Abstract

Embodiments of the present disclosure provide a data transmission method. The method includes: sending, by a network device, first indication information, where the first indication information includes N bits, the N bits are corresponding to M time units, the M time units are corresponding to at least one time length, a value of each bit is used to indicate whether a corresponding time unit is used to transmit data of a terminal device, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1; and sending, by the network device, downlink data in a time unit that is used to transmit the data of the terminal device, where the time unit is indicated by the N bits. Therefore, a unified time domain resource indication manner can be used in different scenarios to reduce complexity of a signaling design.
