Title:
METHODS AND APPARATUS FOR POWER CONTROL IN MULTI-CARRIER WIRELESS SYSTEMS
Document Type and Number:
WIPO Patent Application WO2006004968
Kind Code:
A3
Abstract:
Methods and apparatus for maximizing the capacity of serving cells (Cell A, Cell B) and minimizing inter-cell interferences due to power emission from serving cells (Cell A, Cell B) in a multi-carrier, multi-cell communication system (410) such as OFDMA or MC-CDMA. The control methods and apparatus take into account various factors such as cell configuration, frequency reuse, location and path-loss information, transmission priority (QoS), sub-channel configuration, feedback from other cells, or any combination thereof, and produce signals that control the transmission power levels and the modulation and coding scheme (MCS) of transmitted signal.
