  • Patent number: 7181176
    Abstract: Data is to be transmitted from one transmitting point to multiple reception points in a wireless communication system. A transmitting antenna array has multiple antenna elements at the one transmitting point. Channel information is measured for each antenna element at each reception point. Antenna adjustments are determined using the measured channel information. The measured channel information from all of the users is correlated to determine weighting factors for each antenna element. The weighting factors to a point to multiple point transmission are applied prior to being radiated by each antenna element.
