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 – (T_A −31)×16T_s. The relative timing among all taps is fixed. The parameters for the moving propagation conditions are shown in Table B.4-1.

Table B.4-1: Parameters for UL timing adjustment

Parameter	Scenario 1	Scenario 2
Channel model	Stationary UE: AWGN Moving UE: ETU200	AWGN
UE speed	120 km/h	350 km/h
CP length	Normal	Normal
A	10 s	10 s
	0.04 s-1	0.13 s-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.
