The system employs an Automatic Transmit Power Control (ATPC) algorithm to dynamically adapt the transmit power of each SU so that it is received by the ODU at an optimal level. The algorithm is managed by the AU/Micro Base Station and optimal values are calculated separately for each SU based on the actual level at which it is received by the ODU. MAP messages transmitted to the SUs include information on the estimated up/down power level change required to achieve optimal transmit power level.
The ATPC parameters are configured in the General Radio Parameters page.
The ATPC Parameters include:
Parameter |
Description |
ATPC Support |
Controls whether the ATPC algorithm should be used to determine current optimal transmit level for each SU served by the Base Station. |
Optimal Uplink RSSI (dBm) |
The Optimal Uplink RSSI sets the target level at which all transmissions should be received by the AU-ODUs for optimal performance. Note that it may differ from the value configured in the General Radio Parameters page, since the actual range supported by AUs in TDD mode is -80 to -74 dBm. |
