Parameter Name |
AMR DL Qual. Upper Threshold |
|---|---|
Description |
When the power control step is calculated based on the signal quality, the upper threshold and the lower threshold of the quality zone are set. When the signal quality exceeds the upper threshold or is below the lower threshold, power control is performed. This parameter specifies the upper threshold of the downlink quality for power control. The mapping between the BER and the quality level is as follows: Level 0: BER smaller than 0.2% Level 1: BER ranges from 0.2% to 0.4% Level 2: BER ranges from 0.4% to 0.8% Level 3: BER ranges from 0.8% to 1.6% Level 4: BER ranges from 1.6% to 3.2% Level 5: BER ranges from 3.2% to 6.4% Level 6: BER ranges from 6.4% to 12.8% Level 7: BER greater than 12.8% |

If this parameter is set to a too small value, the quality is good without power control. Thus, the battery life is reduced and the network interference is increased. If this parameter is set to a too great value, the quality is poor without power control, thus the conversation quality is degraded. |

Parameter Relationship |
When power control is performed on the BTS according to the signal quality, compare the quality of the BTS transmit signal with the DL Qual. Upper Threshold. When the signal quality level is smaller than the value of this parameter, adjust the BTS power by one level downward. In the current algorithm, if the receive level of the MS minus the MAX Down Adj. PC Value by Qual. is smaller than the DL RX_LEV Lower Threshold, the transmit power is not adjusted. |
