Information feedback method, terminal and network side equipment

Provided are an information feedback method, terminal and network side device, relating to the technical field of communications, the method comprising: encoding channel state information at a first moment and channel state information at a second moment through a first encoding model to obtain first feedback information, the second moment is at least one moment before the first moment, and the first feedback information is incremental feedback of the channel state information at the first moment relative to the channel state information at the second moment; and sending the first feedback information to network side equipment. According to the embodiment of the invention, the effect of compressing the channel state information can be improved. 本发明提供一种信息反馈方法、终端及网络侧设备，涉及通信技术领域，其中，所述方法包括：通过第一编码模型对第一时刻的信道状态信息及第二时刻的信道状态信息进行编码处理，获得第一反馈信息，其中，所述第二时刻为所述第一时刻之前的至少一个时刻，所述第一反馈信息为所述第一时刻的信道状态信息相对于所述第二时刻的信道状态信息的增量反馈；向网络侧设备发送所述第一反馈信息。本发明实施例能够提高对信道状态信息进行压缩的效果。
