    Abstract: Disclosed in the present application are an uplink control channel transmission method, a terminal, a base station and a device, for solving the problem, in the prior art, that no relevant solution addresses how to perform long NR-PUCCH transmission in multiple slots. The method applied to a terminal comprises: determining a total transmission length T of an uplink control channel (PUCCH) to be transmitted in P slots; determining the transmission structure of the PUCCH on the basis of T; and transmitting the PUCCH in the P slots according to the transmission structure. The present invention defines the transmission structure for long PUCCH transmission in multiple slots, realizing the normal transmission of the long PUCCH in multiple slots.

    Abstract: Disclosed are a method and apparatus for transmitting and detecting downlink control information. The method involves determining a state of resource allocation in a downlink transmission time period, the resource allocation corresponds to allocation of at least one downlink transmission resource region; and transmitting downlink control information on a preset resource in the at least one downlink transmission resource region, the downlink control information being used for scheduling at least one terminal to perform data transmission in the downlink transmission resource region. The method also involves detecting the downlink control information on the preset resource in the downlink transmission time period; determining, according to the detected downlink control information, a data transmission region indicated by the downlink control information; and detecting follow-up downlink control information according to the data transmission region. By using the present invention, downlink control information can be transmitted at a fixed position in each downlink transmission time period, and multiple transmission time intervals of different lengths are supported, so that rich service types in the future can be better supported.

    Abstract: The present invention discloses a transmission method and apparatus for feedback information of uplink transmission. The method comprises: a terminal transmitting a physical uplink shared channel (PUSCH) in a special sub-frame m, where m is an integer; the terminal detecting, subsequent to the special frame m, in a sub-frame comprising downlink transmission resources or in a sub-frame m+k, a downlink control channel using an uplink/downlink control information (DCI) format, where k is a positive integer; and the terminal determining, according to the downlink control channel, whether to again transmit the PUSCH transmitted in the special sub-frame m. accordingly, the present invention provides a transmission solution that transmits PUSCH feedback information in a special sub frame, ensuring that the PUSCH transmitted in the special sub frame can normally obtain ACK/NACK feedback information.
