1. A method of a User Equipment (UE), the method comprising:
generating a Channel State Information Reference Signal (CSI-RS) sequence, wherein:
the CSI-RS sequence is mapped within a resource within a UE-specific bandwidth which is part of a cell bandwidth of a cell,
the CSI-RS sequence is defined by a first set of indices including a first index,
a value of the first index is offset by an offset value from a corresponding value of a second index which indicates a position in the resource, and
the corresponding value of the second index is defined relative to a reference, in a frequency domain, that is common for each UE within the cell; and
receiving the CSI-RS sequence.
