Abstract
A method and system for controlling PRB allocation in dual-connectivity service in which a first access node serves a UE on a first carrier concurrently with a second access node serving the UE on a second carrier. In an example implementation, the first and second access nodes interwork with each other to select a pair of (i) a first group of PRBs within the first carrier for uplink transmission from the UE to the first access node and (ii) a second group of PRBs within the second carrier for uplink transmission from the UE to the second access node, with the selecting being based on minimizing a maximum-power-reduction (MPR) that would be applied for concurrent transmission by the UE to the first access node and to the second access node. The access nodes could then accordingly coordinate the UE's concurrent uplink transmissions.
