In this embodiment, if the number of transmission subchannels included in the system parameter information is 3, the current service information is transmitted through the three transmission subchannels. In the signal frame construction method of the present invention, one service information can be transmitted on multiple transmission sub-channels at the same time, which is specifically determined according to actual requirements. However, one transmission sub-channel cannot correspond to multiple services, so as to avoid confusion when data is transmitted. In this embodiment, the number of the transmission sub-channels is greater than or equal to the current number of service information. For example, if the number of current service information is 5, the number of transmission sub-channels must be greater than or equal to 5. In an embodiment, the transmission subchannel carries the encoded and modulated data signal of the payload data corresponding to each service information. Each transmission subchannel and the system parameter information channel can be independently encoded and modulated.

The division of the transmission time of the sub-channels corresponding to the service information may be divided according to the type of the service according to the information amount corresponding to the service information. For example, when transmitting multiple service information, one of the service information has low requirements on real-time performance (relative to other simultaneously transmitted service information), and the transmission time of the corresponding transmission sub-channel can also be arranged in other service information. After the transmission time of the transmission subchannel.

For example, if a service information A is required to be transmitted at 7:00 and 19:00 every day, the transmission sub-channel transmission time included in the system parameter information corresponding to the service information A is set to 7:00 and 19:00 every day, and then The system parameter information corresponding to the service information A identifies the identity identifier of the service information A according to the system parameter information, and transmits the service information according to the set transmission subchannel transmission time and the corresponding number of transmission subchannels. Referring to FIG. 5, FIG. 5 is a schematic diagram of a scenario in which a specific service is transmitted at a fixed time.

In this embodiment, the number of transmission subchannels and the transmission time of each transmission subchannel are all set according to system parameter information corresponding to the current service information, and the system parameter information is automatically generated by human or software according to the service type. For example, at present, the number of transmission sub-channels corresponding to one service information is three, and the transmission time of each transmission sub-channel is a, b, and c, respectively, and the length of the signal frame corresponding to the current service information is a+b+c.

In this embodiment, when the service transmission is performed, the number of the transmission sub-channels corresponding to the current service information and the transmission time of each transmission sub-channel are flexibly configured according to the system parameter information corresponding to the current service, thereby determining the information frame corresponding to the current service information. length.
