1. A method for transmitting a data packet between a station (STA) and an access point (AP), the method comprising:
determining a capability information value supported by a data transmission end, wherein the capability information value comprises a maximum amount of data supporting hybrid automatic repeat request (HARQ) feedback; and
in response to determining that the data packet is not received correctly:
determining a maximum number of retransmissions of the data packet according to a set network transmission quality and a maximum amount of data in the capability information value, wherein under the set network transmission quality, the maximum number of the retransmissions of the data packet is inversely proportional to the maximum amount of data in the capability information value, and
retransmitting the data packet when a number of retransmissions of the data packet is less than or equal to the maximum number of the retransmissions.
