WINNER II D1.1.2 V1.2
Executive Summary
This deliverable presents WINNER II channel models for link level and system level simulations of local
area, metropolitan area, and wide area wireless communication systems. The models have been evolved
from the WINNER I channel models described in WINNER I deliverable D5.4 and WINNER II interim
channel models described in deliverable D1.1.1. The covered propagation scenarios are indoor office,
large indoor hall, indoor-to-outdoor, urban micro-cell, bad urban micro-cell, outdoor-to-indoor, stationary
feeder, suburban macro-cell, urban macro-cell, rural macro-cell, and rural moving networks.
The generic WINNER II channel model follows a geometry-based stochastic channel modelling
approach, which allows creating of an arbitrary double directional radio channel model. The channel
models are antenna independent, i.e., different antenna configurations and different element patterns can
be inserted. The channel parameters are determined stochastically, based on statistical distributions
extracted from channel measurement. The distributions are defined for, e.g., delay spread, delay values,
angle spread, shadow fading, and cross-polarisation ratio. For each channel snapshot the channel
parameters are calculated from the distributions. Channel realisations are generated by summing
contributions of rays with specific channel parameters like delay, power, angle-of-arrival and angle-ofdeparture.
Different scenarios are modelled by using the same approach, but different parameters. The
parameter tables for each scenario are included in this deliverable.
Clustered delay line (CDL) models with fixed large-scale and small-scale parameters have also been
created for calibration and comparison of different simulations. The parameters of the CDL models are
based on expectation values of the generic models.
Several measurement campaigns provide the background for the parameterisation of the propagation
scenarios for both line-of-sight (LOS) and non-LOS (NLOS) conditions. These measurements were
conducted by seven partners with different devices. The developed models are based on both literature
and extensive measurement campaigns that have been carried out within the WINNER I and WINNER II
projects.
The novel features of the WINNER models are its parameterisation, using of the same modelling
approach for both indoor and outdoor environments, new scenarios like outdoor-to-indoor and indoor-tooutdoor,
elevation in indoor scenarios, smooth time (and space) evolution of large-scale and small-scale
channel parameters (including cross-correlations), and scenario-dependent polarisation modelling. The
models are scalable from a single single-input-single-output (SISO) or multiple-input-multiple-output
(MIMO) link to a multi-link MIMO scenario including polarisation among other radio channel
dimensions.
WINNER II channel models can be used in link level and system level performance evaluation of
wireless systems, as well as comparison of different algorithms, technologies and products. The models
can be applied not only to WINNER II system, but also any other wireless system operating in 2 – 6 GHz
frequency range with up to 100 MHz RF bandwidth. The models supports multi-antenna technologies,
polarisation, multi-user, multi-cell, and multi-hop networks.
This report is divided into two parts. The first part defines the channel model structure and parameters.
The second part (separate volume) contains more detailed information about channel measurements and
analysis.
