Abstract
Methods and systems having improved capabilities are described for providing communications to a plurality of cellular mobile devices through generating m different sets of fixed position patterns of N RF beams across four contiguous one-millisecond LTE sub-frames from an agile beam forming antenna system of a cellular LTE base transceiver station. The cellular LTE base transceiver station is in RF frequency division duplexing (FDD) communication with the plurality of cellular mobile devices within a cell coverage area of the cellular LTE base transceiver station. Each RF beam illuminates a non-contiguous sub-area of the cell coverage area. A number m sets of RF beam patterns illuminate the area of the cell coverage area, wherein 1≦m≦4.
