Abstract: A 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; and when a preset retransmission condition in the lifetime of the automatic repeat request process is satisfied, retransmitting a second packet; where the preset retransmission condition includes that at least part of the time instants within the first predetermined time interval after an incorrect-reception acknowledgement frame returned by the receiver is received is beyond the lifetime of the automatic repeat request; where retransmitting the second packet includes: extending the lifetime of the automatic repeat request process to a third predetermined time interval following the first predetermined time interval, where the third predetermined time interval is at least a time period required for retransmitting the second packet; and retransmitting the second packet after the first predetermined time interval.

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: Provided are a method and a device for sending traffic indication information. In the method, an AP sends a radio frame to multiple STAs associated with the AP, wherein the radio frame carries an indication field, and the indication field is used to indicate whether the radio frame carries traffic indication virtual bitmap information. According to the technical solution provided, in the case where the AP has no unicast cache data for any station, multiple STAs associated with the AP can know whether the AP has their respective unicast cache data to be sent.

Abstract: The present document provides a method for avoiding downlink data collision, an Access Point (AP) and a Station (STA). The method for avoiding downlink data collision includes: an AP receiving a radio frame for inquiring whether the AP has a Bufferable Unit (BU) of an STA transmitted by the STA; and after determining that there is a BU of the STA and the BU is larger than a predetermined threshold, the AP exchanging radio frames with the STA to reserve a channel, and transmitting the BU to the STA after succeeding in reserving the channel. The method can guarantee the fairness among various STAs and the reasonable utilization of channel resources, thus avoiding the collision; furthermore, the channel reservation frame transmitted by the AP can reserve a longer period of time, i.e. a plurality of BUs can be transmitted to the STA at a time, thus saving the link overhead.
