    Abstract: Provided are a method, a device, and a system for determining transmission information. The method includes determining, by a first node, transmission information according to a predetermined information combination in downlink control information, DCI, transmitted by a second node. The transmission information includes a modulation coding scheme, joint information of a modulation coding scheme and a sub-carrier position, or sub-carrier position information. The predetermined information combination includes one of the following: a combination of a modulation-coding-scheme indicator domain IMCS and a number of allocated sub-carriers, and a combination of a resource-unit, RU, number indicator domain and a number of allocated sub-carriers.

    Abstract: A transmitting method for HARQ information comprising: a first node detecting N transmission blocks received from a second node and generating M bits of HARQ information according to the detection result; the M bits of HARQ information being used to indicate the receiving status of the N transmission blocks; there being M2 bits among the M bits, for indicating the positions of k erroneous transmission blocks in the N transmission blocks, M2≤M; the length type of M2 including a first length type or a second length type; the first length type indicating that the value for M2 is predefined, and the second length type indicating that the value for M2 is determined based on k; and the first node transmitting the HARQ information to the second node. The above technical solution does not require strong correlation for the channel, and can conserve transmission resources and improve system throughput while reducing the HARQ information feedback overhead.
