1. A data transmission method, comprising: receiving, by a first communications device, flag information from a second communications device; and
in response to the flag information indicating that one piece of control information is able to be used for scheduling of a plurality of transport blocks:
obtaining, by the first communications device, transport block allocation information from the second communications device, wherein the transport block allocation information indicates a number N of transport blocks scheduled by the one piece of control information and a bit state corresponding to each transport block of the number N of transport blocks; and
performing one or more of:
(i) sending, by the first communications device, data to the second communications device based on the flag information and the bit state corresponding to each transport block of the number N of transport blocks and by using at least one transport block indicated by the control information, wherein N is a positive integer, or
(ii) receiving, based on the flag information and the bit state corresponding to each transport block of the number N of transport blocks and by using at least one transport block indicated by the one piece of control information, data from the second communications device,
wherein the at least one transport block belongs to the N transport blocks; and in response to the flag information indicating that one piece of control information is able to be used for scheduling of only one transport block:
obtaining, by the first communications device, hybrid automatic repeat request (HARQ) process number information from the second communications device, wherein the HARQ process number information indicates an HARQ process number corresponding to the only one transport block scheduled by using the one piece of control information; and
performing one or more of:
(i) sending, by the first communications device, data to the second communications device based on the flag information and the HARQ process number corresponding to the only one transport block, or
(ii) receiving, based on the flag information and the HARQ process number corresponding to the only one transport block, data from the second communications device.
