Data retransmission method and access point device

An access point device, serving as a first access point device, applied to a wireless fidelity system, the access point device comprising:

• a processor, wherein the processor is configured to invoke and execute a computer program from a memory to perform:
• transmitting first request information to a second access point device based on the first access point device failing to transmit a first data frame to a station device, the first request information requesting the second access point device to retransmit the first data frame, and the first access point device and the second access point device belonging to one operation set, wherein the operation set comprises access point devices participating in cooperation transmission with the first access point device, wherein the second access point device is used to retransmit the first data frame to the station device in response to the first request information;
• receiving first response information transmitted by the second access point device, the first response information instructing the first access point device to continue transmitting data frames;
• transmitting a second data frame to the station device;
• and
• determining, based on a count value of a first counter reaching a first threshold, whether to exchange identity information of the first access point device and the second access point device in the operation set;
• wherein the first counter is configured to record a number of retransmissions by the second access point device, and the count value of the first counter is decremented by 1 based on a number of consecutive successful transmissions by the first access point device reaching a predetermined value;
• and
• wherein in the operation set, an identity of the first access point is initial transmission of data frame, and an identity of the second access point is retransmission of data frame.

A non-transitory computer-readable storage medium, applied to a wireless fidelity system, wherein the non-transitory computer-readable storage medium stores a computer program that causes a computer to:

• transmit first request information to a second access point device based on a first access point device failing to transmit a first data frame to a station device, the first request information requesting the second access point device to retransmit the first data frame, and the first access point device and the second access point device belonging to one operation set, wherein the operation set comprises access point devices participating in cooperation transmission with the first access point device, wherein the second access point device is used to retransmit the first data frame to the station device in response to the first request information;
• receive first response information transmitted by the second access point device, the first response information instructing the first access point device to continue transmitting data frames;
• transmit a second data frame to the station device;
• and
• determine, based on a count value of a first counter reaching a first threshold, whether to exchange identity information of the first access point device and the second access point device in the operation set;
• wherein the first counter is configured to record a number of retransmissions by the second access point device, and the count value of the first counter is decremented by 1 based on a number of consecutive successful transmissions by the first access point device reaching a predetermined value;
• and
• wherein in the operation set, an identity of the first access point is initial transmission of data frame, and an identity of the second access point is retransmission of data frame.
