Problems solved by technology

[0007]However, if the access point carries the sending interval of the next trigger frame in each trigger frame, since the trigger signaling of the trigger frame is located in its physical layer preamble, However, this part of the signaling resources is relatively precious, so it will bring a large signaling overhead, and for a certain trigger frame, if the station fails to receive it successfully, it will not be able to obtain the sending time of the next trigger frame, so the reliability is poor

Embodiment 1

[0244] An embodiment of the present invention provides a method for sending an uplink multi-user transmission trigger frame, which is applied to an AP, such as figure 2 As shown, the method includes:

[0245] Step 101, the AP sends a beacon frame carrying a trigger frame information unit to the STA, the trigger frame information unit includes the sending information of the trigger frame, and the sending information of the trigger frame is used for the STA to obtain the sending of the trigger frame cycle.

[0246] Step 102, the AP acquires the target transmission time sequence of the trigger frame according to the sending period of the trigger frame.

[0247] Step 103, when the target transmission time of the trigger frame is reached, the AP contends for a channel.

[0248] Step 104, the AP sends the trigger frame to the STA after the competition is successful, and the target transmission time is any time point in the target transmission time sequence.

[0249] In the metho...

Embodiment 2

[0251] Embodiments of the present invention provide another method for sending an uplink multi-user transmission trigger frame, which is applied to STAs, such as image 3 As shown, the method includes:

[0252] In step 201, the STA receives a beacon frame carrying a trigger frame information element from the AP, and the trigger frame information element includes sending information of the trigger frame.

[0253] Step 202, the STA obtains the sending period of the trigger frame according to the sending information of the trigger frame.

[0254] Step 203, the STA acquires the target transmission time sequence of the trigger frame according to the sending period of the trigger frame.

[0255] Step 204, when the target transmission time of the trigger frame is reached, the STA transitions to an active state.

[0256] Step 205, the STA receives the trigger frame through a monitoring channel, and the target transmission time is any time point in the target transmission time sequen...

Embodiment 3

[0260] The embodiment of the present invention also provides another method for sending an uplink multi-user transmission trigger frame, which is applied to an AP, such as Figure 4 As shown, the method includes:

[0261] Step 301, the AP contends for a channel.

[0262] Step 302, the AP sends the trigger frame to the STA after the competition is successful, and the trigger frame carries indication information, and the indication information is used to indicate when the preset condition is met, after the STA completes the uplink transmission The AP will send another trigger frame to the STA within a preset time.

[0263] In the method for sending a trigger frame for uplink multi-user transmission provided by an embodiment of the present invention, the AP sends a trigger frame to the STA after the contention is successful, and the trigger frame carries indication information, and the indication information is used to indicate that when the preset condition is met, the STA comp...

Abstract

The embodiment of the invention provides a sending method of an uplink multi-user transmission trigger frame, an access point and a station, the access point sends a beacon frame carrying a trigger frame information unit to the station, the trigger frame information unit comprises sending information of the trigger frame, and the station obtains a target transmission time sequence of the trigger frame according to the sending information and sends the target transmission time sequence to the station. When the target transmission time of the trigger frame is reached, the access point competes for a channel and sends the trigger frame to the station after the access point competes successfully, the station is converted into an active state at the moment, the trigger frame is received through the monitoring channel, and the station performs uplink transmission according to the indication of the trigger frame after receiving the trigger frame. According to the invention, the station can acquire the sending time of the trigger frame under the condition of not improving the signaling overhead and ensuring the reliability, so that the station can keep a receiving state at a proper time.
