Annex Test environments and channel models Test environments and channel models This section provides the reference channel for each test environment. These test environments are intended to cover the range of IMT-Advanced operating environments. The test operating environments are considered as a factor in the evaluation process of the candidate RITs. The reference models are used to estimate the critical aspects, such as the spectrum, coverage and power efficiencies. 1.1 Test environments, deployment scenarios and network layout Evaluation of candidate IMT-Advanced RIT/SRITs will be performed in selected scenarios of the following test environments: an urban macro-cellular environment targeting continuous coverage Base coverage – for pedestrian up to fast vehicular users. an urban micro-cellular environment with higher user density focusing on Micro-cellular: – pedestrian and slow vehicular users. an indoor environment targeting isolated cells at offices and/or in hotspot based on Indoor: – stationary and pedestrian users. a macro-cellular environment with high speed vehicles and trains. High – The deployment scenarios that shall be used for each test environment are shown in Table 8-1; information of the respective channel models is given in Table A1-1. A1-1 Selected deployment scenarios for evaluation and the channel models Test environment Base coverage Microcellular Indoor High speed Deployment Urban macro-cell micro-cell Indoor hotspot Rural macro-cell scenario scenario scenario scenario scenario Channel model UMa UMi InH RMa Urban macro Urban micro Indoor hotspot macro (LoS, NLoS) (LoS, NLoS, (LoS, NLoS) (LoS, NLoS) Suburban macro-cell scenario (and corresponding SMa channel model) is an optional scenario for the base coverage urban test environment. Initial focus for deployment and most challenges in IMT-Advanced system design and performance will be encountered in populated areas. However, in the evaluation the provisions for ubiquitous coverage and the associated performance also in rural areas need to be addressed. 1.2 Test environments For evaluation of candidate IMT-Advanced RIT/SRITs in the four selected test environments, a set of reliable and measurement-based channel models are needed. Channel models have to be accurate due to the fact that radio propagation has a significant impact on the performance of future
