A resource indication method includes generating, by a network device, first control information, where the first control information is used to indicate a frequency resource occupied to transmit data in N time resource units, and N is a positive integer greater than or equal to 2; and sending, by the network device, the first control information to a terminal device. Therefore, the network device may indicate, for the scheduled N time resource units, the frequency resource occupied to transmit data in the N time resource units.
