Method of channel state information (csi) reporting in wireless communication system

A method of Channel State Information (CSI) reporting in a wireless communication system, the method comprising:

• receiving, with a user equipment (UE), CSI Reference Signals (CSI-RSs) from a base station (BS);
• calculating, with the UE, first parameters of Type I CSI and second parameters of Type II CSI based on the CSI-RS;
• and
• when different physical channels are used for reporting the Type I CSI and the Type II CSI reporting, respectively, reporting at least one of the Type I CSI and the Type H CSI to the BS,
• wherein the different physical channels are a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH).

• calculating, with the UE, first parameters of Type I CSI and second parameters of Type II CSI based on the CSI-RS;
• and
• scheduling, with the UE, Type I CSI and Type II CSI to avoid collision between Type I CSI reporting and Type II CSI reporting;
• and
• reporting, from the UE to the BS, the Type I CSI and Type II CSI.
