Parameter Name |
AMR UL Qual. Lower 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 lower threshold of the uplink 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 great value, the quality is poor without power control. Thus, the conversation quality is degraded. If this parameter is set to a too small value, the quality is good without power control. Thus, the battery life is reduced. |

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