18、 Naming for International Mobile Telecommunications Resolution ITU-R 57-1 Principles for the process of development of IMT-Advanced The ITU Radiocommunication Assembly, considering a) that IMT systems are mobile broadband systems including both IMT-2000 and IMT-Advanced; b) that IMT-Advanced systems
19、 include the new capabilities of IMT that go beyond those of IMT-20001; 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 supp
20、ort 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 im
21、provement 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
22、 and with fixed networks; 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; 1 Recommendations ITU-R M.1457 and ITU-R M.2012 are two sep
23、arate, 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 two documents. Rec. ITU-R M.2012-2 3 enhanced peak data rates to support advanced se
24、rvices and applications (100 Mbit/s for high and 1 Gbit/s for low mobility were established as targets for research)2; g) that these features enable IMT-Advanced to address evolving user needs; h) that the capabilities of IMT-Advanced systems are being continuously enhanced in line with technology d
25、evelopments; 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
26、for 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, recognizi
27、ng a) that Resolution ITU-R 57-1 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, no
28、ting a) 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.2
29、012-0 (01-2012); b) that IMT-ADV/27 provides a summary of the information as requested in IMT-ADV/25 (Rev.1) Section 3 (“Revision process in the case of existing IMT-Advanced technologies for Updates requiring a modification of the GCS or the DIS”) for revision 1 of Recommendation ITU-R M.2012 (2014
30、) and contains the conclusion on the acceptability of the proposed update, recommends 1 that the terrestrial radio interfaces for IMT-Advanced should be: “LTE-Advanced”3; and “WirelessMAN-Advanced”4; 2 that the information provided or referenced in Annexes 1 and 2 should be used as the complete set
31、of standards for the detailed specifications of the terrestrial radio interfaces of IMT-Advanced. 2 Data rates sourced from Recommendation ITU-R M.1645. 3 Developed by 3GPP as LTE Release 10 and Beyond (Long Term Evolution-Advanced). 4 Developed by IEEE as the WirelessMAN-Advanced specification inco

33、entified in this Recommendation have been developed by the ITU in collaboration with the GCS6 Proponents and the Transposing Organizations. It is noted from Document IMT-ADV/24(Rev.2)7, that: The GCS Proponent must be one of the RIT8/SRIT9 Proponents for the relevant technology, and must have legal
34、authority to grant to ITU-R the relevant legal usage rights to the 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 part
35、icular technology, and must have the relevant legal usage rights. It is further noted that GCS Proponents and Transposing Organizations must also qualify appropriately under the auspices of Resolution ITU-R 9-4 and the ITU-R “Guidelines for the contribution of material of other organizations to the
36、work of the Study Groups and for inviting other organizations to take part in the study of specific matters (Resolution ITU-R 9-4)”. 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 st
37、andardization has been undertaken within the recognized Transposing 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
38、to enable completion of this Recommendation within the aggressive 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-s
39、cales to be maintained. The main body of this Recommendation has been 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 o
40、n behalf of 3GPP” (the GCS Proponent) and ARIB, ATIS, CCSA, ETSI, 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

Rec. ITU-R M.2012-2 5 bei
42、ng undertaken within the external organization. This information 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. This general agreement, noting that the detailed information
43、of the radio interface should to a large extent be achieved by reference to the work of external organizations, highlights not only the ITUs significant role as a catalyst in stimulating, coordinating and facilitating the development of advanced telecommunications technologies, but also its forward-
44、looking and flexible approach to the development of this and other telecommunications standards for the 21st century. A more detailed understanding of the process for the development of the first release of this Recommendation may be found in Document IMT-ADV/24(Rev.2) whereas details on the process
45、 for the development of revisions of this Recommendation may be found in Document IMT-ADV/25(Rev.1). 1.1 Overview of the radio interface technology 1.1.1 Overview of the SRIT The IMT-Advanced terrestrial radio interface specifications known as LTE-Advanced and based on LTE Release 10 and Beyond are
46、developed by 3GPP. In 3GPP terminology, the term E-UTRA (Evolved-UTRA) is also used to indicate the LTE radio interface. 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 TD
47、D RIT is also known as TD-LTE Release 10 and Beyond or TD-LTE-Advanced. The two RITs 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 T
48、DD RIT individually, and consequently the Set of RITs (SRIT), meet all the ITU IMT-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, me
49、et the requirements of Resolution ITU-R 57-1, 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 enhanced. The radio aspects of LTE-Advanced also include the capabilities of LTE Release 8 and LTE Release 9. Information on the Radio specifications Release 8 and Release 9 is provided in 1.2.2.1.
