Abstract: A user equipment, a base station, a joint training device for a user equipment and a base station, a joint channel estimation and feedback system for a user equipment and a base station, a feedback channel state information generation method, a channel matrix generation method, a joint training method, and a joint channel estimation and feedback method for a user equipment and a base station in wireless communication. Feedback channel state information is generated by a user equipment according to an actual pilot signal, and a deeper residual learning neural network is introduced into a base station to reconstruct a channel matrix of the base station according to the feedback channel state information. As such, it is possible that the base station can reconstruct a complete high-resolution channel matrix even if an actually received pilot signal is an incomplete low-resolution part.
