The Power Control mechanisms implemented in the E6651A Test Set operates through MAC messages between a BS and SS. Hence it is accessed via the Protocol FN Test menu in BS Emulator mode. All the power control algorithms specified in IEEE802.16 are supported in the E6651A. The E6651A supports closed and open loop mode.
The E6651A provides 4 power control methods, all control the SS Transmitter in 0.25 dB steps:
The Power Control menu has 3 lower level sub-menus. Press Mode, BS Emulator, Protocol FN Test, Power Control to access the power Control Menu. The Setting Menu is used to pre-configure values for each power control algorithm. The required power control algorithm and it's value is selected by repeatedly pressing the Test Mode key to scroll through the list. When selected, the power control message and value can be sent to the SS by pressing Send Message.

Setting |
Default |
Pressing Setting accesses the various power control methods. Values are configured in 0.25 dB steps. To change the value of a function, select it and use the knob to configure the required value or use the numeric keys to enter a value between -128 to 127 (-32 dB to +31.75 dB), pressing Enter to complete the entry. You can configure values for each setting. EIRP and EIRxP_IRmax values are entered directly in 1 dB steps |
|
Test Mode |
RNG-RSP msg. |
Pressing Test Mode scrolls through the list of Power control messages and settings. |
|
Send Message |
|
Pressing Send Message sends the power control message and value displayed in the Test Mode setting to the SS. |
|
RNG-RSP msg. |
0 |
Adjusts the value of the RNG-RSP message. Controls the SS Transmit power in 0.25 dB steps. |
|
Power Control IE |
0 |
Adjusts the value of the Power Control IE message. Controls the SS Transmit power in 0.25 dB steps. |
|
FPC msg. |
0 |
Adjusts the value of the FPC message. Controls the SS Transmit power in 0.25 dB steps. |
|
PMC-RSP msg. |
closed loop, 0 |
Adjusts the value of the PMC-RSP message. Controls the SS Transmit power in 0.25 dB steps. |
|
NI IE |
Off, 42 |
NI IE is UL noise and interference level IE which is used in Open Loop Power Control and broadcast from the BS. |
|
EIRP |
40 dBm |
EIRP is the Base Station's “Equivalent isotropic radiated power” and is basic information to determine the SS Transmit Power. |
|
EIRxP_IRmax |
-10 dBm |
EIRxP_IRmax is the BS maximum received power in Equivalent isotropic and is basic information to determine the SS Transmit power. |
