Abstract: 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.
