Abstract
Embodiments of the present disclosure relate to a method for precoding, a network device and a computer readable storage medium. For example, at a network device configured with a plurality of antennas and configured to operate in a plurality of frequency bands, channel state information (CSI) and an indication of a plurality of CSI accuracies corresponding to the CSI are obtained from a plurality of terminal devices. The bandwidth of the plurality of frequency bands is divided into one or more frequency band ranges based on comparison of each CSI accuracy with a first threshold accuracy, and ordering and precoding are performed, based on the CSI, on a plurality of data to be transmitted to the plurality of terminal devices within each frequency band range. Within each frequency band range, the plurality of precoded data is transmitted to the plurality of terminal devices via the plurality of antennas.
