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.

The first message includes configuration information of at least one first reference signal. The communication method also includes receiving a second message from the network device. The second message indicates an availability of at least one second reference signal, the at least one second reference signal has a quasi co-location (QCL) relationship with at least one synchronization signal/physical broadcast channel block (SSB), and the at least one first reference signal includes the at least one second reference signal. The communication method further includes receiving, from the network device and based on the configuration information and the second message, an available reference signal of the at least one second reference signal.
