Abstract: A system, in an active reflector device, adjusts a first amplification gain of each of a plurality of radio frequency (RF) signals received at a receiver front-end from a first equipment via a first radio path of an NLOS radio path. A first phase shift is performed on each of the plurality of RF signals with the adjusted first amplification gain. A combination of the plurality of first phase-shifted RF signals is split at a transmitter front-end. A second phase shift on each of the split first plurality of first phase-shifted RF signals is performed. The plurality of RF signals as a directed beam is transmitted to a second equipment via a second radio path of the NLOS radio path.

Abstract: A system, in a programmable active reflector (AR) device associated with a first radio frequency (RF) device and a second RF device, receives a request and associated metadata from the second RF device via a first antenna array. Based on the received request and associated metadata, one or more antenna control signals are received from the first RF device. The programmable AR device is dynamically selected and controlled by the first RF device based on a set of criteria. A controlled plurality of RF signals is transmitted, via a second antenna array, to the second RF device within a transmission range of the programmable AR device based on the associated metadata. The controlled plurality of RF signals are cancelled at the second RF device based on the associated metadata.

Abstract: An active repeater device includes a primary sector and at least a secondary sector communicatively coupled to the primary sector receives or transmits a first beam of input RF signals having a first beam pattern from or to a base station, respectively. The primary sector includes an baseband signal processor and a first radio head (RH) unit. The secondary sector comprises a second RH unit. The first beam pattern covers a first geographical area. Beamforming coefficients are generated to convert the first beam pattern of the first beam of input RF signals to a second beam pattern. A second beam of output RF signals in the second beam pattern is transmitted from or received by, respectively, the secondary sector to or from, respectively, a plurality of user equipment (UEs) based on the generated beamforming coefficients and the received first beam of input RF signals.

Abstract: An active repeater device includes a primary sector and one or more secondary sectors, receives a first beam of input RF signals. A first set of analog baseband signals, are generated based on received first beam of input RF signals. The first set of analog baseband signals are converted to a first set of coded data signals and control information is extracted from the first set of coded data signals by decoding only a header portion of the first set of coded data signals without demodulation of data portion of the first set of coded data signals. Based on the extracted control information, the first set of coded data signals are transmitted as beams of output RF signals to remote user equipment. The transmission is independent of demodulation of the data portion within the active repeater device to reduce latency for transmission of the first set of coded data signals.

Abstract: A communication device includes a first lens and a feeder array. The first lens has a defined shape, a base, a first tubular membrane connected to the base, and a second membrane arranged as a cap on the first tubular membrane. The feeder array includes a plurality of antenna elements that are positioned in a specified proximal distance from the base of the first lens to receive a first lens-guided beam of input radio frequency (RF) signals through the second membrane of the first lens. The first lens of the defined shape covers the feeder array as a radome enclosure. A distribution of a gain from the received first lens-guided beam of input RF signals is substantially equalized across the feeder array to increase at least a reception sensitivity of the plurality of antenna elements of the feeder array.
