Abstract:
A method of channel allocation for a K.sup.th communication connection via a radio interface in a mobile communication system with spatial subscriber separation comprising the steps of:providing at least K.sub.ges -1 communication connections in L channels for management via the radio interface;allowing K-1 communication connections in each channel, wherein l=1 . . . L;determining spatial covariance matrices C.sub.1.sup.(l), . . . , C.sub.K-1.sup.(l) for the existing K-1 communication connections;determining noise values N.sub.1.sup.(l), . . . , N.sub.K-1.sup.(l) for the existing K-1 communication connections;determining an anticipated noise value for the K.sup.th communication connection;determining an anticipated spatial covariance matrix C.sub.k.sup.(l) for the K.sup.th communication connection;determining an anticipated noise value N.sub.K.sup.(l) for the K.sup.th communication connection;determining an anticipated downlink transmission power P.sup.(I) for the l.sup.th channel with K communication connections in order to adhere to a required signal-to-noise ratio criterion;determining a decision value c.sup.(l) from a relationship of the anticipated downlink transmission power P.sup.(I) for the channel l and a reference transmission power (P.sup.(l)); andallocating the channel l having the lowest decision value c.sup.(l) to the K.sup.th communication connection.
