15、GPP-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 specificati
16、ons 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) Antenn
17、a 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
18、not be used for evaluation and comparison of proposals.2 ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the present document.

28、PP TR 25.996 V10.0.0 (2011-03)8Release 104.3 Spatial parameters per pathEach resolvable path is characterized by its own spatial channel parameters (angle spread, angle of arrival, power azimuth spectrum). All paths are assumed independent. These assumptions apply to both the BS and the MS specific
29、spatial parameters. The above assumptions are in effect only for the Link Level channel model.4.4 BS and MS array topologiesThe spatial channel model should allow any type of antenna configuration to be selected, although details of a given configuration must be shared to allow others to reproduce t
30、he model and verify the results. Calibrating simulators at the link level requires a common set of assumptions including a specific set of antenna topologies to define a baseline case. At the MS, the reference element spacing is 0.5, where is the wavelength of the carrier frequency. At the BS, three
31、 values for reference element spacing are defined: 0.5, 4, and 10.4.5 Spatial parameters for the BS4.5.1 BS antenna patternThe 3-sector antenna pattern used for each sector, Reverse Link and Forward Link, is plotted in Figure 4.1 and is specified by 23min1, wher 180mdBAAis defined as the angle betwe
