An information processing method, comprising: receiving, by a terminal device, downlink control information from a network device, wherein the downlink control information is capable of being used to schedule a maximum of N transport blocks, TBs, and N is a positive integer; wherein when the terminal device determines that the downlink control information comprises a first field, the first field comprises (N + 2) bits, namely, b 0, b 1,..., and b N + 1; determining, by the terminal device based on the first field, a quantity L of TBs scheduled by using the downlink control information, wherein L is a positive integer, and 1 ≤ L ≤ N; when L is greater than 1, the L TBs scheduled by using the downlink control information can comprise both a newly transmitted TB and a retransmitted TB; and in j consecutive bits, namely, b k, b k + 1,..., and b k + j - 1 in the first field, a bit state of only one bit is 1, bit states of other j - 1 bits are all 0, j is a positive integer, j = N + 1 - L, k is a predefined integer, and k = 0 or k = L + 1, wherein k = 0, a bit state of the b j bit in the first field is 1, and L consecutive bits, namely, b j + 1, b j + 2,..., and b N + 1 in the first field, carry new data indicator, NDI, information of the L TBs scheduled by using the downlink control information; or k = L + 1, a bit state of the b L bit in the first field is 1, and L consecutive bits, namely, b 0, b 1,..., and b L - 1 in the first field, carry NDI information of the L TBs scheduled by using the downlink control information; determining, by the terminal device, a HARQ process number of each of the L TBs; and sending or receiving, by the terminal device, the L TBs based on the determined HARQ process number of each of the L TBs and the NDI information of each of the L TBs; wherein L, a HARQ process number of a first TB in the L TBs, and the NDI information of each of the L TBs are determined according to a correspondence between a bit state of the first field, and a quantity of TBs, the HARQ process number of the first TB, and the NDI information of the L TBs, and the first TB is one of the L TBs. receiving, by a terminal device, downlink control information from a network device, wherein the downlink control information is capable of being used to schedule a maximum of N transport blocks, TBs, and N is a positive integer; wherein when the terminal device determines that the downlink control information comprises a first field, the first field comprises (N + 2) bits, namely, b 0, b 1,..., and b N + 1; determining, by the terminal device based on the first field, a quantity L of TBs scheduled by using the downlink control information, wherein L is a positive integer, and 1 ≤ L ≤ N; when L is greater than 1, the L TBs scheduled by using the downlink control information can comprise both a newly transmitted TB and a retransmitted TB; and in j consecutive bits, namely, b k, b k + 1,..., and b k + j - 1 in the first field, a bit state of only one bit is 1, bit states of other j - 1 bits are all 0, j is a positive integer, j = N + 1 - L, k is a predefined integer, and k = 0 or k = L + 1, wherein k = 0, a bit state of the b j bit in the first field is 1, and L consecutive bits, namely, b j + 1, b j + 2,..., and b N + 1 in the first field, carry new data indicator, NDI, information of the L TBs scheduled by using the downlink control information; or k = L + 1, a bit state of the b L bit in the first field is 1, and L consecutive bits, namely, b 0, b 1,..., and b L - 1 in the first field, carry NDI information of the L TBs scheduled by using the downlink control information; determining, by the terminal device, a HARQ process number of each of the L TBs; and sending or receiving, by the terminal device, the L TBs based on the determined HARQ process number of each of the L TBs and the NDI information of each of the L TBs; wherein L, a HARQ process number of a first TB in the L TBs, and the NDI information of each of the L TBs are determined according to a correspondence between a bit state of the first field, and a quantity of TBs, the HARQ process number of the first TB, and the NDI information of the L TBs, and the first TB is one of the L TBs.
