UL Qual. Upper Threshold

Parameter Name

UL 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 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%

Configuration Policy

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.

Recommended Value

0

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. Upper Threshold. When the signal quality level is smaller than the value of this parameter, adjust the power of the MS by one level downward. In the current algorithm, if the receive level of the BSC minus the MAX Down Adj. PC Value by Qual. is smaller than the UL RX_LEV Lower Threshold, the transmit power is not adjusted.
