    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: An apparatus and a method for detecting data transmitted over a wireless channel are disclosed. For example, for each receive antenna of a plurality of receive antennas, the method converts, by an ADC, an analog signal received by the receive antenna to a respective digital signal, and for each receive antenna of the plurality of receive antennas, the method channel transforms, by a channel transformer, the digital signal to determine a respective equivalent integer representation of the digital signal, and the method detects data by receive combining, by a receive combiner, the respective equivalent integer representations of the digital signals determined for the plurality of receive antennas.

    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 an antenna array and processing circuitry coupled to the antenna array. The processing circuitry is configured to initialize a beam tracking algorithm based on received signals received at the antenna array, wherein antenna phases used in the beam tracking are bound by an upper phase limit and a lower phase limit, to generate a beam tracking result. The processing circuitry is further configured to generate a calibration vector based on the beam tracking result and receive subsequent transmissions using a codebook adapted based on the calibration vector.
