Samsung patents method to manage power in wireless repeaters

This patent describes a way for network-controlled repeaters to handle two simultaneous uplink signals that overlap in time. The system checks if the combined power of these signals exceeds a set limit and automatically adjusts the power levels to stay within that limit.

Why it mattersThis is a routine technical improvement for managing signal strength in cellular infrastructure, ensuring stable connections without hardware upgrades.

In the filing’s own words

Apparatuses and methods for prioritization of uplink transmissions by repeaters. A method for a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity, first information for a first uplink transmission by the NCR-MT entity and second information for a second uplink transmission by an NCR forward (NCR-Fwd) entity that overlap in one or more symbols. The method further includes identifying a power limit for simultaneous transmission by the NCR-MT and NCR-Fwd, determining first and second powers for the first and second uplink transmissions, respectively, and when a sum of the first and second powers in the one or more symbols exceeds the power limit, third and fourth powers for the first and second uplink transmissions, respectively, that do not exceed the power limit. The method further includes transmitting, in the one or more symbols, the first and second uplink transmissions with the third and fourth powers, respectively.

What exactly they claim (claim 1)

1. A method for a network-controlled repeater (NCR) in a wireless system, the method comprising: receiving, by an NCR mobile termination (NCR-MT) entity: first information for a first uplink transmission by the NCR-MT entity on a control link (C-link) of the NCR, and second information for a second uplink transmission by an NCR forward (NCR-Fwd) entity on a backhaul link (BH-link) of the NCR, wherein the second uplink transmission overlaps with the first uplink transmission in one or more symbols; identifying, by the NCR-MT entity, a power limit for simultaneous transmission by the NCR-MT entity and by the NCR-Fwd entity; determining, by the NCR-MT entity: a first power for the first uplink transmission and a second power for the second uplink transmission, and in response to a sum of the first power and the second power in the one or more symbols exceeding the power limit, a third power for the first uplink transmission and a fourth power for the second uplink transmission, wherein a sum of the third power and the fourth power does not exceed the power limit; and transmitting, by the NCR-MT entity, the first uplink transmission with the third power in the one or more symbols; and transmitting, by the NCR-Fwd entity, the second uplink transmission with the fourth power in the one or more symbols.
