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： A communication device initiates beam acquisition in a receive-only mode. Beam reception is set to an omni mode in which different beams of RF signals are receivable at the communication device from different directions. A primary signal synchronization (PSS) search is executed from each signal synchronization block location. A received signal strength indicator (RSSI) for each beam of the plurality of different beams of RF signals for each SSB location is measured and the communication device switches to a specific beam of RF signals in a New Radio (NR) frequency that has a highest RSSI. The receive-only mode is deactivated and communication of the specific beam of RF signals in the NR frequency band to a customer premise equipment (CPE) or a user equipment (UE) is activated for low-latency non-standalone access to the beam of RF signals in the NR frequency band at the CPE or the UE.

摘要： A communication device includes a lens having a defined shape. A feeder array comprising a plurality of antenna elements that are positioned in a specified proximal distance from the lens to receive a lens-guided beam of input radio frequency (RF) signals through the lens. The specified proximal distance is less than a focal length of the lens. The lens covers the feeder array as a radome enclosure. A distribution of a gain from the received lens-guided beam of input RF signals is substantially equalized from a radiation surplus region to a radiation deficient region of the feeder array to increase at least a reception sensitivity of the plurality of antenna elements for at least the lens-guided beam of input RF signals, based on the defined shape of the lens and the specified proximal distance of the feeder array to the lens.

摘要： A device includes a primary sector and secondary sectors communicatively coupled to the primary sector. The processor included in the primary sector is configured to down convert a Radio Frequency (RF) signals with a first frequency to an analog baseband (IQ) signal with a second frequency, and receive a second digital baseband signal that comprises a first digital baseband signal and a digital echo signal. The first digital baseband signal comprises a training sequence signal. Further, the processor estimates a plurality of filter taps of the FIR filter based on the digital echo signal and estimate the digital echo signal in the received second digital baseband signal based on the first digital baseband signal and the plurality of filter taps of the FIR filter. The estimated digital echo signal is removed from at least one current digital baseband signal based on the down conversion of the RF 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. 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.
