Wireless communication method, wireless communications apparatus, and wireless communications system

A wireless communications apparatus, comprising:

• a processor and a receiver connected to the processor, wherein the receiver is configured to:
• receive downlink configuration information from a base station, wherein the downlink configuration information is used to indicate a configuration of a downlink control message, the configuration of the downlink control message comprises a format of the downlink control message, and the downlink control message is used to carry service data to be transmitted to a terminal;
• and
• receive the downlink control message from the base station based on the configuration of the downlink control message, wherein
• the configuration, indicated by the downlink configuration information, of the downlink control message further comprises:
• an identifier of a data radio bearer and a candidate air interface parameter corresponding to the data radio bearer, wherein
• the candidate air interface parameter is used to determine a detection region of the downlink control message, and the service data carried in the downlink control message belongs to the data radio bearer.
