Claim 6:
7. 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;
wherein in response to a plurality of pieces of received HARQ feedback information, determining success or failure of the data transmission corresponding to the HARQ feedback information according to the received HARQ feedback information comprises:
obtaining a priority of a preset frequency band corresponding to at least one of the plurality of pieces of received HARQ feedback information, determining a highest priority from the obtained priorities, and determining success or failure of the data transmission corresponding to the HARQ feedback information according to a piece of HARQ feedback information corresponding to the determined highest priority; or
voting on bit values of the plurality of pieces of received HARQ feedback information, and determining success or failure of the data transmission corresponding to the HARQ feedback information according to a bit value with more votes; or
obtaining a priority of a preset frequency band corresponding to at least one of the plurality of pieces of received HARQ feedback information, determining a preset number of top-ranked priorities from the obtained priorities, voting on bit values of a plurality of pieces of HARQ feedback information corresponding to the preset number of top-ranked priorities, and determining success or failure of the data transmission corresponding to the HARQ feedback information according to a bit value with more votes.
