Abstract
Provided are a data transmission method and a terminal. In the method, a terminal receives Downlink Control Information (DCI) sent by a network side device; the terminal detects downlink data sent by the network side device based on the DCI; and the terminal determines, according to an index of a time element for transmitting downlink information or according to a time element offset between the time element for transmitting the downlink information and a time element for transmitting feedback information corresponding to the downlink data, a resource index of a target uplink control channel resource for transmitting the feedback information, the downlink information including at least one of the DCI and the downlink data.

- detecting, by the terminal, downlink data sent by the network side device based on the DCI;
- and
- determining, by the terminal according to a time element offset between a time element for transmitting the downlink control information and a time element for transmitting feedback information corresponding to the downlink data, a resource index of a target uplink control channel resource for transmitting the feedback information;
- wherein the downlink control information carries the time element offset between the time element for transmitting the downlink control information and the time element for transmitting the feedback information;
- wherein determining, by the terminal according to the time element offset between the time element for transmitting the downlink control information and the time element for transmitting the feedback information corresponding to the downlink data, the resource index of the target uplink control channel resource for transmitting the feedback information comprises:
- determining, by the terminal, the resource index according to one of the following formulas:
