8、2135-1 1 REPORT ITU-R M.2135-1 Guidelines for evaluation of radio interface technologies for IMT-Advanced (2008-2009) 1 Introduction International Mobile Telecommunications-Advanced (IMT-Advanced) systems are mobile systems that include the new capabilities of IMT that go beyond those of IMT-2000. S
9、uch 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. IMT-Advanced systems support low to high mobility applications and a wide range of data rates in accordance with u
10、ser and service demands in multiple user environments. IMT-Advanced also has capabilities for high-quality multimedia applications within a wide range of services and platforms providing a significant improvement in performance and quality of service. The key features of IMT-Advanced are: a high deg
11、ree 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 and with fixed networks; capability of interworking with other radio access systems; high-quality mobile
12、 services; user equipment suitable for worldwide use; user-friendly applications, services and equipment; worldwide roaming capability; 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)1
13、. These features enable IMT-Advanced to address evolving user needs. The capabilities of IMT-Advanced systems are being continuously enhanced in line with user trends and technology developments. 2 Scope This Report provides guidelines for both the procedure and the criteria (technical, spectrum and
14、 service) to be used in evaluating the proposed IMT-Advanced radio interface technologies (RITs) or Sets of RITs (SRITs) for a number of test environments and deployment scenarios for evaluation. These test environments are chosen to simulate closely the more stringent radio operating environments.
15、The evaluation procedure is designed in such a way that the overall performance of the candidate RIT/SRITs may be fairly and equally assessed on a technical basis. It ensures that the overall IMT-Advanced objectives are met. 1Data rates sourced from Recommendation ITU-R M.1645. 2 Rep. ITU-R M.2135-1
16、 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 system aspects impacting the radio performance. This Report allows a degree of freedom so as to encomp
17、ass 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. If necessary, additional evaluation methodologies may be developed by each independent evaluation
18、 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 the evaluation results by ITU-R and for posting under additional information relevant to the eva
19、luation group section of the ITU-R IMT-Advanced web page (http:/www.itu.int/ITU-R/go/rsg5-imt-advanced). 3 Structure of the Report Section 4 provides a list of the documents that are related to this Report. Section 5 describes the evaluation guidelines. Section 6 lists the criteria chosen for evalua
20、ting 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 configurations which shall be applied when evaluating IMT-Advanced candidate technology p
21、roposals 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. Annexes 1 and 2 form a part of this Report. 4 Related ITU-R texts Resolution ITU-R 57 Recommen

24、d IMT-2000. Therefore, it is recognized that the technologies for IMT-Advanced can be applied in a variety of deployment scenarios and can support a range of environments, different service capabilities, and technology options. Consideration of every variation to encompass all situations is therefor
25、e not possible; nonetheless the work of the ITU-R has been to determine a representative view of IMT-Advanced consistent with the process defined in Resolution ITU-R 57 Principles for the process of development of IMT-Advanced, and the requirements defined in Report ITU-R M.2134 Requirements related
26、 to technical performance for IMT-Advanced radio interface(s). The parameters presented in this Report are for the purpose of consistent definition, specification, and evaluation of the candidate RITs/SRITs for IMT-Advanced in ITU-R in conjunction with the development of Recommendations and Reports
27、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 not intended to be specific to any particular implementation of an IMT-Advanced technology. They should not b
28、e considered as the values that must be used in any deployment of any IMT-Advanced system nor should they be taken as the default values for any other or subsequent study in ITU or elsewhere. Further consideration has been given in the choice of parameters to balancing the assessment of the technolo
29、gy 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 intended for evaluating system aspects (including those for satellite system aspects). The following principle
30、s are to be followed when evaluating radio interface technologies for IMT-Advanced: Evaluations of proposals can be through simulation, analytical and inspection procedures. The evaluation shall be performed based on the submitted technology proposals, and should follow the evaluation guidelines, us
31、e the evaluation methodology and adopt the evaluation configurations defined in this Report. Evaluations through simulations contain both system level simulations and link level simulations. Evaluation groups may use their own simulation tools for the evaluation. In case of analytical procedure the
32、evaluation is to be based on calculations using the technical information provided by the proponent. In case of evaluation through inspection the evaluation is based on statements in the proposal. The following options are foreseen for the groups doing the evaluations. Self-evaluation must be a comp
33、lete evaluation (to provide a fully complete compliance template) of the technology proposal. An external evaluation group may perform complete or partial evaluation of one or several technology proposals to assess the compliance of the technologies with the minimum requirements of IMT-Advanced. Eva
34、luations covering several technology proposals are encouraged. 4 Rep. ITU-R M.2135-1 6 Characteristics for evaluation The technical characteristics chosen for evaluation are explained in detail in Report ITU-R M.2133 Requirements, evaluation criteria and submission templates for the development of I

Rep. ITU-R M.2135-1 5 Evaluation should be performed in
42、strict compliance with the technical parameters provided by the proponents and the evaluation configurations specified for the deployment scenarios in 8.4 of this Report. Each requirement should be evaluated independently, except for the cell spectral efficiency and cell edge user spectral efficienc
43、y criteria that shall be assessed jointly using the same simulation, and that consequently the candidate RIT/SRITs also shall fulfil the corresponding minimum requirements jointly. Furthermore, the system simulation used in the mobility evaluation should be the same as the system simulation for cell
44、 spectral efficiency and cell edge user spectral efficiency. The evaluation methodology should include the following elements: 1 Candidate RIT/SRITs should be evaluated using reproducible methods including computer simulation, analytical approaches and inspection of the proposal. 2 Technical evaluat
45、ion of the candidate RIT/SRITs should be made against each evaluation criterion for the required test environments. 3 Candidate RIT/SRITs should be evaluated based on technical descriptions that are submitted using a technologies description template. In order to have a good comparability of the eva
46、luation results for each proposal, the following solutions and enablers are to be taken into account: Use of unified methodology, software, and data sets by the evaluation groups wherever possible, e.g. in the area of channel modelling, link-level data, and link-to-system-level interface. Evaluation
47、 of multiple proposals using one simulation tool by each evaluation group is encouraged. Question-oriented working method that adapts the level of detail in modelling of specific functionalities according to the particular requirements of the actual investigation. Evaluation of cell spectral efficie
48、ncy, cell edge user spectral efficiency and VoIP capacity of candidate RIT/SRITs should take into account the Layer 1 and Layer 2 overhead information provided by the proponents, which may vary when evaluating different performance metrics and deployment scenarios. 7.1 System simulation procedures S
49、ystem simulation shall be based on the network layout defined in 8.3 of this Report. The following principles shall be followed in system simulation: Users are dropped independently with uniform distribution over predefined area of the network layout throughout the system. Each mobile corresponds to an active user session that runs for the duration of the drop. Mobiles are randomly assigned LoS and NLoS channel conditions. Cell assignment to a user is based on the propo
