Abstract: The present disclosure relates to data scheduling methods, apparatus, and systems. In one example method, a network device sends, to a terminal device, downlink control information (DCI) used to schedule N transport blocks (TBs). After determining that a downlink channel that carries first M TBs in the N TBs is transmitted in consecutive first downlink time units, the network device sends the downlink channel to the terminal device. The terminal device receives the downlink channel. After determining that ACKs/NACKs corresponding to the M TBs are transmitted in consecutive first uplink time units, the terminal device sends the ACKs/NACKs corresponding to the M TBs to the network device. N is a positive integer greater than 1, and M is a positive integer greater than 1 and less than or equal to N.
