Abstract: The present disclosure relates to the mobile communications field, and in particular, to a transmission resource determining technology in a wireless communications system. In a data transmission method, a network device determines a transmission resource used for data transmission, and performs data transmission with a terminal device on the determined transmission resource. A time domain resource occupied by the transmission resource in a time domain is one of N types of time domain resources, and a time length of any type of time domain resource in the N types of time domain resources is less than 1 ms. According to this method, a data transmission latency can be effectively reduced, thereby meeting a requirement for a low-latency service.

Abstract: Embodiments of the present disclosure provide a data communication method, a terminal device, and a network device. In the solution, a terminal device receives first indication information in a first time period; and the terminal device transmits first information in a second time period, where a duration of the first time period is a first time unit, a duration of the second time period is a second time unit, and a duration of the second time unit is greater than a duration of the first time unit. In this way, although the terminal device receives the first indication information in a first time unit N, the terminal device transmits the first information in a second time unit M whose duration is greater than that of the first time unit.

Abstract: Example control information transmission methods and apparatus are described. One example control information transmission method includes that a terminal device determines a transmission resource based on a receiving status of downlink data and a scheduling request transmission status. The transmission resource is one of N first resources or one of M second resources. The N first resources are corresponding to N receiving statuses of the downlink data, and the M second resources are used to transmit a scheduling request. N is a positive integer greater than 1, and M is a positive integer. The terminal device sends uplink control information on the transmission resource.
