Method for transmitting hybrid automatic repeat request feedback, and communication device

A method for transmitting a hybrid automatic repeat request (HARQ) feedback, performed by a second communication end, comprising:

• receiving a reception feedback frame sent by a first communication end;
• and
• determining a reception status of a block based on a reception feedback of the block in a data frame comprised in the reception feedback frame, wherein the data frame is transmitted in blocks;
• said determining a reception status of a block based on a reception feedback of the block in a data frame comprised in the reception feedback frame comprising:
• determining a reception status of at least one first-class data block of a media access control service data unit (MSDU) divided into multiple first-class data blocks based on a reception feedback of the at least one first-class data block comprised in the reception feedback frame;
• determining a reception status of at least one second-class data block in at least one A-MSDU sub-frame of an aggregation media access control service data unit (A-MSDU) comprising a plurality of A-MSDU sub-frames each divided into multiple second-class data blocks based on a reception feedback of the at least one second-class data block comprised in the reception feedback frame.

A communication device, comprising:

• a processor, a memory storing an executable program executed by the processor;
• wherein when the processor executes the executable program, the processor performs steps of a method for transmitting a hybrid automatic repeat request (HARQ) feedback, comprising:
• generating a reception feedback frame comprising a reception feedback of a block in a data frame based on a reception status of the block of the data frame transmitted in blocks;
• and
• sending the reception feedback frame;
• said generating a reception feedback frame comprising a reception feedback of a block in a data frame based on a reception status of the block of the data frame transmitted in blocks comprising:
• generating the reception feedback frame comprising a reception feedback of at least one first-class data block of a media access control service data unit (MSDU) based on a reception status of the at least one first-class data block, wherein the data frame is the MSDU divided into multiple first-class data blocks;
• generating the reception feedback frame comprising a reception feedback of at least one second-class data block in at least one aggregation media access control service data unit (A-MSDU) sub-frame of an A-MSDU based on a reception status of the at least one second-class data block, wherein the data frame is the A-MSDU comprising a plurality of A-MSDU sub-frames each divided into multiple second-class data blocks.
