Abstract
A method and apparatus for feeding back a hybrid automatic repeat request (HARQ) are provided. A user equipment (UE) buffers, in response to detecting that a signal of other equipment is being transmitted at a current time-frequency resource location, HARQ feedback information to be fed back. The UE may further send the HARQ feedback information at a preset time-frequency resource location of at least part of a plurality of preset frequency bands according to priorities of the plurality of preset frequency bands.
Claims20
A method of feeding back a hybrid automatic repeat request (HARQ), applied to user equipment (UE), and comprising:
- buffering, in response to detecting that a signal of an equipment is transmitted at a current time-frequency resource location, HARQ feedback information to be fed back;
- and
- sending the HARQ feedback information at a preset time-frequency resource location of at least part of a plurality of preset frequency bands according to priorities of the plurality of preset frequency bands.
A method of determining success or failure of data transmission, applied to a base station, and comprising:
- receiving hybrid automatic repeat request (HARQ) feedback information from user equipment (UE) at a preset time-frequency resource location in a descending order of priorities corresponding to a plurality of preset frequency bands;
- and
- determining success or failure of data transmission corresponding to the HARQ feedback information according to the received HARQ feedback information.
A device, comprising:
- one or more processors, and
- a non-transitory computer-readable storage medium for storing instructions executable by the one or more processors,
- wherein the one or more processors are configured to:
- buffer, in response to detecting that a signal of an equipment is transmitted at a current time-frequency resource location, hybrid automatic repeat request (HARQ) feedback information to be fed back;
- and
- send the HARQ feedback information at a preset time-frequency resource location of at least part of a plurality of preset frequency bands according to priorities of the plurality of preset frequency bands.
