Dear Experts kindly share the optimizaed values for AMR progressive power control for Urban and Rural enviornment. Thanks.
AMR PPC:
AMR Progressive Power Control (PPC) enables you to define four different power level points in which the quality thresholds are changed compared to the ones used in the existing power control algorithm for AMR calls.
The threshold changes are fixed as follows:
28710
You can define these points separately for AMR FR and AMR HR, and in the downlink and uplink direction.
28709
Using AMR FR in the downlink direction as an example, the algorithm for defining the lower threshold with the four relevant AMR PPC parameters and the current pc lower threshold DL Rx qual AMR FR (LDRF) parameter is as follows:
28711
Note that the power control quality threshold values are only changed within the algorithm during an AMR call. The values of the actual parameters, such as LDRF are not changed.
With AMR PPC, the BSC uses the same Px and Nx values and averaging windows as with the normal power control algorithm
