Abbreviated name
ConstVal
Description
This parameter is the correction value when calculating the initial transmission power of PRACH preamble.

Abbreviated name
PRStep
Description
This parameter indicates the power ramp step used by the UE when it does not receive any responses from AICH after sending a preamble. This parameter is used to be added to the previous power, and then the next preamble is sent at this new power.
