1. An ACK/NACK feedback method, comprising:

  • a terminal receives a first physical downlink control channel, wherein Downlink Control Information (DCI) of the first physical downlink control channel carries a first indication domain, and the first indication domain is used for determining the time domain position of ACK/NACK feedback information;

    the time domain position is any one of the following;

    subframe number and/or symbol number and/or transmission time interval, TTI, number and/or timeslot number and/or minislot number;

    the terminal determines the time domain position of the ACK/NACK feedback information of the first physical downlink control channel or a first physical downlink shared channel corresponding to the first physical downlink control channel according to the first indication domain, and transmits the ACK/NACK feedback information at the time domain position of the ACK/NACK feedback information;

    the terminal determines the position of a radio frame or a half frame or a subframe or a time slot or a micro time slot or a symbol where the time domain position of the ACK/NACK feedback information indicated by the first indication domain is located according to a first TTI length and/or a second TTI length, wherein the first TTI length is the TTI length of the first physical downlink control channel and/or a first physical downlink shared channel corresponding to the first physical downlink control channel, and the second TTI length is a preset or agreed TTI length used for determining the time domain position of the ACK/NACK feedback information.
