Problems solved by technology

[0003] After the network device detects the signal sent by the terminal device, it needs to send feedback information to the terminal device, so that the terminal device can perform subsequent processing according to the feedback information. When there are many terminal devices sending data in one access slot, the feedback information sent by the network device There are also many, and the terminal device needs to determine its own feedback message from a large amount of feedback information, which leads to an increase in the complexity of the terminal device receiving feedback information

Embodiment Construction

[0050] The technical solution in this application will be described below in conjunction with the drawings.

[0051] figure 1 A communication system 100 applicable to the present application is shown. The communication system 100 includes a network device 110 and a terminal device 120. The network device 110 and the terminal device 120 communicate through a wireless network. When the terminal device 120 sends data, the wireless communication module can encode the information for transmission. Specifically, The wireless communication module may acquire a certain number of data bits to be sent to the network device 110 through the channel, and these data bits are, for example, data bits generated by the processing module, received from other devices, or stored in the storage module. These data bits may be contained in one or more transmission blocks (also referred to as information blocks), and the transmission blocks may be segmented to generate multiple code blocks.

Abstract

The invention provides a data transmission method and device. The method comprises that first terminal equipment receives a feedback information set which includes at least one piece of feedback information from network equipment; the first terminal equipment determines the first feedback information in the feedback information set according to position information; and the position information indicates a position of the first feedback information in the feedback information set and is determined by the first terminal equipment according to position of a first resource in a candidate resourceset, the first terminal equipment sends first data to the network equipment via the first resources, and the first feedback information is feedback information of the first data. Via the data transmission method and device, the first terminal equipment is easier to receive the feedback information.

Description

Technical field [0001] This application relates to the field of communications, and in particular to methods and devices for data transmission in the field of wireless communications. Background technique [0002] The grant-free scheme is a communication method that can send data to the network device without the terminal device moving to the connected state. When the terminal device needs to send data, it directly sends the data and the identification of the terminal device to the network device. After correctly detecting the signal sent by the terminal device, obtain the data and the identification of the terminal device. [0003] The network device needs to send feedback information to the terminal device after detecting the signal sent by the terminal device, so that the terminal device can perform subsequent processing based on the feedback information. When there are many terminal devices sending data in an access time slot, the feedback information sent by the network device...
