1. A data transmission method, wherein the method is applicable to a first terminal device, and comprises:
receiving downlink control information (DCI) from an access network device, wherein the DCI comprises information to schedule a paging message and to schedule downlink data, the DCI further comprising at least one bit indicating that there is first downlink data to be sent to the first terminal device;
receiving the paging message from the access network device, wherein the paging message comprises a paging record list and first indication information, and the first indication information indicates that there is the first downlink data corresponding to the first terminal device to be sent, the first indication information comprising:
a list of indication information corresponding to the paging record list, wherein a value of True in the list of indication information corresponds to an identifier of a terminal device in the paging record list and indicates that there is downlink data for the terminal device, or
a quantity X of identifiers of terminal devices at which the downlink data is to arrive; and
in response to determining, based on the DCI, the paging record list, and the first indication information, that there is the first downlink data corresponding to the first terminal device, receiving the first downlink data from the access network device.
