Abstract:
1. A communications apparatus, comprising: a source of data; a transmitter circuit coupled to the source of data for generating a plurality of data signals each data signal including the same data, the plurality of data signals including a first data signal and a second data signal the first and second data signals differing from one another as a function of time by at least one of a phase and an amplitude, the transmitter circuit including means for independently varying the phase of at least one of the first and second data signals as a function of time; a plurality of antennas coupled to said transmitter circuit to receive and transmit said data signals in parallel, each antenna receiving and transmitting one of said data signals; a receiver for receiving communications channel condition information from a plurality of mobile stations regarding the condition of a communications channel associated with individual ones of said plurality of mobile stations; means for scheduling transmission of data to individual mobile stations as a function of the received communications channel condition information wherein the means for scheduling includes a scheduling routine which gives preferential treatment to the scheduling of data transmissions to mobile stations with good communications channels as compared to mobile stations with poorer communications channels; and means for determining the rate at which data should be transmitted in said first and second data signals as a function of the communications channel information.
