Abstract: Provided are a transmission method, apparatus and system and a computer-readable storage medium. The transmission method includes creating an automatic repeat request process for a first packet; setting a lifetime for the automatic repeat request process; and sending the first packet. The lifetime is set for the automatic repeat request process so that the automatic repeat request process can be removed in time. In this manner, in the case where a limited number of automatic repeat request processes are simultaneously supported, a new automatic repeat request process can be created for a newly transmitted packet in time, and thus the transmission efficiency is improved.

Abstract: A method for processing a network allocation vector (NAV) includes: terminating the receiving of a first radio frame when it is determined that a target receiving station of the first radio frame being received is not a first station; and updating an NAV of the first station or maintaining the NAV of the first station unchanged according to a remaining duration of the first radio frame and a first transmission opportunity duration carried in the first radio frame, where the remaining duration of the first radio frame is the transmission time used for transmitting the remaining part of the first radio frame after the receiving of the first radio frame is terminated. The technical solution solves the problem in the related art of collisions with hidden stations caused by an inaccurate NAV update in the existing art, thereby ensuring the accuracy of an NAV update and the fairness of transmission and channel contention, and reducing collisions among hidden stations.
