Abstract: THIS INVENTION RELATES TO A METHOD TO DYNAMICALLY ENHANCED THE PERFORMANCE OF DATA TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM AND MORE PARTICULARLY TO THE MULTIPLE INPUT MULTIPLE OUTPUT (MIMO) OF THE COMMUNICATION SYSTEM. THE METHOD PROPOSED BY THE PRESENT INVENTION INCLUDES CREATING FLEXIBLE PARAMETERS TO THE MULTI-ELEMENTS ANTENNA ARRAY AND UTILIZING OF SPACE TIME CODING (STC) AND SPATIAL MULTIPLEXING (SM) IN THE TRANSMISSION CRITERION AT THE BASE STATION (BS) (1). THE FLEXIBLE PARAMETERS ARE THE NUMBERS OF ANTENNA ELEMENTS N AND DISTANCE BETWEEN ELEMENTS D. THESE TRANSMISSION CRITERION AND MULTI-ELEMENTS ANTENNA ARRAY CHANGING ACCORDING TO FEEDBACK FROM THE RELAY STATIONS (RS) (2) AND THE RELAY STATIONS (RS) (2) ARE RECEIVING DATA FROM THE SUBSCRIBER STATIONS (SS) (3). FROM THE FEEDBACK FROM A PARTICULAR RELAY STATION (RS) (2), THE TRANSMISSION CRITERION SHALL DETERMINED EITHER TO USE SPACE TIME CODING (STC) OR SPATIAL MULTIPLEXING (SM) OR BOTH AND N AND D CHANGES ACCORDINGLY TO IMPROVE SIGNAL-TO-NOISE RATIO (SNR), BIT ERROR RATE (BER), DATA RATE, RELIABILITY ETC.

Abstract: THE PRESENT INVENTION RELATES TO A COOPERATIVE COMMUNICATION AMONG A PLURALITY OF BASE STATIONS (BSS) 10 AND 12 FOR SENDING DATA PACKETS TO SUBSCRIBER SERVER (SS) 30 THROUGH A PLURALITY OF RELAY STATIONS (RSS) 20, 22, 24, AND 26. THE PRESENT INVENTION RELATES TO A METHOD OF MAKING THE PLURALITY OF BASE STATIONS COOPERATE WITH EACH OTHER BY EXCHANGING INFORMATION ABOUT THE CURRENT UTILIZED RELAY STATIONS. THE SERVING BASE STATION UPDATES THE NEIGHBORING BASE STATIONS WITH THIS INFORMATION, THUS THIS COOPERATION IS ABLE TO MAXIMIZE THE USAGE OF THE FREE RELAY STATIONS. THE PRESENT INVENTION RELATES TO A METHOD TO REALLOCATE THE SOURCES (RELAY STATIONS) IN A MORE EFFICIENT MANNER, MEANS SUBSCRIBER STATION WITH HIGHER NEED IS BE ABLE TO UTILIZE THE FREE RELAY STATIONS TO FORWARD ITS SIGNAL COMING FROM THE SERVING BASE STATION.
