3、ommunications-Advanced (IMT-Advanced) systems are mobile systems that include the new capabilities of IMT that go beyond those of IMT-2000. Such systems provide access to a wide range of telecommunication services including advanced mobile services, supported by mobile and fixed networks, which are
4、increasingly packet-based.IMT-Advanced systems support low to high mobility applications and a wide range of data rates in accordance with user and service demands in multiple user environments. IMTAdvanced also has capabilities for high-quality multimedia applications within a wide range of service
5、s and platforms providing a significant improvement in performance and quality of service.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;compa
6、tibility 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 applications, services and equipment;worldwide roaming capability;enhanced peak data rates to suppor
7、t advanced services and applications (100 Mbit/s for high and 1 Gbit/s for low mobility were established as targets for research) Data rates sourced from Recommendation ITUR M.1645.These features enable IMT-Advanced to address evolving user needs.The capabilities of IMT-Advanced systems are being co
8、ntinuously enhanced in line with user trends and technology developments.2ScopeThis Report provides guidelines for both the procedure and the criteria (technical, spectrum and service) to be used in evaluating the proposed IMT-Advanced radio interface technologies (RITs) or Sets of RITs (SRITs) for
9、a number of test environments and deployment scenarios for evaluation. These test environments are chosen to simulate closely the more stringent radio operating environments. The evaluation procedure is designed in such a way that the overall performance of the candidate RIT/SRITs may be fairly and
10、equally assessed on a technical basis. It ensures that the overall IMT-Advanced objectives are met.This Report provides, for proponents, developers of candidate RIT/SRITs and evaluation groups, the common methodology and evaluation configurations to evaluate the proposed candidate RIT/SRITs and syst
11、em aspects impacting the radio performance.This Report allows a degree of freedom so as to encompass new technologies. The actual selection of the candidate RIT/SRITs for IMT-Advanced is outside the scope of this Report.The candidate RIT/SRITs will be assessed based on those evaluation guidelines. I
12、f necessary, additional evaluation methodologies may be developed by each independent evaluation group to complement the evaluation guidelines. Any such additional methodology should be shared between evaluation groups and sent to the Radiocommunication Bureau as information in the consideration of
13、the evaluation results by ITU-R and for posting under additional information relevant to the evaluation group section of the ITU-R IMT-Advanced web page (http:/www.itu.int/ITU-R/go/rsg5-imt-advanced).3 Structure of the ReportSection 4 provides a list of the documents that are related to this Report.
14、Section 5 describes the evaluation guidelines.Section 6 lists the criteria chosen for evaluating the RITs.Section 7 outlines the procedures and evaluation methodology for evaluating the criteria.Section 8 defines the tests environments and selected deployment scenarios for evaluation; the evaluation
15、 configurations which shall be applied when evaluating IMT-Advanced candidate technology proposals are also given in this section.Section 9 describes a channel model approach for the evaluation.Section 10 provides a list of references.Section 11 provides a list of acronyms and abbreviations.The foll

18、 service and content providers as noted in Section4.2.2 in Recommendation ITU-R M.1645 “Framework and overall objectives of the future development of IMT2000 and systems beyond IMT2000”. Therefore, it is recognized that the technologies for IMT-Advanced can be applied in a variety of deployment scen
19、arios and can support a range of environments, different service capabilities, and technology options. Consideration of every variation to encompass all situations is therefore not possible; nonetheless the work of the ITU-R has been to determine a representative view of IMT-Advanced consistent with
20、 the process defined in Resolution ITU-R 57, “Principles for the process of development of IMT-Advanced” and the requirements defined in draft new Report ITU-R M.IMT.TECH.The parameters presented in this document are for the purpose of consistent definition, specification, and evaluation of the cand
21、idate RITs/SRITs for IMT-Advanced in ITU-R in conjunction with the development of Recommendations and Reports such as the framework and key characteristics and the detailed specifications of IMT-Advanced. These parameters have been chosen to be representative of a global view of IMT-Advanced but are
22、 not intended to be specific to any particular implementation of an IMT-Advanced technology. They should not be considered as the values that must be used in any deployment of any IMT-Advanced system nor should they taken as the default values for any other or subsequent study in ITU or elsewhere.Fu
23、rther consideration has been given in the choice of parameters to balancing the assessment of the technology with the complexity of the simulations while respecting the workload of an evaluator or technology proponent.This procedure deals only with evaluating radio interface aspects. It is not inten
24、ded for evaluating system aspects (including those for satellite system aspects).The following principles are to be followed when evaluating radio interface technologies for IMTAdvanced: Evaluations of proposals can be through simulation, analytical and inspection procedures. The evaluation shall be
