A wireless communication method, wherein the wireless communication method is applied to a first wireless communications apparatus (400, 500), the first wireless communications apparatus (400, 500) is configured to have a plurality of wireless communication capabilities, and the method comprises: when the first wireless communications apparatus (400, 500) uses a first wireless communication capability to communicate with a second wireless communications apparatus, if the first wireless communications apparatus (400, 500) determines to adjust the wireless communication capability of the first wireless communications apparatus (400, 500), sending, by the first wireless communications apparatus (400, 500), first adjustment information to the second wireless communications apparatus, and starting a first timer, wherein the first adjustment information is used to indicate to adjust the wireless communication capability of the first wireless communications apparatus (400, 500) to a second wireless communication capability; within a specified time of the first timer, using, by the first wireless communications apparatus (400, 500), the second wireless communication capability to communicate with the second wireless communications apparatus, wherein the first wireless communication capability is any one of the plurality of wireless communication capabilities, and the second wireless communication capability is any one of the plurality of wireless communication capabilities except a maximum wireless communication capability and a minimum wireless communication capability; when the first wireless communication capability is the maximum wireless communication capability among the plurality of wireless communication capabilities, an absolute value of a difference between a first transmission rate and a second transmission rate is a first value; when the first wireless communication capability is a wireless communication capability other than the maximum wireless communication capability, the absolute value of the difference between the first transmission rate and the second transmission rate is a second value; and the first value is greater than the second value; and the first transmission rate is an upper limit of a transmission rate at which the first wireless communications apparatus uses the first wireless communication capability to communicate with the second wireless communications apparatus, and the second transmission rate is an upper limit of a transmission rate at which the first wireless communications apparatus (400, 500) uses the second wireless communication capability to communicate with the second wireless communications apparatus. when the first wireless communications apparatus (400, 500) uses a first wireless communication capability to communicate with a second wireless communications apparatus, if the first wireless communications apparatus (400, 500) determines to adjust the wireless communication capability of the first wireless communications apparatus (400, 500), sending, by the first wireless communications apparatus (400, 500), first adjustment information to the second wireless communications apparatus, and starting a first timer, wherein the first adjustment information is used to indicate to adjust the wireless communication capability of the first wireless communications apparatus (400, 500) to a second wireless communication capability; within a specified time of the first timer, using, by the first wireless communications apparatus (400, 500), the second wireless communication capability to communicate with the second wireless communications apparatus, wherein the first wireless communication capability is any one of the plurality of wireless communication capabilities, and the second wireless communication capability is any one of the plurality of wireless communication capabilities except a maximum wireless communication capability and a minimum wireless communication capability; when the first wireless communication capability is the maximum wireless communication capability among the plurality of wireless communication capabilities, an absolute value of a difference between a first transmission rate and a second transmission rate is a first value; when the first wireless communication capability is a wireless communication capability other than the maximum wireless communication capability, the absolute value of the difference between the first transmission rate and the second transmission rate is a second value; and the first value is greater than the second value; and the first transmission rate is an upper limit of a transmission rate at which the first wireless communications apparatus uses the first wireless communication capability to communicate with the second wireless communications apparatus, and the second transmission rate is an upper limit of a transmission rate at which the first wireless communications apparatus (400, 500) uses the second wireless communication capability to communicate with the second wireless communications apparatus.
