WINNER II pdf - Final Report - Cept

WINNER II D1.1.2 V1.2
and whole the scenario has been updated considerably, as well as the model for indoor hot-spot. Bad
urban scenarios have also been updated. New features of the WINNER II Channel Models include
modelling of the elevation of rays, treating the LOS component of the channel model as a random
variable, and moving scatterers in fixed connections. The differences in the scenarios Indoor-to-Outdoor
and Outdoor-to-Indoor were noticed to be negligible. Therefore these two scenarios have been merged.
Model parameters have been revised in the cases, where new results have pointed this necessary.
Valuable comments have been received also via standardisation work in various standardisation bodies,
especially in IEEE802.16m and ITU-R/8F. We have taken into account several such change proposals.
Probably most important of them is the tuning of our path-loss models.
During the projects WINNER I and WINNER II the models have been evolved, mainly by adding new
scenarios in the models, but also by including new features. In this process we have tried to conserve the
model parameters from changes as much as possible. However, some changes have been inevitable.
Therefore the models are not exactly the same in this and the earlier deliverables. The propagation
scenarios from WINNER Phase I have been included in this document, partly updated. In WINNER
Phase II the following new propagation scenarios have been created and documented in this document:
indoor-to-outdoor, outdoor-to-indoor, bad urban micro-cell, bad urban macro-cell and moving network
scenario. All the propagation scenarios have been listed and introduced in section 2.3. WINNER I,
WINNER II interim, and WINNER II final models are compared in section 5.5.
The deliverable is divided into two major parts. This first part is the main part and defines the channel
model structure and parameters. The second part contains more detailed information about channel
measurements and analysis performed during projects WINNER I and II. The two parts are published in
separate volumes to keep the size of each part reasonable.
SCM, SCME, and WINNER I channel models have been implemented in Matlab, and are available via
WINNER web site. WINNER II channel model implementation is planned to be available by the end of
the year 2007.
Sections 1 - 7 cover the following topics. Section 1 introduces this deliverable. Section 2 expresses some
definitions, like the propagation scenarios and introduces the used measurement tools. Section 3 defines
the channel modelling approach. Section 4 explains the generation of channel coefficients and describes
path loss models as well as parameters for generic models. Section 5 discusses how the channel models
are used in system level (multi-link) simulations, sampling, transition scenarios, bandwidth/frequency
dependence of the models. Parameter tables for reduced variability (CDL) models can be found from
Section 6. Reference list is in Section 7.
