A wireless communication method, a network device, user equipment, and a system are provided. The method includes: generating, by a network device, control information, where the control information includes first indication information used to indicate a time domain resource for first transmission between user equipment and the network device, and duration of occupying a resource by one transmission of the first transmission is less than 1 millisecond; and sending, by the network device, the control information to the user equipment. The user equipment may obtain, according to the control information, the time domain resource for communicating with the network device by using the first transmission, and communicate with the network device on the obtained time domain resource. Therefore, a transmission time delay can be shortened, and user experience and radio network performance can be greatly improved.
