Abstract
A HARQ feedback indication method includes: configuring to control information a timing relationship between a time domain unit of downlink data and a time domain unit for an uplink HARQ feedback of the downlink data; and sending to a terminal the downlink data and the control information configured with timing information.
Claims12
A hybrid automatic repeat request (HARQ) feedback indication method, applied to a base station, the method comprising:
- sending signaling for triggering dynamic HARQ feedback to a terminal;
- configuring, in control information, a timing relationship between a first time domain unit where downlink data is configured and a second time domain unit for an uplink HARQ feedback of the downlink data, wherein the control information comprises downlink control information (DCI), the signaling for triggering dynamic HARQ feedback comprises RRC signaling or media access control (MAC) control element (CE);
- and
- sending the downlink data and the control information configured with the timing relationship to the terminal;
- wherein the timing relationship is configured in an information domain of the DCI, the information domain is configured at a fixed location or a configurable location in the DCI, and a length of the information domain is fixed or configurable.

A hybrid automatic repeat request (HARQ) feedback method, applied to a terminal, the method comprising:
- receiving signaling for triggering dynamic HARQ feedback sent by a base station;
- receiving downlink data sent by the base station and control information configured with a timing relationship between a first time domain unit where the downlink data is configured and a second time domain unit for an uplink HARQ feedback of the downlink data sent by the base station, wherein the control information comprises downlink control information (DCI), the signaling for triggering dynamic HARQ feedback comprises RRC signaling or media access control (MAC) control element (CE);
- parsing the timing relationship from the control information;
- and
- sending, according to the timing relationship and the first time domain unit where the downlink data is configured, uplink HARQ feedback information of the downlink data to the base station in a corresponding time domain unit;
- wherein the timing relationship is configured in an information domain of the DCI, the information domain is configured at a fixed location or a configurable location in the DCI, and a length of the information domain is fixed or configurable.
