Abstract: An example communication method includes determining, by a terminal device, M second switching delays, wherein a jth second switching delay is a delay for switching by the terminal device between a first frequency band group and a second frequency band group, the jth second switching delay is one of the M second switching delays, the first frequency band group and the second frequency band group each comprise at least one frequency band, and M is a positive integer. The terminal device can send third information to a network device, wherein the third information comprises the jth second switching delay.

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.
