Abstract
A method of transmitting information between a transmitting station having an adaptive antenna array and a receiving station in a wireless communication system. The method includes the steps of generating default weight vectors for the antenna array of the transmitting station, transmitting the weight vector to the receiving station, modifying the weight vector in the receiving station, re-transmitting the modified weight vector to the transmitting station, and adapting the adaptive antenna array according to the modified weight vector within the transmitting station.

- b) transmitting the weight vectors to the receiving station;
- c) modifying the weight vectors in the receiving station;
- d) re-transmitting the modified weight vector of the transmitting station to the transmitting station;
- e) adapting the adaptive antenna array according to the modified weight vector within the transmitting station.
A transceiver station for communication within a wireless communication system comprising:
- an adaptive antenna array comprising a plurality of antenna elements for communication with another transceiver station;
- a controller for receiving and transmitting a digitized data stream coupled with the adaptive antenna array for receiving a data stream from the antenna array transmitted by said another transceiver station, wherein the data stream includes weight vector information;
- a weight modification unit within the controller for modifying the received weight vector information, wherein the controller retransmits the modified weight vector information to said another transceiver station.
