Power Detection Threshold (LTE-Advanced)
-15 dB
-100 to 100 dB
sets the threshold for RB Resource Block power detection mode when RB Auto Detect is enabled and RB AutoDetect Mode is set to Power-based.
Power Detection Theshold is available for both Downlink and Uplink; however, the meaning of threshold is different for each.
For Downlink, if the threshold is -15dB, it means all RBs whose power is higher than the CRS power by -15dB are detected as active.
For Uplink, if the threshold is -15dB, we first detect the peak RB power, then all RBs whose power is higher than the peak RB power by -15dB are detected as active.
