摘要： 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. Beamforming coefficients are generated to convert the first beam pattern of the first beam of input RF signals to a second beam pattern based on a location of each of a plurality of user equipment (UEs). 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, the plurality of UEs based on the generated beamforming coefficients and the received first beam of input RF signals.

摘要： A communication device includes a first lens, a feeder array, and control circuitry communicatively coupled to the feeder array. The first lens is associated with a defined shape, which further exhibits a defined distribution of dielectric constant. The feeder array includes a plurality of antenna elements that are positioned in proximity to the first lens. The control circuitry equalizes a distribution of a gain from the received first lens-guided beam of input RF signals across the feeder array and different scan directions of the plurality of antenna elements. The equalized distribution of gain is based on the defined distribution of dielectric constant within the first lens and the proximity of the feeder array to the first lens.

摘要： An active repeater device including a first antenna array, a controller, and one or more secondary sectors receives or transmits a first beam of input RF signals from or to, respectively, a first base station operated by a first service provider and a second beam of input RF signals from or to, respectively, a second base station operated by a second service provider. A controller assigns a first beam setting to a first group of customer premises equipment (CPEs) and a second beam setting to a second group of CPEs, based on one or more corresponding signal parameters associated with the each corresponding group of CPEs. A second antenna array of the second RH unit concurrently transmits or received a first beam of output RF signals to or from the first group of CPEs and a second beam of output RF signals to the second group of CPEs.

摘要： 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.

摘要： 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. A second amplification gain of each of the plurality of second phase-shifted RF signals is adjusted.
