Abstract: A wireless communication method and apparatus for improving communication failure recovery efficiency. The method is applied to a terminal or a chip used in a terminal, and includes: upon detecting that downlink communication of the first serving cell fails, determining that downlink communication of the second serving cell is normal; sending a communication failure recovery request on an uplink channel of the second serving cell, where the communication failure recovery request is used to request to recover from a downlink communication failure of the first serving cell; and detecting a communication failure recovery response on a downlink channel of the second serving cell, where the communication failure recovery response is used to indicate a downlink communication resource of the first serving cell.

Abstract: Embodiments of the present invention disclose a channel decoding method, apparatus, and system. The channel decoding apparatus includes a memory storing instructions; and a processor coupled to the memory to execute the instructions to: obtain decoding information of first channel decoding of a data block; determine whether the first channel decoding fails; in response to determining that the first channel decoding fails, obtain a reference sequence number of the data block; obtain at least one matching historical demodulated soft value; combine the demodulated soft value of the data block and the at least one matching historical demodulated soft value to obtain a combined demodulated soft value of the data block; and perform second channel decoding on the combined demodulated soft value of the data block.
