1. A wireless communication method, comprising:
sending, by a terminal device, a Media Access Control (MAC) Control Element (CE) to a network device through a Msg3 in a four-step random access procedure, wherein the MAC CE is used to indicate beam failure information corresponding to each secondary cell in at least one secondary cell;
wherein the method further comprises:
triggering, by the terminal device, a Scheduling Request (SR),
wherein triggering, by the terminal device, the SR, comprises: triggering, by the terminal device, the SR on a pre-configured first resource;
wherein the SR is used to request an uplink resource for transmitting the MAC CE;
wherein the beam failure information corresponding to each secondary cell comprises at least one of the following:
identity information of the secondary cell;
information of a target reference signal that corresponds to the secondary cell and satisfies a specific condition, wherein the target reference signal is a candidate reference signal which is used for a Beam Failure Recovery (BFR) for the secondary cell and is selected by the terminal device from a candidate reference signal set corresponding to the secondary cell; or
information indicating that there is no candidate reference signal for the secondary cell that satisfies the specific condition;
wherein the information of the target reference signal comprises a type of the target reference signal and an identity (ID) of the target reference signal, and the type of the target reference signal is a Synchronization Signal Block (SSB) or a Channel State Information Reference Signal (CSI-RS),
wherein a filed is provided in the MAC CE to indicate the type of the target reference signal, the field is set to 1 for an SSB ID, and the field is set to 0 for a CSI-RS ID;
wherein a logical channel priority of the MAC CE for indicating beam failure information corresponding to each secondary cell in at least one secondary cell is higher than a logical channel priority of data on any logical channel except an uplink Common Control Channel (CCCH).
