Abstract: A decoding method includes: decoding first to-be-decoded information based on a first decoder to obtain a first decoding result that includes first soft information or a first hard output; and correcting the first decoding result based on a first correction model to obtain a corrected first decoding result of the first to-be-decoded information. The first correction model is obtained through training based on training data that includes a training decoding result and a corrected training decoding result. The training decoding result is a decoding result obtained after the first decoder decodes training to-be-decoded information, and the corrected training decoding result is a corrected decoding result corresponding to the training decoding result. In this way, after a decoder performs decoding, a decoding result can be corrected based on a correction model.

Abstract: In a cell handover method and apparatus, first network device of a first cell obtains user information of a terminal device, and then the first network device may determine handover information based on the user information and running information of the first network device, so that after the first network device sends an RRC message including the handover information to the terminal device, the terminal device may perform N consecutive cell handovers based on the handover information. In the N cell handovers, the first network device only needs to obtain the user information once, to configure handover conditions for the N subsequent handovers in advance at a time. This simplifies a network signaling procedure, reduces network overheads, and reduces handover response time. The embodiments of this disclosure are applicable to a network handover in a satellite scenario.
