Abstract: 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.

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 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.

Abstract: An outphasing calibration method in an outphasing calibration RF transmitter comprises detection of differences of a first plurality of signal characteristics of a first plurality of amplified RF signals across at least a transmitter antenna and a plurality of load impedances. The first plurality of amplified RF signals corresponds to a first plurality of constant-envelope signals. Accordingly, at least a generation of a second plurality of constant-envelope signals and at least one signal characteristic of each of a second plurality of constant-envelope RF signals on a plurality of transmission paths are controlled. At least one of a first calibration or a second calibration of a second plurality of signal characteristics of the second plurality of constant-envelope signals is executed based on the controlled generation of the second plurality of constant-envelope signals and the at least one controlled signal characteristic of each of the second plurality of constant-envelope RF signals.
