Abstract: To control UE assumption of interference there is a controller module to control a plurality of transmission points, each constituted by a set of at least one transmit antenna, to transmit data to another device in a coordinated transmission from at least a subset of the plurality of transmission points. The controller module is configured to allocate, to each resource linked to the subset of the plurality of transmission points, an interference contribution parameter that is indicative of an expected interference contribution originating from said transmission point, and to inform said another device of those resources to which the subset of the plurality of transmission points is linked, together with the respective interference contribution parameter allocated to each resource. Another device reports feedback based on signals which are scaled with the respective interference contribution parameter.
