Abstract: Disclosed are a method and device for transmitting uplink control information (UCI). By applying technical solutions of embodiments of the present invention, implemented is a method for simultaneously transmitting an ACK/NACK and cycle CSI on a channel resource corresponding to a current subframe: dynamically determining, on the basis of a threshold number of bits simultaneously transmitted with the UCI in the current subframe, also of the maximum number of feedback bits and of the minimum number of feedback bits of the ACK/NACK in the current subframe, ACK/NACK bits and CSI bits simultaneously transmitted in the current frame, thus ensuring that the sum of the bits simultaneously transmitted does not exceed the threshold number of bits simultaneously transmitted with the UCI in the current subframe, preventing as much as possible ACK/NACK merging and CSI discarding, and protecting to the maximum extent the accuracy and completeness of UCI transmission.

Abstract: The embodiments of the present application relate to a method for performing hybrid automatic repeat request feedback, and a terminal, for solving the problem existing in the prior art that there is no clear solution regarding how to perform feedback on HARQ-ACK of an SPS PDSCH. In the embodiments of the present application, the terminal adds or removes HARQ-ACK of an SPS PDSCH in an HARQ-ACK codebook transmitted over a PUCCH or a PUSCH, and transmits a processed HARQ-ACK codebook. Since the terminal can add or remove the HARQ-ACK of the SPS PDSCH in the HARQ-ACK codebook transmitted over the PUCCH or the PUSCH, a solution to perform feedback on the HARQ-ACK of the SPS PDSCH is given, improving system performance.

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.
