Samsung patents method to optimize 5G signal routing using math

Samsung describes a system for wireless base stations that calculates the best way to send data to a phone. It analyzes the signal path using complex math, including Fourier transforms, to pick the most efficient transmission settings from a predefined list.

Why it mattersThis improves how efficiently data is sent over wireless networks, which is a standard part of maintaining fast and stable mobile connections.

In the filing’s own words

A device of a digital unit (DU) is provided. The device includes a transceiver, memory, comprising one or more storage media, for storing instructions, and one or more processors communicatively coupled to the transceiver and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the device to obtain a channel frequency response through reference signals from a terminal, obtain eigenvectors through eigen decomposition for the channel frequency response, obtain transform vectors by performing a two-dimensional Fourier transform on the eigenvectors, identify basis vectors among a plurality of basis vectors for an enhanced Type 2 codebook through a decision metric according to the transform vectors, determine a precoding matrix using the identified basis vectors, and transmit downlink data to which the precoding matrix is applied to the terminal through a radio unit (RU).

What exactly they claim (claim 1)

1. A device of a digital unit (DU), comprising: a transceiver; memory, comprising one or more storage media, storing instructions; and one or more processors communicatively coupled to the transceiver and the memory, wherein the instructions cause, when executed by the one or more processors individually or collectively, cause the device to: obtain a channel frequency response through reference signals from a terminal, obtain eigen vectors through eigen decomposition for the channel frequency response, obtain transformation vectors by performing a two-dimensional (2D) Fourier transform on the eigen vectors, identify basis vectors among a plurality of basis vectors for an enhanced Type 2 codebook through a decision metric according to the transformation vectors, determine a precoding matrix using the identified basis vectors, and transmit, through a radio unit (RU) to the terminal, downlink data to which the precoding matrix is applied.
