Apparatuses, methods, and systems are disclosed for reporting a UE-selected parameter combination for reciprocity-based Type-II CSI codebook. One apparatus includes a processor and a transceiver that receives a CSI reporting configuration from a mobile communication network, the reporting configuration containing a codebook configuration. The processor identifies a set of antenna ports based on a received set of CSI reference signals and generates at least one coefficient amplitude indicator and one coefficient phase indicator for each antenna port in the identified set of antenna ports. The processor selects a subset of at least one parameter combination from a set of two or more parameter combinations corresponding to the codebook configuration and sends a CSI report to the mobile communication network, the CSI report indicating the selected parameter combination.

CSI reporting with parameter combination selection

Apparatuses, methods, and systems are disclosed for channel state information reporting for multiple transmit/receive points. One apparatus includes a transceiver that receives an indication from a mobile wireless communication net-work that channel state information ('CSI') corresponding to multiple transmit/receives points (“TRPs”) is to be reported and a processor that generates at least one CSI report according to the CSI reporting configuration, the at least one CSI report comprising a CSI-reference signal (“CSI-RS”) resource indicator (“CRI”), wherein the transceiver reports the at least one CSI report comprising the CRI to the mobile wireless communication network.
