4 Introduction
At the 3GPP TSG RAN #39 meeting, the Study Item description on "Further Advancements for E-UTRA (LTE-
Advanced)" was approved (RP-080137).
The justification of the Study Item was as follows;
IMT-Advanced is entering the phase of the process in ITU-R addressing the development of the terrestrial radio
interface recommendations. To announce this stage of the process for IMT-Advanced, ITU-R has issued a Circular
Letter(CL) to invite submission of candidate Radio Interface Technologies (RITs) or a set of RITs (SRITs) for IMT-
Advanced. The key features of IMT-Advanced delineated in the CL are:
- a high degree of commonality of functionality worldwide while retaining the flexibility to support a wide range
of services and applications in a cost efficient manner;
- compatibility of services within IMT and with fixed networks;

3GPP TR 36.913 version 15.0.0 Release 15 6 ETSI TR 136 913 V15.0.0 (2018-09)
- capability of interworking with other radio access systems;
- high quality mobile services;
- user equipment suitable for worldwide use;
- user-friendly applications, services and equipment;
- worldwide roaming capability; and
- enhanced peak data rates to support advanced services and applications (100 Mbit/s for high and 1 Gbit/s for low
mobility were established as targets for research) .
The base line requirements for IMT-Advanced will be concluded in ITU-R WP 5D #2 (June 2008) and communicated
in an Addendum to the Circular Letter in the July 2008 timeframe.
In the WRC07, the following spectrum bands were proposed as additions to the prior identified bands, and the parts of
the existing and new bands are globally or regionally identified for IMT, which is the new root term to encompass both
IMT-2000 and IMT-Advanced.
- 450 MHz band
- UHF band (698-960 MHz)
- 2.3 GHz band
- C-band(3400-4200 MHz)
In 3GPP, E-UTRA should be further evolved for the future releases in accordance with:
- 3GPP operator requirements for the evolution of E-UTRA
- The need to meet/exceed the IMT-Advanced capabilities.
Considering the above, 3GPP TSG-RAN should study further advancements for E-UTRA (LTE-Advanced) toward
meeting:
- Requirements for IMT-Advanced and provide ITU-R with proposals of RITs or SRITs according to the defined
ITU-R time schedule provided in the Circular Letter and its Addendums.
- 3GPP operators requirements for the evolution of E-UTRA
5 Objective
The objective of Further Advancements for E-UTRA is as follows;
A) Define a framework for further advancements of E-UTRA and E-UTRAN (to be referred to as Advanced E-
UTRA and Advanced EUTRAN considering:
- The time schedule of ITU-R
- That the work on Advanced E-UTRA and Advanced E-UTRAN must not introduce any delay to the
completion of the Release 8 specification of E-UTRA and E-UTRAN
- That the general enhancements of specifications for Release 8 E-UTRA and E-UTRAN are maintained and
progressed in a focused and efficient manner.
B) Define requirements for Advanced E-UTRA and Advanced E-UTRAN based on the ITU-R requirements for
IMT-Advanced as well as 3GPP operators own requirements for advancing Release 8 E-UTRA AND E-UTRAN
considering:
- E-UTRA radio technology and architecture improvements
- Support for all radio modes of operation
- Interworking with legacy RATs (scenarios and performance requirements)

- Backward compatibility of Advanced E-UTRA and Advanced E-UTRAN with Release 8 E-UTRA and E-
UTRAN i.e.
- an Release 8 E-UTRA terminal can work in an Advanced E-UTRAN,
- an Advanced E-UTRA terminal can work in an Release 8 E-UTRAN and
- non-backward compatible elements could be considered based on RAN decision
- Newly identified frequency bands and existing frequency bands, and their advantages and limitations, in
particular, the consideration of the WRC-07 conclusions, to ensure that Advanced E-UTRA can
accommodate radio channel bandwidths commensurate with the availability in parts o
