Chapter 11: Channel simulator 37
As a result, with this scenario, UE will move from its initial position (5.71,3.27) following the
direction(42.43) at the speed of 5 km/h. Once UE has reached the max distance (20 meters), it
will bounce with a random angle back inside the cell.
11.4 Channel simulation scenario through remote API
To get deeper control of UE position, speed and direction it’s possible to use the remote API to
control the UE position. First of all, ue.cfg file must be filled correctly
11.4.1 Cell configuration parameters to be provided:
See [cell configuration parameters], page 34,
11.4.2 UE configuration parameters to be provided:
• Position
• initial radius
• speed
• direction
• noise spd
• channel
see lteue.pdf for more details about these parameters.
