Abstract: A method including: When downlink control information includes a first field, the first field includes (N+2) bits. A quantity L of TBs is determined based on the first field. When L is greater than 1, the L TBs can include both a newly transmitted TB and a retransmitted TB. In j consecutive bits in the first field, a bit state of only one bit is 1, bit states of j−1 bits are all 0, and j=N+1−L. k=0, a bit state of a bj bit in the first field is 1, and L consecutive bits in the first field, carry NDI of the L TBs; or k=L+1, a bit state of a bL bit in the first field is 1, and L consecutive bits in the first field, carry NDI information of the L TBs.

Abstract: This application describes a data transmission method, a communications apparatus, a storage medium, and a program product. In one example implementation, a network device is no longer confined to allocating an RB only in a narrowband to BL/CE UE, but can also allocate an RB outside the narrowband to the BL/CE UE, so that resources are flexibly allocated by the network device to the BL/CE UE. In this way, when the network device allocates resources to the BL/CE UE in one subframe, a quantity of fragmented resources that cannot be used by conventional UE in remaining resources in a system bandwidth can be reduced, so that the remaining resources can be used by other conventional UE to a maximum extent, thereby improving system resource utilization.
