The reason is that when the QoS constraint is in the range of IMT-Advanced
requirement, P2 is the major part of the total power consumption (the downlink SE of the IMT-Advanced
requirement is up to 3 bits/s/Hz and 2.25 bits/s/Hz for indoor usage.
Lakhani: IMT-2020 is an ITU term for the next step after IMT-2000 and IMT-Advanced
which covered 3G and 4G respectively.
LTE-A was ratified by the International Telecommunication Union (ITU) as an IMT-Advanced
4G technology in November 2010, and has adopted relaying for cost-effective throughput enhancement and coverage extension .
This was followed by IMT-Advanced
and now IMT-2020.
However, LTE network does not meet some specific International Mobile Telecommunications-Advanced (IMT-Advanced
) demands, which doesn't make it part of fourth generation networks.
Mobile subscribers will enjoy the benefits of increased mobile broadband Internet speeds in 2016 when the operators begin to provide services based on IMT-Advanced
(1) And to facilitate worldwide compatibility, LTE-A meets the requirements of the International Telecommunications Union's IMT-Advanced
(where IMT stands for International Mobile Telecommunications) standard.
The 1st release of the 3GPP long term evolution (LTE) standard does not totally complete the ITU 4G demands known IMT-advanced
. First released LTE is not backwards well-matched with 3G, but is a pre-4G or 3.9G technology, however sometimes branded 4G through the service suppliers.
The focus here is the latest version of the network protocol, LTE release 11, also called LTE-Advanced, which is the major technology approved by the ITU as fulfilling the IMT-Advanced
In 2008, International Telecommunication Union-Radio Sector (ITU-R) defines new specifications for 4G standard called International Mobile Telecommunication Advanced (IMT-Advanced
The International Telecommunication Union Radio Section (ITU-R) has commenced the process of developing ITU-R Recommendations for the terrestrial components of the International Mobile Telecommunications-Advanced (IMT-Advanced
) radio interface to enable high-quality mobile services.
Third, LTE-Advanced shall meet or exceed the IMT-Advanced
requirements within the ITU-R time plan.
