    Abstract: The present invention discloses an uplink data transmission method and device configured to shorten RTT in a transmission condition having a short time slot, thus reducing a user-plane latency and improving the system performance. An embodiment of the present invention provides an uplink data transmission method. The method comprises: determining, by the network side, a time slot size for data transmission, and sending, according to the time slot size, uplink scheduling signaling to a user equipment (UE); and receiving, by the network side and according to a predetermined scheduled timing, uplink data sent by the UE, wherein the time slot is a time unit having a duration smaller than 1 ms, and the predetermined scheduled timing is that when the network side employs a time slot n to send the uplink scheduling signaling, the network side receives the uplink data sent by the UE in a time slot (n+1), with 1∈L, n and 1 both being integers greater than or equal to zero, and L denoting the set of selectable values of 1.

    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: A transmission method, a terminal and a base station are provided, thereby solving the problem that there is no specific method in the 5G system for distinguishing whether one DCI triggers the transmission of data and control information at the same time or triggers the transmission of control information only. The transmission includes receiving DCI, wherein the DCI comprises indication information of N bits, the indication information of N bits is used to indicate whether the DCI triggers transmission of data, and N is an integer greater than or equal to 1; and performing transmission based on the indication information in the DCI.

    Abstract: Disclosed in the present application are a method and device for transmitting feedback information, used to define new feedback timing for downlink data using a dynamic and variable TTI length during transmission, so as to ensure that ACK/NACK feedback information of downlink data is fed back on an earliest uplink transmission resource meeting a processing delay requirement, thereby reducing system delay. The method for transmitting feedback information provided in the present application comprises: receiving downlink transmission; and determining, at least according to a TTI length and/or a second TTI length of the downlink transmission, an uplink time-domain resource position for ACK/NACK feedback information transmission for the downlink transmission, and sending, on the uplink time-domain resource position, the ACK/NACK feedback information for the downlink transmission, wherein the second TTI length is configured by configuration signaling or is a pre-arranged TTI length used for determining the uplink time-domain resource position of ACK/NACK feedback information transmission.
