Reference signaling design and configuration

A non-transitory computer readable medium having code stored thereon, the code when executed by a processor, causing the processor to implement a method, comprising:

• determining, by a communication device, one or more channel status information reference signal resources;
• receiving, by the communication device, channel status information reference signal on the one or more channel status information reference signal resources;
• and
• reporting, by the communication device, to a communication node, channel state information including first information about one set of first type of vectors shared by all layers, second information about one or more sets of second type of vectors, and third information corresponding to D time domain units,
• wherein each set of the one or more sets of second type of vectors is specific to one layer,
• wherein the first information, the second information and the third information for all of the D time domain units are same,
• wherein each of the first type of vectors includes P/2 elements, wherein P is a number of channel status information reference signal ports of one of the one or more channel status information reference signal resources, each second type of vector includes C elements each of which corresponds to one frequency domain unit,
• wherein each of C and D is a positive integer, or at least one of C or D is a positive integer larger than 1.
