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.

Abstract: One embodiment is directed to an open radio access network to provide wireless coverage for a plurality of cells at a site and that comprises a virtualized headend comprising one or more base-station nodes and a plurality of unified remote units deployed at the site. Each of the unified remote units is able to support multiple functional splits, multiple wireless interface protocols, multiple generations of radio access technology, and multiple frequency bands. The unified remote units and functional split used to serve each cell can be changed (for example, on-the-fly as a part of an automatic or manual adaptation process that is a function of one or more monitored performance attributes of the open radio access network such as network bandwidth, network latency, processing load, or processing performance). The unified remote units can be implemented in a modular manner with a backplane to which different radio modules can be coupled.
