Abstract
The present disclosure provides a method implemented in an MCE for performing downlink power control for a multicast or broadcast service which is collectively provided from a number of radio base stations to a number of terminal devices. The method comprises collecting path-loss attenuations between the radio base stations and all or a subset of the terminal devices. The method further comprises calculating transmission powers for the radio base stations based on the collected path-loss attenuations, such that a sum of the transmission powers is minimized under a set of constraints on reception powers at said all or said subset of the terminal devices. Each of the radio base stations is notified of a corresponding one of the calculated transmission powers. The present disclosure also provides an MCE for performing downlink power control for a multicast or broadcast service.
