摘要： The present invention provides a method, apparatus and a computer program product for feedback design of hierarchical coordinated multipoint transmission. The present invention includes obtaining, at a user equipment, a list including a predetermined number of cells, identifying, at the user equipment, a cooperation set of cells including the cell serving the user equipment, determining, at the user equipment, for each cell included in the list whether the cell belongs to the identified cooperation set of the user equipment, and if the cell belongs to the cooperation set of the user equipment, reporting a first predetermined set of parameters, and if the cell does not belong to the cooperation set of the user equipment, reporting a second predetermined set of parameters.

摘要： Exemplary methods and devices related to controlling user equipment assumption of interference are described. In particular, there is proposed a device, 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.
