Inventors include Zou, Gang; Sjland, Henrik; Torres, Florent; and Din, Imad Ud.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: A wireless device (WD) and method for low power millimeter wave (mmWave) receiving for beam tracking are disclosed. According to one aspect, a secondary WD is configured to receive an amplitude shift keying (ASK) modulated signal from a primary WD using at least three antenna branches of a low power receiver. In each antenna branch, the secondary WD down-converts the ASK modulated signal using a local oscillator signal from a free-running multi-phase oscillator applied in a multi-phase mixer to provide a multi-phase intermediate frequency signal. The secondary WD determines a beam direction of the ASK modulated signal by correlating phase adjusted combinations of the intermediate frequency signals from the antenna branches with a reference sequence and provides the beam direction to the a main receiver of the secondary WD. The beam direction may be used for an initial communication between the second receiver and the primary WD.
