[0230] Example 5

[0231] Example 5 exemplifies a flowchart of the transmission of the first channel information included in the target CSI according to an example of the present application, as shown in the appendix Figure 5 shown. In the appendix Figure 5 , the first reference decoder is optional.

[0232] In Example 5, the first encoder and the first reference decoder belong to the first node; the first decoder belongs to the second node.

[0233] In Example 5, the first generator includes a first encoder. The first channel input generates first channel information through the first encoder. The target CSI includes the first channel information. The first encoder is obtained through training; the second node uses the first decoder to generate a first channel recovery. Among them, the input of the first decoder includes the first channel information, and the first decoder is obtained through training.

[0234] The first encoder and the first decoder should theoretically be inverse operations to ensure that the first channel input is the same as the first channel recovery.

[0235] As an example, due to factors such as implementation complexity, implementation fairness, air interface overhead, or latency, the first encoder and the first decoder in Embodiment 5 cannot ensure complete cancellation, so the first channel input and the first channel recovery cannot ensure being exactly the same.

[0245] As an example, the first receiver further includes a first reference decoder, the input of the first reference decoder includes the first channel information, and the output of the first reference decoder includes a first monitoring output.

[0246] As an example, the error between the first channel input and the first monitoring output is used by the first node to determine whether the first encoder needs to be updated.

[0247] In the above embodiments, the first reference decoder and the first decoder may be independently generated or independently maintained. Therefore, although their purposes are both to perform the inverse operation of the first encoder, the two may only be approximate.

[0248] As an embodiment, the training of the first encoder is performed at the first node.

[0249] As an embodiment, the training of the first encoder is performed at the second node, and the second node configures the first encoder to the first node.
