Abstract: The present application relates to the field of communications, and disclosed are a method and device for determining an information domain value in a DCI. The method and device are used for reducing HARQ feedback overheads, and the method comprises during HARQ feedback, determining a value set indicated by a timing relationship in a fallback DCI (equivalent to a format 1_0 of a DCI) according to a value set indicated by a timing relationship in a non-fallback DCI (equivalent to a format 1-1 of a DCI), to overcome the problem of increasing a codebook caused by different value ranges indicated by the timing relationships in the fallback DCI and in the non-fallback DCI, so that the HARQ feedback overheads are effectively reduced, thus the system running load is reduced, and the system performance is effectively ensured.

Abstract: Disclosed in the invention are a transmission method, a device, a terminal, a base station and a storage medium. The method comprises: the terminal receiving a downlink transmission; and sorting ACK/NACK feedback information of the downlink transmission according to a DAI corresponding to the downlink transmission, to obtain an ACK/NACK sequence to be fed back, and sending same. The DAI performs cumulative counting on the downlink transmission, according to at least the order of a transmitting and receiving node (TRP). Provided is a transmission scheme in which ACK/NACK feedback can be performed in a case where the terminal simultaneously receives two PDSCHs in the same serving cell.

Abstract: A method for determining and configuring a resource used for transmitting downlink data, a terminal and a base station: the base station configures, for each terminal, resource collections or resource collection subgroups used for receiving downlink data, and then the base station notifies the terminal, by means of an explicit signaling, whether all of the resource collections or each resource collection of the configured resource collections are available, or whether all of resource collection subgroups or each resource collection subgroup of the resource collection subgroups are available, thus allowing the terminal to determine, according to the notification, the time-frequency resource position of a resource used to receive downlink data, so that the terminal may carry out rate matching on the determined resource.
