    Abstract: Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to transceivers and receivers for wireless communications are described. The various aspects include an apparatus of a communication device including one or more antennas configured to receive an RF signal and an ADC system. The ADC system includes a 1-bit ADC configured to receive the RF signal, and an ADC controller circuitry configured to measure a number of positive samples in the received RF signal for a plurality of thresholds of the 1-bit ADC, estimate receive signal power associated with the received RF signal based on the measured number of positive samples, determine a direct current(DC) offset in the received RF signal using the estimated received signal power, and adjust the received RF signal based on the determined DC offset.

    Abstract: Aspects of mmWave beam tracking and beam sweeping are described, for example, spatial searching operations, directional beam forming, complex channel measurement operations, and adaptive power savings. Some aspects include using priori information for mmWave beam tracking and beam sweeping. Some aspects include using priori information to modify a superset of beam criteria to obtain a subset of beam criteria, select a spatial region according to the subset of beam criteria, and initiate a spatial searching operation within the spatial region for establishing a communication link. Some aspects include obtaining complex channel measurements of beams and combining the measurements with priori information to determine a beam for use in a communication link. Some aspects include providing signals from Nr over K1 input/output (IO) links and receiving signals over K1 IO

    Abstract: Aspects of mmWave beam tracking and beam sweeping are described, for example, an apparatus can include an antenna array including sub-arrays and processing circuitry configured to perform beamforming, beam tracking, and management thereof at the antenna sub-arrays. The processing circuitry can further be configured to determine the angle of arrival of a received signal received in response to performing the beamforming function and adjust phase shifters of the apparatus according to the angle of arrival. Other apparatuses, systems and methods are described.

    Abstract: Disclosed are apparatuses for a communication device. An apparatus for a communication device includes control circuitry configured to use circular convolution for pulse shape filtering of a block of data symbols of a single carrier waveform to generate a block-wise single carrier (BWSC) symbol. The apparatus is also configured to insert one of a data-based cyclic prefix or a data-based cyclic postfix into the BWSC symbol one of before the pulse shape filtering or after the pulse shape filtering. An apparatus for a communication device includes control circuitry configured to remove one or more of a cyclic prefix or a cyclic postfix from a received BWSC symbol, and use circular convolution to demodulate the received BWSC symbol.
