� Extensions to MU-MIMO from Rel-8 fulfills the requirements in some scenarios<br />
(Urban Macro/Micro <strong>DL</strong>)<br />
� More advanced configurations provide even further performance beyond the<br />
requirements<br />
� The 3GPP self-evaluation was widely supported with the participation of 18 company entities in<br />
the simulations which have contributed to a high level of confidence in the reliability of the<br />
conclusions reached. The following 18 corporate entities (listed below in alphabetical order)<br />
participated in these simulations:<br />
o Alcatel-Lucent/Alcatel-Lucent Shanghai Bell, CATT, CMCC, Ericsson/ST-Ericsson,<br />
Fujitsu, Hitachi, Huawei, LGE, Motorola, NEC, Nokia/Nokia Siemens Networks, NTT<br />
DoCoMo, Panasonic, Qualcomm, RITT, Samsung, Texas Instruments, ZTE<br />
A summary of the LTE-Advanced submission technical capabilities can be found in Appendix F, which is<br />
taken from the 3GPP presentation made at the ITU-R Third Workshop on IMT-Advanced and focused on<br />
Candidate Technologies and Evaluation. 158 Particularly, the results of the 3GPP self-evaluation of the<br />
technology are directly provided in the Appendix E.<br />
D.2 TARGET REQUIREMENTS FOR 3GPP LTE‐ADVANCED TO MEET/EXCEED ITU‐R IMT‐<br />
ADVANCED REQUIREMENTS<br />
D.2.1 ESTABLISHING THE 3GPP WORK ON SATISFYING IMT‐ADVANCED – THE CREATION<br />
OF LTE‐ADVANCED<br />
3GPP has responded to the global developments of IMT-Advanced by taking on board the ITU-R<br />
requirements and timeframes for IMT-Advanced and has agreed on a Study Item 159 for its candidate<br />
technology development. 3GPP has given the nomenclature of LTE-Advanced to its candidate technology<br />
in order to reflect the basis of LTE as its starting point for any needed enhancements required to exceed<br />
the ITU-R performance benchmarks and to be a forward pointer into the “Advanced” realm.<br />
In particular the LTE-Advanced Study Item states, in part, the following (section numbers of the original<br />
document retained):<br />
