1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one processor and the computer program code configured to, with the at least one processor, cause the apparatus to:
group columns of a linear combination coefficient matrix into a predefined number of clusters;
assign an index to each of the clusters based on a priority criterion, wherein lower indices are assigned for higher priority clusters;
send at least one of the clusters in a second part of an uplink control signalling transmission of a channel to an access node, wherein the uplink control signalling transmission comprises a first part and the second part; and
wherein the priority criterion comprises at least one of:
an average amplitude of linear combination coefficients per cluster; and
indices of the frequency domain components associated to the linear combination coefficients.
