Spatial channel model for Multiple Input Multiple Output (MIMO) simulations
The present document details the output of the combined 3GPP-3GPP2 spatial channel model (SCM) ad-hoc group (AHG).
The scope of the 3GPP-3GPP2 SCM AHG is to develop and specify parameters and methods associated with the spatial channel modelling that are common to the needs of the 3GPP and 3GPP2 organizations. The scope includes development of specifications for:
System level evaluation.
Within this category, a list of four focus areas are identified, however the emphasis of the SCM AHG work is on items a and b.
a) Physical parameters (e.g. power delay profiles, angle spreads, dependencies between parameters)
b) System evaluation methodology.
c) Antenna arrangements, reference cases and definition of minimum requirements.
d) Some framework (air interface) dependent parameters.
Link level evaluation.
The link level models are defined only for calibration purposes. It is a common view within the group that the link level simulation assumptions will not be used for evaluation and comparison of proposals.
