Figure B.4-1 illustrates the moving propagation conditions for the test of the UL timing adjustment performance. The time difference between the reference timing and the first tap is according Equation (B.4-1). The timing difference between moving UE and stationary UE is equal to Δτ – (TA 31)16Ts. The relative timing among all taps is fixed. The parameters for the moving propagation conditions are shown in Table B.4-1.

NOTE 1: Multipath fading propagation conditions for Scenario 1 were derived for Band 1 with additional rounding applied to the Doppler frequency calculated for the specified UE speed.

NOTE 2: In Scenario 2, the UE speed is only used to calculate and the Doppler shift is not applied to the channel.
