摘要： 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.

摘要： A network sends to a user equipment UE a reference signal configuration, and from receiving it the UE selects a codeword identifying a cooperative multipoint CoMP transmission scheme. There is a CoMP scheme selection codebook from which the UE selects the codeword corresponding to its recommended CoMP scheme. The UE sends to the network that codeword which identifies the CoMP transmission scheme, along with the CSI feedback characterizing the CoMP transmission scheme. From that codeword which the network receives it determines the UE's assumed CoMP transmission scheme, which the network uses to determine how the CSI feedback, received from the UE, was calculated by the UE (for example, joint transmission, or dynamic point selection with or without muting, or coordinating scheduling/beamforming). The network uses this information for selecting a CoMP transmission scheme for downlink CoMP transmissions to the UE.

摘要： For coordinated multipoint transmission arrangements there is provided a device, including a controller module, 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, wherein each subset with resources allocated thereto defines a respective coordinated transmission scheme, wherein the controller module is configured to transmit information on resources pertaining to multiple coordinated transmission schemes, and send at least one biasing parameter associated to at least one of the transmission schemes, to be applied for biasing a channel quality parameter. Another device includes a controller module, configured to report feedback responsive to such coordinated transmission, and the controller module is, among others, configured to apply the at least one biasing parameter to derived channel quality parameters.
