Abstract
Apparatus, methods, and computer program products for improving precoding downlink signaling are provided. An example method may include determining one or more noise covariance parameters for a noise covariance report, the noise covariance parameters being associated with a noise covariance matrix for whitening. The example method further may include transmitting, to a base station, the noise covariance report including the one or more noise covariance parameters or a noise whitening matrix for the whitening, the noise covariance report being transmitted based on a transmission periodicity of one or more slots.

A method of wireless communication of a user equipment (UE), comprising:
- determining one or more noise covariance parameters for a noise covariance report, the one or more noise covariance parameters being associated with a noise covariance matrix for whitening;
- transmitting, to a base station, the noise covariance report including the one or more noise covariance parameters or a noise whitening matrix for the whitening, the noise covariance report being transmitted periodically based on a transmission periodicity of one or more slots;
- and
- receiving, from the base station, at least one signal, the at least one signal being precoded based on at least one whitened channel, the at least one whitened channel being associated with the one or more noise covariance parameters or the noise whitening matrix for the whitening.
