete description of the
LTE-Advanced radio access from the bottom up. Also it provides
a deeper insight into some of the technologies that are part of
LTE and its evolution and introduces describing to the
background for the development of the LTE system, in terms of
events, activities, organizations and other factors that have
played an important role. This paper provides detailed coverage
of the air-interface technologies and protocols that survived the
analysis of the highly sophisticated technology evaluation process
typically used in the LTE-Advanced networks.
