Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may perform channel state information (CSI) measurements on one or more reference signal transmissions from a base station; determine, based at least in part on the CSI measurements, a set of non-zero linear combination complex coefficients for weighting and co-phasing for a linear combination of a plurality of frequency domain basis vectors and a plurality of spatial domain basis vectors; and transmit a CSI feedback, wherein a first part of the CSI feedback includes at least an indication of a number of the set of non-zero linear combination complex coefficients with regard to all layers of a communication link between the UE and the base station. Numerous other aspects are provided.
