WINNER II D1.1.2 V1.2 Above it has been assumed that the CIR samples are taken for each MIMO channel separately and that the angle information has been vanished in this process. This is the case, when using the model e.g. with the WIM implementation [WIN2WIM]. 5.4.2.2 Down-scaling in frequency domain If desired, the down-scaling can also be performed in the frequency domain. Then the starting point will be the original CIR specified in the delay domain. This CIR is transformed in the frequency domain for each simulation block. Then the transformed CIR can be filtered as desired, e.g. by removing the extra frequency samples, and used in the simulation as normally. The maximum frequency sampling interval is determined by the coherence bandwidth 1 B c = , (5.4) Cσ τ where σ τ is the rms delay spread and C is a scaling constant related to fading distribution. 5.4.3 FDD modeling In next steps we explain how to obtain both uplink and downlink channel of an FDD system with bandwidths of 100 MHz. The center carrier frequencies are f c and f c + ∆f c : • Define BS and MS positions, calculate the channel for one link, e.g. BS to MS at certain carrier frequency • Save the small scale parameters • Exchange the positions of the BS and MS f c • Calculate the other link, in this example the MS to BS by: o Using saved small scale parameters o Randomizing the and initial phases of rays o Changing the carrier frequency to + ∆f 5.5 Comparison tables of WINNER channel model versions This section shows the main differences between the different versions of WINNER channel models (Phase I (D5.4), Phase II Interim (D1.1.1), and Phase II Final (D1.1.2) models). Note! This section is aimed as comparison of the different versions, not as the primary source of channel model parameters. f c Table below shows which scenarios are available in the different versions. Note that all the scenarios of Phase I have been updated in Phase II models.
