摘要： The invention relates to methods and arrangements in a transmitting node for enabling a receiving node to perform measurements on interference caused by transmissions from at least one transmission point controlled by the transmitting node on receptions at the receiving node. The transmitting and receiving nodes are comprised in a wireless communications system. The transmitting node determines an interference measurement resource, IMR, for the receiving node. The receiving node is expected to measure interference on the IMR. The transmitting node then transmits at least one interfering signal on the IMR. The at least one interfering signal is not expected to be decoded or coherently measured upon by any node served by the transmitting node.

摘要： A system and method for providing an eNodeB with the flexibility to configure a Channel State Information (CSI) report to match a specific Coordinated Multipoint (CoMP) transmission hypothesis, which is a candidate for a downlink transmission to a User Equipment (UE) is disclosed. A UE receives, from the eNodeB, a configuration message that specifies a CSI report. The CSI report is specified by a particular interference hypothesis and a particular desired signal hypothesis corresponding to data transmission over at least one effective channel characterized by a specific reference signal. The UE estimates interference according to the interference hypothesis, and/or estimates at least one effective channel by performing measurements on the specific reference signal, and determines a CSI report based on the interference estimation and on the estimated effective channel. The UE also transmits the CSI report to the eNodeB.

摘要： A system and method for improving the link adaptation in a wireless communication system is disclosed. User Equipment (UE) forms an interference hypothesis by amending a measured interference and noise by artificially injecting, to the measured interference and noise, interference corresponding to at least one emulated interfering isotropic signal that is virtually transmitted over an associated estimated effective channel. The UE further determines at least one channel state information (CSI) report based on the interference hypothesis, and transmits the CSI report to the network.

The Start method comprises transmitting, by said plurality of antennas, according to different CSI-RS transmit configurations and at different points in time, channel state information reference symbols, CSI-RS. At a first time instance a CSI report from at least one user equipment, UE, is received. Based on the CSI report being received at said first time instance, said received CSI report is associated with a specific CSI-RS transmit configuration of the different CSI-RS transmit configurations. A control node and a computer program are also disclosed.
