    Abstract: Systems and methods for enhancing coverage of repeater systems by time-division beamforming are provided. A repeater system includes an interface configured to communicate signals with a base station and a phased antenna array. The phased antenna array includes a plurality of antenna elements, wherein the phased antenna array is configured to generate a beam in a plurality of predefined directions and wirelessly communicate signals with user equipment in a coverage area of the phased antenna array. The repeater system further includes a beamforming circuit communicatively coupled to the phased antenna array, wherein the beamforming circuit is configured to adjust a direction of the beam generated by the phased antenna array to correspond to one of the plurality of predefined directions at a particular time according to a schedule.

    Abstract: In one embodiment, a RF signal repeater switchable between SISO and MIMO comprises: a controller; a first transmitter path switchably coupled to first donor and coverage antennas; a second transmitter path switchably coupled to second donor and coverage antennas; a first receiver path switchably coupled to the first donor and coverage antennas; a second receiver path switchably coupled to the second donor and coverage antennas. The controller configures the repeater for a MIMO TDD operating mode by: configuring the first transmitter path and the second receiver path to repeat at least a first MIMO channel of UE uplink RF signals and at least a first MIMO channel of base station downlink RF signals; and configuring the second transmitter path and the first receiver path to repeat at least a second MIMO channel of UE uplink RF signals and at least a second MIMO channel of base station downlink RF signals.
