Embodiments of the present invention provide a bandwidth adjustment method, a bus controller, and a signal convertor. The method includes: obtaining, by a bus controller, a first frequency and a first channel number; sending a bandwidth negotiation request carrying the first frequency and the first channel number to a bus controller of a first peer end to determine whether or not the bus controller of the first peer end is capable of controlling a physical component of the first peer end to receive data via a channel corresponding to the first channel number according to the first frequency; and receiving a negotiation result sent by the first peer end and controlling the physical component to transmit data according to the negotiation result. In the technical solutions of the embodiments of the present invention, bandwidth adjustment is flexible and the loss of data is avoided. |

1. A bandwidth adjustment method, comprising:
obtaining a target bandwidth value; obtaining, by a bus controller, a first frequency and a first channel number according to the target bandwidth value, wherein the target bandwidth value is equal to a product of a valid payload, the first frequency, and the first channel number, wherein the target bandwidth value is expressed by the formula M=k*f*N, where M indicates the target bandwidth value, k indicates the valid payload, f indicates the first frequency, and N indicates the first channel number; sending, by the bus controller, a bandwidth negotiation request carrying the first frequency and the first channel number to a bus controller of a first peer end; receiving, by the bus controller, a negotiation result sent by the bus controller of the first peer end; in response to the bus controller determining, according to the negotiation result, that the bus controller of the first peer end is capable of controlling the physical component of the first peer end to receive data via the channel corresponding to the first channel number according to the first frequency, controlling, by the bus controller, the physical component to transmit data via the channel corresponding to the first channel number according to the first frequency; and in response to the bus controller determining, according to the negotiation result, that the bus controller of the first peer end is not capable of controlling the physical component of the first peer end to receive data via the channel corresponding to the first channel number according to the first frequency, controlling, by the bus controller, the physical component to transmit data continually via channels corresponding to a current first channel number according to a current operating frequency. |
