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 this application provide a resource configuration method, an information sending method, and an apparatus. The resource configuration method includes: configuring, by a network device for a terminal device, a plurality of resources used to transmit uplink control information UCI; configuring, by the network device, same first indication information for all of the plurality of resources; and sending, by the network device, the first indication information to the terminal device, wherein the first indication information indicates the terminal device to multiplex first UCI and second UCI, and a type of the first UCI is different from a type of the second UCI. Therefore, the terminal device can determine whether to combine the first UCI and the second UCI.

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.
