FIELD: radio engineering, communication.
SUBSTANCE: once the power is set, the home base node (HNB) signals to served home user equipment (HUE) its transmit common pilot channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as random access channel (RACH) constant value) to compensate for the error in signalled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, in order to prevent interference, parameters would also be adjusted and signalled to the HUE to reflect the link imbalance.
EFFECT: reducing transmit power in order to prevent co-channel or adjacent channel interference or limit coverage area.
