LTE-Advanced

In September 2009 the 3GPP Partners made a formal submission to the ITU proposing that LTE Release 10 & beyond (LTE-Advanced) be evaluated as a candidate for IMT-Advanced.

The submission was made jointly in the name of the 3GPP Organizational Partners: ARIB, ATIS, CCSA, ETSI, TTA and TTC, which represent the North American, European and Asian regions and make 3GPP a truly global initiative.

Why “Advanced”?

The ITU has coined the term IMT Advanced to identify mobile systems whose capabilities go beyond those of IMT 2000. In order to meet this new challenge, 3GPPs Organizational Partners have agreed to widen 3GPP’s scope to include the development of systems beyond 3G.

Some of the key features of IMT-Advanced will be;

  • Worldwide functionality & roaming
  • Compatibility of services
  • Interworking with other radio access systems
  • Enhanced peak data rates to support advanced services and applications (100 Mbit/s for high and 1 Gbit/s for low mobility)

In addition to the set of features above, one of the major reasons for aligning LTE with the call for IMT-Advanced is that IMT conformant systems will be candidates for future new spectrum bands to be identified at WRC07.

Release 10 is LTE-Advanced

3GPP continues to study further advancements for the E‐UTRA (Evolved Universal Terrestrial Radio Access) networks.

3GPP Self evaluation of the projects IMT-Advanced proposal is now complete and Member organizations are satisfied that LTE‐Advanced meets all of the requirements (of IMT‐Advanced).

Documentation covering the full 3GPP proposal has been submitted to ITU‐R WP 5D, full details can be downloaded from the 3GPP website:

Technical details

A technical exposition of the LTE-Advanced radio technology was given at a dedicated workshop held in Beijing, 17 - 18 December 2009, hosted by China Mobile and CATR. A general introduction was given by Takehiro Nakamura (Chairman of 3GPP TSG RAN).

This was followed by detailed presentations of various aspects of the radio technology:

Mr Nakamura concluded the presentation of the radio technology with a brief summary of the benefits of the LTE-Advanced system.
