5.7 System Downlink/Uplink Config 5.7.1 Downlink Output Power Config (Power
Sharing Process)
Step 1. Set Carrier Info in Chapter 5.3.1.3, including the operator info,
carrier info. The DL ATTN can be set to default value in power sharing config.
Step 2. Set the power sharing parameters in chapter 5.3.1.4 – Assign each
operator’s power share (percentage). – Select the carrier’s power assignment
mode for each operator (Density /Even). Density mode: power assignment based
on carrier bandwidth. Even mode: power assignment based on the number of
carriers. – Config MIMO 1 and MIMO 2 channel. – Select the calculate button to
active the value, then the DL ATT value in Step 1 will be automatically
calculated. – Select the `Power Share Lock’ button to lock the ATT config. –
The system will automatically emit the output target power based on power
sharing configuration if the DCU input power is within the operation range.
Step 3. Set RIU ATTN to meet DCU input power range according to chapter 5.1.2
– Set RIU high gain mode (ON/OFF) and DL ATTN to suitable value to meet DCU
input operation range.
