The justification of the Study
28、Item was as follows; ETSI ETSI TR 136 913 V14.0.0 (2017-04)63GPP TR 36.913 version 14.0.0 Release 14IMT-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
29、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 su
30、pport a wide range of services and applications in a cost efficient manner; - compatibility of services within IMT and with fixed networks; - capability of interworking with other radio access systems; - high quality mobile services; - user equipment suitable for worldwide use; - user-friendly appli
31、cations, 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 i
32、n 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 I
33、MT, 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 -
34、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 provid
35、ed 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 E
36、UTRAN 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 ETSI ETSI TR 136 913 V14.0.0 (2017-04)73GPP TR 36.913 version 14.0.0 Release 14- That the genera
37、l 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
38、 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-UTR
39、A 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 thei
40、r 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 of the world of wideband channels in the spectrum allocations (above 20 MHz) and at the same t
41、ime being mindful on the need to accommodate those parts of the world where the spectrum allocations will not have availability of wideband channels C) Identify potential solutions, technologies for the Advanced E-UTRA and Advanced E-UTRAN. The study areas include: - Physical layer - Radio interface
42、 layer 2 and RRC - E-UTRAN architecture - RF, including Aspects of wider channel bandwidth than 20 MHz - Advanced system concepts D) To develop documents that will serve as a basis for the documentation to be submitted to ITU-R to provide the 3GPP proposals for IMT-Advanced: 1) An “Early Proposal“ s
43、ubmission that would be sent to ITU-R, to be agreed at RAN #41 (9-12 September 2008), for submission to WP 5D #3 (8-15 October 2008). 2) A “Complete Technology“ submission that would be sent to ITU-R, to be agreed at RAN #44 (26-29 May 2009), for submission to WP 5D #5 (planned for 10-17 June 2009).
44、 3) A “Final“ submission to incorporate updates, additional specific details or feature additions, and the required self-evaluation that would be sent to ITU-R, to be agreed at RAN #45 (22-25 September 2009), for submission to WP 5D #6 (planned for 13-20 Oct 2009). - 3GPP should take note, that by I
45、TU-R convention, the formal submission deadline for ITU-R meetings has been established as 16:00 hours UTC, seven calendar days prior to the start of the meeting. E) Make recommendations for future WIs F) For reference, the Circular Letter as received from the ITU-R (and future Addendums to the same
46、) are annexed to this Work Item and should become an integral part of the WI. ETSI ETSI TR 136 913 V14.0.0 (2017-04)83GPP TR 36.913 version 14.0.0 Release 146 General requirements The following general requirements are valid for Advanced E-UTRA and Advanced E-UTRAN - Advanced E-UTRA and Advanced E-U
47、TRAN shall be an evolution of Release 8 E-UTRA and E-UTRAN - All relevant requirement in 3 are valid also for Advanced E-UTRA and Advanced E-UTRAN - Advanced E-UTRA and Advanced E-UTRAN shall meet or exceed IMT-Advanced requirements within the ITU-R time plan The expectancy is that Advanced E-UTRA s
48、hould provide substantially higher performance compared to what is expected to be the IMT-Advanced requirements in ITU-R. The values provided in clauses 7 and 8 have been expressed as preferred performance of Advanced E-UTRA. These values are recognised as being very ambitious, especially in light o
49、f the ITU-R time plan, and the performance evaluation results generated for LTE R8, but are adopted as long term target for Advanced E-UTRA“ 7 Capability-related requirements 7.1 Peak Data Rate The peak data rate is the maximum data rate to be supported from a system requirement viewpoint (i.e. not from radio performance requirement viewpoint) regardless of radio interface parameters such as the transmission bandwidth and antenna configuration. Advanced E-UTRA should support significantly increased instantaneous peak data rates. At a minimum, Advanced E-UTRA sho
