How Do I Change UE TX Power Levels?

How Do I Change UE TX Power Levels?

Last updated: January 15, 2009

A. Using Closed Loop Power Control

  1. Press the CALL SETUP key.
  2. Press the More key on the right side two times to go to Call Parms ( 3 of 3) .
  3. Press the UE Target Power ( F7 ) key, and set the desired average transmit power of the UE (see UE Target Power ).
  4. Press the UL CL Power Ctrl Parameters ( F8 ) key.
  5. Highlight the UL CL Power Ctrl Mode and select Active bits . This activates the uplink closed loop power control.
  6. 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.
  7. 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

  1. Press the CALL SETUP key.
  2. Press the More key on the right side two times to go to screen 3 of 3 .
  3. Press the UL CL Power Ctrl Parameters ( F8 ) key.
  4. 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.
  5. 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.
  6. 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.
