20、nciples for the process of development of IMT-Advanced Handbook on Global Trends in International Mobile Telecommunication. The ITU Radiocommunication Assembly, considering a) that IMT systems are mobile broadband systems including IMT-2000, IMT-Advanced and IMT-2020; b) that IMT-Advanced systems in
21、clude the new capabilities of IMT that go beyond those of IMT-20002; c) that such systems provide access to a wide range of telecommunication services including advanced mobile services, supported by mobile and fixed networks, which are increasingly packet-based; d) that IMT-Advanced systems support
22、 low to high mobility applications and a wide range of data rates in accordance with user and service demands in multiple user environments; e) that IMT-Advanced also has capabilities for high-quality multimedia applications within a wide range of services and platforms providing a significant impro
23、vement in performance and quality of service; f) that the key features of IMT-Advanced 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 an
24、d with fixed networks; 2 Recommendations ITU-R M.1457 and ITU-R M.2012 are two separate, independent, and self-contained Recommendations, each one with a specific scope. Both Recommendations will evolve independently, and there could be some overlap reflected by commonality in content between the tw

27、lopments; i) the necessity of priority services (e.g. emergency calls shall be supported as higher priority than other commercial services); j) that due to the large effective bandwidths required to support the very high data rates needed for the various services offered, allowances must be made for
28、 either much larger single carrier bandwidths (even as spectral efficiencies increase) or aggregation of RF carriers; k) that the rapid development of information technology, including the Internet, has resulted in the aggregation and convergence of various networks and digital devices, recognizing
29、a) that Resolution ITU-R 57-2 on the “Principles for the process of development of IMT-Advanced” outlines the essential criteria and principles used in the process of developing the Recommendations and Reports for IMT-Advanced, including Recommendation(s) for the radio interface specification, notin
30、g that Report ITU-R M.2198 contains the outcome and conclusions of Steps 4 through 7 of the IMT-Advanced process, including the evaluation and consensus building, and provides the characteristics of the IMT-Advanced terrestrial radio interfaces for the first release of Recommendation ITU-R M.2012-0
31、(01-2012), recommends 1 that the terrestrial radio interfaces for IMT-Advanced should be: “LTE-Advanced”4; and “WirelessMAN-Advanced”5; 2 that the information provided or referenced in Annexes 1 and 2 should be used as the complete set of standards for the detailed specifications of the terrestrial
32、radio interfaces of IMT-Advanced. 3 Data rates sourced from Recommendation ITU-R M.1645. 4 Developed by 3GPP as LTE Release 10 and Beyond (Long Term Evolution-Advanced). 5 Developed by IEEE as the WirelessMAN-Advanced specification incorporated in IEEE Std 802.16 beginning with approval of IEEE Std
33、802.16m. 4 Rec. ITU-R M.2012-3 Annex 1 Specification of the LTE-Advanced radio interface technology Background IMT-Advanced is a system with global development activity and the IMT-Advanced terrestrial radio interface specifications identified in this Recommendation have been developed by the ITU in
34、 collaboration with the GCS6 Proponents and the Transposing Organizations. It is noted from Document IMT-ADV/24(Rev.3), that: The GCS Proponent must be one of the RIT7/SRIT8 Proponents for the relevant technology, and must have legal authority to grant to ITU-R the relevant legal usage rights to the
35、 relevant specifications provided within a GCS corresponding to a technology in Recommendation ITU-R M.2012. A Transposing Organization must have been authorized by the relevant GCS Proponent to produce transposed standards for a particular technology, and must have the relevant legal usage rights.
36、It is further noted that GCS Proponents and Transposing Organizations must also qualify appropriately under the auspices of Resolution ITU-R 9-5 and the ITU-R “Guidelines for the contribution of material of other organizations to the work of the Study Groups and for inviting other organizations to t
37、ake part in the study of specific matters (Resolution ITU-R 9-5)”. The ITU has provided the global and overall framework and requirements, and has developed the Global Core Specification jointly with the GCS Proponent. The detailed standardization has been undertaken within the recognized Transposin
38、g Organizations which operate in concert with the GCS Proponent. This Recommendation therefore makes extensive use of references to externally developed specifications. This approach was considered to be the most appropriate solution to enable completion of this Recommendation within the aggressive
39、schedules set by the ITU and by the needs of administrations, operators and manufacturers. This Recommendation has therefore been constructed to take full advantage of this method of work and to allow the global standardization time-scales to be maintained. The main body of this Recommendation has b
40、een developed by the ITU, with each Annex containing references pointing to the location of the more detailed information. This Annex 1 contains the detailed information developed by the ITU and “ARIB, ATIS, CCSA, ETSI, TTA, and TTC on behalf of 3GPP” (the GCS Proponent) and ARIB, ATIS, CCSA, ETSI,
41、TTA, and TTC (the Transposing Organizations). Such use of referencing enables timely completion and update of the high-level elements of this Recommendation, with change control procedures, transposition, and public enquiry procedures being undertaken within the external organization. This informati
42、on has generally been adopted unchanged, recognizing the need to minimize duplication of work, and the need to facilitate and support an ongoing maintenance and update process. 6 A “GCS” (Global Core Specification) is the set of specifications that defines a single RIT, an SRIT, or a RIT within an S
43、RIT 7 Radio Interface Technology. 8 Set of Radio Interface Technologies. Rec. ITU-R M.2012-3 5 This general agreement, noting that the detailed information of the radio interface should to a large extent be achieved by reference to the work of external organizations, highlights not only the ITUs sig
44、nificant role as a catalyst in stimulating, coordinating and facilitating the development of advanced telecommunications technologies, but also its forward-looking and flexible approach to the development of this and other telecommunications standards for the 21st century. A more detailed understand
45、ing of the process for the development of the first release of this Recommendation may be found in Document IMT-ADV/24(Rev.3) whereas details on the process for the development of revisions of this Recommendation may be found in Document IMT-ADV/25(Rev.2). 1 Overview of the radio interface technolog
46、y 1.1 Overview of the SRIT The IMT-Advanced terrestrial radio interface specifications known as LTE-Advanced is based on LTE Release 10 and Beyond are developed by 3GPP. In 3GPP terminology, the term E-UTRA (Evolved-UTRA) is also used to indicate the LTE radio interface, and 3GPP LTE Release 13 and
47、beyond is marked as “LTE-Advanced Pro”. LTE-Advanced is a Set of RITs (Radio Interface Technologies) consisting of one FDD RIT and one TDD RIT designed for operation in paired and unpaired spectrum, respectively. The TDD RIT is also known as TD-LTE Release 10 and Beyond or TD-LTE-Advanced. The two R
48、ITs have been jointly developed, providing a high degree of commonality while, at the same time, allowing for optimization of each RIT with respect to its specific spectrum/duplex arrangement. Both the FDD RIT and the TDD RIT individually, and consequently the Set of RITs (SRIT), meet all the ITU IM
49、T-Advanced minimum requirements in all four test environments defined in all aspects of Services, Spectrum and Technical performance. Furthermore, both the FDD RIT and TDD RIT individually, and consequently the SRIT, meet the requirements of Resolution ITU-R 57-2, resolves 6 e) and f) in all four test environments. The complete set of standards for the terrestrial radio interface of IMT-Advanced identified as LTE-Advanced includes not only the key characteristics of IMT-Advanced but also the additional capabilities of LTE-Advanced both of which are continuing to be
