1. A method performed by a wireless device for reporting channel state information (CSI) for a downlink channel, the method comprising:
transmitting a CSI report for the downlink channel to a network node, the CSI report comprising:
a set of reported coefficients;
an indication of how the network node is to interpret the set of reported coefficients, wherein the indication of how the network node is to interpret the set of reported coefficients indicates the set of reported coefficients as a subset of a set of candidate reported coefficients; and
an indication of a payload size of the set of the reported coefficients,
wherein:
in a quantization range for the set of reported coefficients, the amplitude quantization values are

and
these amplitude quanitization values are associated with the quantization indices 0, 1, 2, 3, 4, 5, 6 and 7, respectively.
