Method for realizing sending of hybrid automatic repeat request information, and data receiving end

A data receiving end for sending of Hybrid Automatic Repeat reQuest (HARQ) information, comprising:

• a determination unit and a feedback sending unit, wherein
• the determination unit is configured to determine a number of bits of HARQ according to a number of scheduling resources and a feedback number of expected maximum feedback Acknowledgements (ACKs);
• and
• the feedback sending unit is configured to determine HARQ information according to detection results for received transport blocks, and send the HARQ information to a data sending end by using the determined number of bits of HARQ;
• wherein the feedback number is M, and the number of scheduling resources is N;
• and the N is a positive integer greater than or equal to 3, and the M is a positive integer less than the N.
