Claim 0:
1. A data transmission method, applied to a network access device, comprising:
determining a size of a first transmission sub-block sent on an available time-domain resource of a target time slot based on a first length of the available time-domain resource, a size of an available frequency-domain resource, and a modulation mode and a code rate used in physical layer resource mapping, when a target length of a time-domain resource required by a target transmission block is greater than the first length of the available time-domain resource of the target time slot;
dividing the target transmission block into the first transmission sub-block and a second transmission sub-block based on the size of the first transmission sub-block and a size of the target transmission block, wherein a second length of a time-domain resource required by the second transmission sub-block is equal to a difference between the target length and the first length;
determining a first time-domain resource of the second length for sending the second transmission sub-block in the next time slot after the target time slot based on the second length of the time-domain resource required by the second transmission sub-block; and
sending a first resource allocation message to a terminal, wherein the first resource allocation message comprises the size of the first transmission sub-block, first indication information representing the available time-domain resource of the target time slot configured to send the first transmission sub-block, and second indication information of the first time-domain resource configured to send the second transmission sub-block in the next time slot after the target time slot.
