Abstract
Embodiments of the present disclosure relate to methods, devices and computer readable mediums for a unified nonlinear precoding procedure. The method comprises generating sequences of OFDM symbols on subcarriers on a downlink channel from the network device to a terminal device; determining a processing matrix of the downlink channel at least partially based on characteristics of the downlink channel; obtaining reference values of parameters of a signal generation model; and iteratively performing the following for a number of times: adjusting, based on the sequences of OFDM symbols and the processing matrix, the reference values of the parameters of the signal generation model, the parameters being signals for transmitting via transmitting ports of the network device on the downlink channel to the terminal device; and updating the reference values of the parameters of the signal generation model by clipping the adjusted values of the parameters of the signal generation model.
