METHOD AND WIRELESS COMMUNICATIONS SYSTEMS USING COORDINATED TRANSMISSION AND TRAINING FOR INTERFERENCE MITIGATION

摘要

A method for interference mitigation in a wireless communication system having multiple transmitters (15A, 15B, 15C) and receivers by introducing transmission time delays between the transmission of signals (S1, S2, and S3) from the individual transmitters (15A or 15B or 15C) to ensure coherent reception of the signals at a specific point (CD) in the coverage area. To further aid in interference mitigation the signals are assigned training patterns chosen to be distinguishable by the receiver and to optimize interference mitigation.
