How Do I Change UE TX Power Levels?
Last updated: January 15, 2009
A. Using Closed Loop Power Control
-
Press the
CALL SETUP
key.
-
Press the
More
key on the right side two times to go to Call Parms (
3 of 3)
.
-
Press the
UE Target Power
(
F7
) key, and set the desired average transmit power of the UE (see
UE Target Power
).
-
Press the
UL CL Power Ctrl Parameters
(
F8
) key.
-
Highlight the
UL CL Power Ctrl Mode
and select
Active bits
. This activates the uplink closed loop power control.
-
Highlight the
UL CL Power Ctrl Algorithm
and select power control algorithm as desired. If algorithm
One
is selected for power control, you can also specify the
UL CL Power Ctrl Stepsize
to either 1 dB or 2 dB.
-
Now, the UE's transmit power will be controlled automatically by the closed loop power control to maintain the UE's average power at the value entered for the
UE Target Power
.
B. Controlling the UE's TX Power Manually
-
Press the
CALL SETUP
key.
-
Press the
More
key on the right side two times to go to screen
3 of 3
.
-
Press the
UL CL Power Ctrl Parameters
(
F8
) key.
-
Highlight the
UL CL Power Ctrl Mode
and select a power control mode
other than
Active bits
. This allows you to control the UE's transmit power manually.
-
Highlight the
UL CL Power Ctrl Algorithm
and select power control algorithm as desired. If algorithm
One
is selected for power control, you can also specify the
UL CL Power Ctrl Step Size
to either 1 dB or 2 dB.
-
If you've chosen
Alternating bits
as the power control mode, you can use the
Send Step Up TPC Bit Pattern
(
F10
) key or the
Send Step Down TPC Bit Pattern
(
F11
) key to change the UE's transmit power either up or down by one step.
