UL RX_LEV Lower Threshold

Parameter Name

UL RX_LEV Lower Threshold

Description

The power control step is calculated based on the signal level. The signal level has an upper threshold and a lower threshold. Power control is not performed if the signal level is between the upper threshold and the lower threshold. Power control is performed only when the signal level exceeds the upper threshold or is below the lower threshold.

The level values 0 through 63 map to -110 dBm to -47 dBm.

Configuration Policy

If this parameter is set to a too great value, the uplink level becomes high without power control. Thus, the battery life is reduced and the network interference is increased. If this parameter is set to a too small value, the uplink level becomes low, and call drop may easily occur.

Recommended Value

18

Parameter Relationship

This parameter specifies the lower threshold of the uplink signal level for power control. If the signal level is below this threshold, calculate an increased value (= (UL RX_LEV Upper Threshold + UL RX_LEV Lower Threshold)/2 - receive level).

Compare the increased value with MAX Up Adj. PC Value by RX_LEV and MAX Up Adj. PC Value by Qual.. Set the power adjustment step to the minimum value of the three.
