1. A data transmission method, comprising:
receiving scheduling information from a network device;
obtaining second indication information, wherein the second indication information indicates that a first transport block is for retransmission, wherein the first transport block is transmitted in an unicast transmission mode, and the first transport block is for retransmission of a transport block transmitted in a multicast transmission mode;
receiving, based on the scheduling information, the first transport block from the network device;
determining a first hybrid automatic repeat request (HARQ) process identifier of the first transport block;
determining a first HARQ process based on the first HARQ process identifier; and
allocating the first transport block to the first HARQ process.
