Samsung patents method to adjust phone signal strength by frequency slice

Patent drawing
Patent drawing from the official filing.

Samsung describes a way for cell towers to manage how hard phones push their signals during 5G or 6G connections. The system splits the available radio space into smaller frequency sections and tells each phone exactly how much power to use in each section.

Why it mattersThis could help reduce interference between neighboring cell towers and improve data speeds for users standing at the edge of a coverage area.

In the filing’s own words

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present invention relates to the field of communications. The proposed method of frequency-selective control of a power of an uplink channel transmission includes dividing an available frequency band into a plurality of sub-bands to be used in the frequency-selective power control of UL transmissions, determining transmit power adjustment values for each sub-band obtained by dividing, and signalizing the determined sub-bands obtained by dividing and the corresponding transmit power adjustment values for these sub-bands for their subsequent application, which, as a result, provides at least the reduction in inter-cell interference and the performance gain of the user terminals located close to cell edges.

What exactly they claim (claim 1)

1. A transmission-reception point (TRP) in a wireless communication system, the TRP comprising: a transceiver; and a controller coupled with the transceiver, and configured to: divide an available frequency band into a plurality of sub-bands, wherein the plurality of sub-bands is associated with an uplink (UL) channel with a frequency-selective transmit power control, identify a transmit power adjustment value for adjusting a power in a sub-band among the plurality of sub-bands, transmit, to a user equipment (UE), an indication for the plurality of sub-bands, wherein the indication indicates the transmit power adjustment value, and receive, from the UE, the UL channel with a frequency-selective power adjustment based on the indication.
