Latest Patents

One of Heunchul Lee's latest patents is titled "Dynamic labeling for machine learning models for use in dynamic radio environments of a communications network." This invention outlines methods and nodes in a communications network that utilize a machine learning model trained with data from a first radio environment. The model is designed to adapt to a second radio environment by employing a first set of features as input and outputting a label based on a first labeling scheme. The method includes obtaining a dataset in the second environment, labeling each data point, and determining the suitability of the first labeling scheme. If deemed unsuitable, the method further involves determining a second labeling scheme using an unsupervised labeling method.

Another notable patent is the "Beamforming technique using approximate channel decomposition." This invention describes a method, system, and apparatus for beamforming techniques that leverage approximate channel decomposition. It involves a wireless device equipped with processing circuitry that utilizes a non-constant modulus (NCM) precoder from an NCM codebook to transmit on a physical channel. The NCM codebook is based on a constant modulus (CM) codebook and a series of NCM component matrices, which are derived from mathematical expressions. The invention aims to improve the performance of wireless communications.
