摘要:
A system and method for inter-cell power control for interference management in an OFDM system is provided. The system provides for a combination use of open loop and closed loop PSD control algorithms. The open loop control is a function of path loss from the serving cell as well as the neighboring cells. The closed loop control updates the end node transmit PSD by listening to the load indicators from the serving cell and at least one other neighboring non-serving cell which generates the highest level of interference. The system thus provides a fast and tight control with multi-cell information that allows improved inter-cell interference control.
