METHOD AND SYSTEM FOR MANAGING COMMUNICATION IN AN OFDMA SYSTEM

摘要

The present invention provides methods and system for managing communication in an orthogonal frequency division multiple access (OFDMA) system. The method comprises setting at least a first segment as a high power segment for a plurality of base station in the OFDMA system. Further, communication is established between at least one base station and at least one communication device in the OFDMA system, in response to setting the at least first segment as a high power segment. The method further comprises assigning a region of the first segment to a set of base stations in the OFDMA system. The assigned region can be used by the set of base stations at high power level to communicate with communication devices located in overlapping areas. A method for coordinating uplink transmission in the OFDMA system for reducing uplink interference is also provided.
