Claim 0:
1. An information transmission method, comprising:
retransmitting a physical downlink shared channel (PDSCH) traffic with a length of a second transmission time interval (TTI) after an initial transmission of the PDSCH traffic with a length of a first TTI fails, wherein duration of the first TTI is less than duration of the second TTI;
wherein a first transmission unit is supported in the first TTI, a second transmission unit and a third transmission unit are supported in the second TTI, and a transmission unit of the second TTI corresponds to a transmission unit of the first TTI; and
wherein the transmission unit of the second TTI corresponding to the transmission unit of the first TTI comprises that: when the first TTI is a subslot-level TTI, the first transmission unit supported in the first TTI is a transport block, the second TTI is a subframe-level TTI, the second transmission unit and the third transmission unit supported in the second TTI are codeword 0 and codeword 1, respectively, the codeword 0 in the subframe-level TTI for retransmitting the PDSCH traffic corresponds to the transport block in the subslot-level TTI for the initial transmission of the PDSCH traffic in a predefined manner.
