The invention provides a data transmission method and a wireless communication system. The method is applied to a wireless communication system. The system includes multiple gateway devices and multiple detection devices. The gateway device sequentially sends beacon messages to the detection device within a beacon time slot segment according to the sequence number of the gateway device. The detection device determines the time period for receiving the data message in the delivery time slot and the time period corresponding to the data upload by the detection device in the reporting time slot according to the received beacon message. The gateway device sends data according to the sequence number of the gateway device within the sending time slot. The detection device receives data in the corresponding time period. The detection device uploads data in the time period corresponding to the reporting time slot. The uplink data and downlink data are separated and time-sharingly transmitted, and no handshake is required when transmitting data, thereby reducing the power consumption of the detection device and simplifying the complexity of the protocol stack.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular, to a data transmission method and a wireless communication system. Background technique [0002] With the advent of the Internet of Things era, various wireless networking solutions of the Internet of Things are applied to various scenarios, and various wireless networking methods have developed rapidly. At present, there are many point-to-point and point-to-multipoint wireless networking methods, that is, a host and a device or multiple devices perform two-way data transmission through wireless. [0003] In some specific environments, a large number of sensor devices are deployed in a certain area, and the data of the regional sensor devices needs to be reported regularly and in a large area, but the downlink data is very little. In practical applications, a large number of wireless hosts will be arranged for such situations. For a system with so many wireless devi...
