Abstract: Disclosed in the present application are a data transmission method and a device, comprising: dividing a time unit into DL areas, a time unit including at least two DL areas; notifying a terminal of the divided DL areas by means of configuration signaling. The terminal receiving the configuration signaling; according to said configuration signaling, determining DL areas into which a time unit is divided. Using the present application, defining at least two DL detection areas in a time unit, a terminal detects a downlink transmission in each detection area, and, when one is detected, performs ACK/NACK feedback in an uplink area corresponding to said downlink area. In the present invention, each downlink area has a defined feedback and scheduling relationship, respectively, by means of dividing a time unit into multiple downlink areas, thereby increasing scheduling flexibility and system resource utilization.

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.
