1. A first device comprising:
at least one processor; and
at least one memory including computer program codes;
the at least one memory and the computer program codes are configured to, with the at least one processor, cause the first device to:
receive, from at least one second device, a first reference signal on an uplink channel;
determine a first channel information on the uplink channel based at least in part on the reference signal using a data processing model;
determine a difference between the first channel information and a second channel information estimated based on the reference signal;
recover a third channel information on a downlink channel from a feedback signal from the at least one second device using the data processing model; and
update the data processing model based on the difference and the third channel information.
