Embodiments of this application relate to the field of chip technologies, and provide a high-speed serial interface and a data transmission method, to reduce power consumption of a physical layer circuit of a high-speed serial interface when no service data is being sent. The high-speed serial interface includes a physical layer circuit at a transmit end, a monitor, a clock gating circuit, a control bitstream generation circuit, and a random bitstream generation circuit, and further includes: The monitor is configured to: when no service data is being sent, indicate the clock gating circuit to stop sending a clock signal to partial modules in the physical layer circuit at the transmit end. The control bitstream generation circuit sends a first control bitstream through a serializer/deserializer, to indicate that the transmit end has turned off partial modules in the physical layer circuit at the transmit end, or indicate that the transmit end is to turn off partial modules in the physical layer circuit at the transmit end, or indicate a receive end to turn off partial modules in a physical layer circuit at the receive end. The random bitstream generation circuit sends a random bitstream. Embodiments of this application are used in a process of reducing power consumption of a physical layer circuit.

A transmission method for broadcast multicast services is disclosed. The method includes: in a cell that adopts frequency reuse, determining a frequency resource occupied by broadcast multicast service data transmitted by a broadcast multicast cell based on a multi-cell transmission mode; selecting a corresponding frequency resource from a frequency band that is occupied by a unicast cell adjacent to the broadcast multicast cell and has the same frequency resource as the determined frequency resource; transmitting, by the unicast cell based on the selected frequency resource and the broadcast multicast cell based on the determined frequency resource, broadcast multicast service data synchronously. The present invention also discloses a transmission system for broadcast multicast services. The present invention can improve the performance of receiving broadcast multicast services by users in a transition zone between the unicast cell and the broadcast multicast cell.

A communication system with serial ports for automatically identifying device types and communication protocols and method thereof are described. The communication system and method are capable of automatically identifying the device types and communication protocols of interface devices with different serial device numbers which are disposed in the serial port architecture. Furthermore, the drivers are capable of performing a serial communication based on the serial port architecture for matching the device types and communication protocols correspondingly, thereby reducing the development and manufacturing costs of communication system. Moreover, the user of an application program module only needs to provide the device numbers and data control information without the cooperation of hardware circuits and manufacturing technique of the interface devices to complete the automatic control and monitoring tasks of the interface devices to increase the utilization convenience.
