Working assumption on CSI feedback: Standardise a common feedback/signalling framework suitable for scenarios 1-4 that can support CoMP JT, DPS and CS/CB. Feedback scheme to be composed from one or more of the following, including at least one of the first 3 sub-bullets: feedback aggregated across multiple CSI-RS resources per-CSI-RS-resource feedback with inter-CSI-RS-resource feedback per-CSI-RS-resource feedback per cell Rel-8 CRS-based feedback Note that use of SRS may be taken into account when reaching further agreements on the above. Continue discussion/evaluation to RAN1#67 to decide whether to support: aggregated feedback (if so, which components) inter-CSI-RS-resource feedback. 3GPP CoMP WI进展汇报 （DL） Downlink reference signals Working assumption on DL RS: Same DMRS sequence generator as in Rel-10 is used. A UE can be semi-statically configured in a UE-specific manner, which initialization values for DMRS scrambling generator are available for dynamic selection. Initialization values can be configured to correspond to Rel-10 DMRS. FFS: Introduction of additional orthogonality for DMRS Working assumption on CSI-RS: Allow multiple non-zero-power CSI-RS resources to be configured to a Rel-11 UE by dedicated signalling at least for CSI feedback. Downlink control signalling Continue investigation of the signalling requirements of the CoMP framework at RAN1#67. 3GPP CoMP WI进展汇报 （UL） 上行的议程包括 7.5.4.1 Standardisation impact of UL CoMP 7.5.4.2 Uplink reference signals 7.5.4.3 Uplink power control 7.5.4.4 U
