Abstract: A method for estimating a position of an object comprises: receiving a motion event signal indicating a motion type of the object, the motion type being determined based on sensing data provided by one or more sensors; receiving one or more ranging measurements for distances between the object and one or more anchor points from a ranging device; determining a mode among a plurality of positioning modes based on the motion event and the one or more ranging measurements; and estimating a position of the object using the determined mode.

Abstract: A method and apparatus of a BS in a wireless communication system is provided. The method and apparatus comprises: storing a set of beam codebooks including a plurality of angular grids each of which is identified as a first type of angular grid or a second type of angular grid; identifying a set of parameters to adjust an antenna beam pattern based on the set of beam codebooks, wherein the set of parameters includes at least one of feedback information received from a UE or a set of KPIs identified by the BS; determining a type of angular grid as the first type of angular grid or the second type of angular grid, wherein the first and second type of angular grids include a first antenna gain and a second antenna gain, respectively; and select, from the set of beam codebooks, a beam codebook corresponding to the antenna beam pattern.

Abstract: A method and device for estimating the position of a moving object associated with a user. The estimation includes receiving an acceleration signal and an orientation signal, receiving ranging measurements, generating step size and heading information based on the acceleration signal and the orientation signal, and determining the position of the object based on the ranging measurements and the step size and heading information.

Abstract: A method for estimating a position of a moving object comprises: storing one or more reference position estimates for the moving object in a first buffer; storing step information in a second buffer, the step information including one or more step sizes and one or more step headings; receiving a motion event signal indicating the moving object moves continuously with a bounded direction; correcting the step information based on the one or more reference position estimates in response to receiving the motion event signal; and estimating the position of the moving object using the corrected step information.
