<p>Means for controlling user equipment (UE) assumption of interference comprising a controller, configured 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 is configured to allocate, to each resource linked to the subset of the plurality of transmission points designated for transmission towards the another device, 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 designated for transmission towards the another device is linked, together with the respective interference contribution parameter allocated to each resource. Another device comprises a controller configured to report feedback, wherein the feedback signal is based on signals which are scaled with the respective interference contribution parameter allocated to the respective resource. A particular application is in coordinated multipoint transmission (CoMP) system, in which a user equipment determines a channel quality indicator (CQI) on the basis of an interference contribution parameter from a network node (eNB).</p> |
