7.2.6 Channel-State Information – Interference Measurement (CSI-IM) Resource definition
36.2133GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Physical layer proceduresRelease 17TS
For a serving cell and UE configured in transmission mode 10, the UE can be configured with one or more CSI-IM resource configuration(s). The following parameters are configured via higher layer signaling for each CSI-IM resource configuration:
– Zero-power CSI RS Configuration (see Table 6.10.5.2-1 and Table 6.10.5.2-2 in [3])
– Zero-power CSI RS subframe configuration . The allowable values are given in Clause 6.10.5.3 of [3].
For a serving cell, if a UE is not configured with the higher layer parameter csi-SubframePatternConfig-r12, the UE is not expected to receive CSI-IM resource configuration(s) that are not all completely overlapping with one zero-power CSI-RS resource configuration which can be configured for the UE.
A UE is not expected to receive a CSI-IM resource configuration that is not completely overlapping with one of the zero-power CSI-RS resource configurations defined in Clause 7.2.7.
For a serving cell, if a UE is not configured with CSI subframe sets and for any CSI process, and the UE is configured with four CSI-IM resources, then the UE is not expected to be configured with CSI processes that are associated with all of the four CSI-IM resources.
A UE should not expect the configuration of CSI-IM resource and PMCH in the same subframe of a serving cell.
