CSI FEEDBACK FOR SINGLE DCI BASED MULTI-TRP TRANSMISSION

Systems and methods for CSI feedback are provided. In some embodiments, a method performed by a UE for CSI feedback for Non-Coherent Joint Transmission (NC-JT) Physical Downlink Shared Channel (PDSCH) transmission from multiple Transmission/Reception Points (TRPs) includes: receiving a CSI reporting setting comprising: a set of NZP CSI-RS resources for channel measurement including a first and second NZP CSI-RS resource for channel measurement; and a set of CSI-IM resources including a first and second CSI-IM resource for interference measurement; measuring interferences based on the CSI-IM resources, where the interferences are considered different instances of a same interference if a same set of receive antennas are used, and the interferences are considered different interferences if different sets of receive antennas are used; and computing and reporting CSI feedback comprising: a NC-JT CSI and a first single TRP CSI; or a NC-JT CSI; or a CRI and a second single TRP CSI.
