1. A method in a user equipment for generating a channel state information feedback report, the method comprising:
receiving a set of reference signals transmitted from a set of network entities;
computing a plurality of entries that are included in the channel state information feedback report based on the received set of reference signals, wherein:
the plurality of entries that are included in the channel state information feedback report include at least a set of coefficients; and
each coefficient is associated with a set of indices including at least one spatial domain basis index, at least one frequency domain basis index, and at least one layer index; and
arranging the plurality of entries that are included in the channel state information feedback report in an order known to both the user equipment and a network entity of the set of network entities, wherein:
higher prioritized entries are positioned toward a beginning of the order of the arranged plurality of entries and lower prioritized entries are positioned toward an end of the order of the arranged plurality of entries;
at least a portion of the channel state information feedback report includes one or more concatenated groups;
the plurality of entries that are included in the channel state information feedback report are prioritized using indices corresponding to the set of indices of the plurality of entries;
a subset of indices of the set of indices of the plurality of entries are permuted based on predefined permutations of spatial domain basis indices of the subset of indices;
a predefined permutation function of the predefined permutations of the spatial domain basis indices swaps a spatial domain basis index i* with a first spatial domain basis index and a spatial domain basis index mod2L(i*+L) with a last spatial domain basis index;
i* is the spatial domain basis index of a spatial domain basis containing a strongest coefficient;
L represents a total number of spatial domain basis indices; and
modq(r) represents a modulo operation of an integer r with respect to a positive integer q.
