Embodiment 1

[0075] STA3 chooses to reject or discard the SU / MU VHT PPDU that is not sent to itself and does not update the local NAV settings. When STA3 needs to access the channel after the SU / MU VHT PPDU transmission ends, STA3 should end the SU / MU VHT PPDU transmission. Finally, here, STA3 can obtain the end time of PPDU through L-SIG, use EIFS as the waiting time when working under the DCF mechanism, and use EIFS-DIFS+AIFS[AC] as the waiting time when working under the EDCA mechanism The length of time to compete for the access channel; that is, xIFS in xIFS+n×aSlotTime must be EIFS or EIFS-DIFS+AIFS[AC] during competition;

[0076] Here, STA3 needs to further determine whether the local NAV is 0. When the NAV is not 0, that is, the end time of STA3's NAV is later than the end time of the waiting time, STA3 should start the access process after the end of NAV. According to EIFS or EIFS-DIFS+AIFS[AC], the time length is greater than or equal to the time of STA2 replying to the response...

Embodiment 2

[0078] STA3 chooses to reject or discard the SU / MU VHT PPDU that is not sent to itself and does not update the local NAV settings. When STA3 wants to access the channel after the end of the SU / MU VHT PPDU, STA3 must end the above SU / MU VHT PPDU After that, the local NAV can be further judged and whether to start the channel access process after one of the following conditions occurs:

[0079] After the wireless frame transmission ends, STA3 receives a frame sequence and the frame sequence correctly sets the local NAV of STA3;

[0080] After the wireless frame transmission ends, STA3 correctly decodes the L-SIG information of a PPDU physical frame header;

[0081] STA3 waits for a length of dot11VHTPSProbeDelay time that is currently specified after the wireless frame transmission ends.

Abstract

The present invention discloses a method and system for a wireless station to access a channel. The method includes: when the wireless station chooses to reject or discard the wireless frame and does not update the locally stored NAV, acquire the end time of the wireless frame transmission; When the wireless frame transmission ends and the preset condition is satisfied, channel access can be performed. In the present invention, when the wireless station may have a collision problem, the channel access can only be performed when the preset condition is satisfied after the wireless frame transmission is completed, so as to avoid the wireless station from colliding with the hidden station when the wireless frame is transmitted. Problems with transport collisions occur.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for a wireless station to access a channel. Background technique [0002] At present, in the field of wireless networks, wireless local area networks (Wireless Local Area Networks, WLAN) are developing rapidly, and the requirements for WLAN coverage are increasing day by day, and the requirements for throughput are also getting higher and higher. The Institute of Electrical and Electronics Engineers industry standard IEEE802.11 has defined a series of the most common WLAN technical standards such as 802.11a, 802.11b, and 802.11g, and then other task groups have emerged one after another, dedicated to the development of existing 802.11 Specifications for technical improvements, for example, the 802.11n task group puts forward requirements for high throughput (High Throughput, HT), introduces multiple-input multiple-output (Multiple-Input Multiple-O...
