BEAMFORMING PREDICTION DEVICE, METHOD AND PROGRAM - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18020572 Titled 'BEAMFORMING PREDICTION DEVICE, METHOD AND PROGRAM'

Simplified Explanation

The present disclosure describes a device that performs beamforming, which is a technique used in wireless communication systems to improve signal quality, taking into account the dynamic environment in which a user is moving. The device includes a storage unit that stores a dictionary and a fingerprint database based on user trajectories. It also includes a trajectory prediction unit that calculates the movement path of a mobile terminal using its location information. A fingerprint estimation unit applies the trajectory to the dictionary and calculates sparse coefficients corresponding to the trajectory. Finally, a beamforming calculation unit uses the sparse coefficients and the fingerprint database to calculate the beamforming for the mobile terminal.

Original Abstract Submitted

The present disclosure is to perform beamforming corresponding to the influence of a dynamic environment in which a user moves. The present disclosure relates to a beamforming prediction device that includes: a storage unit that stores a dictionary D obtained by learning fingerprints based on trajectories, and a fingerprint database based on trajectories; a trajectory prediction unit that calculates a trajectory of a mobile terminal, using location information about the mobile terminal; a fingerprint estimation unit that applies the trajectory of the mobile terminal to an input of the dictionary D, and calculates the sparse coefficient X corresponding to the trajectory of the mobile terminal; and a beamforming calculation unit that calculates beamforming of the mobile terminal, using the sparse coefficient X calculated by the fingerprint estimation unit and the fingerprint database.
