摘要： 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.

摘要： An array of antenna elements is energized as a plurality of concentric rings of the antenna elements, each of the concentric rings energized with a respective signal from a first transceiver, the signal having a continuously varying progressive phase between the antenna elements to generate n respective electromagnetic orbital angular momentum (OAM) beams each having a respective OAM mode m where m ranges from 0 to ±n. The beams are contemporaneously generated orthogonal to each other. The circumferential phase profile of the signal for a concentric ring of α antenna elements is 2πm radians, and the progressive phase difference between each of the α antenna elements is 2πm/α radians. The first transceiver transmits the beams to a second transceiver which demodulates them and sends demodulation quality information to the first transceiver for determination of whether to transmit the beams in full multiplexing, full diversity or partial diversity.
