The transimission power of MCS and AP, and then website can transmit uplink data frames according to the transfer resource distributed in trigger frame.AP is connecing
After the uplink data frames for receiving website transmission, in order to make all websites that can correctly parse M-BA, when generating M-BA
The MCS mode of use should be all websites and carry out the minimum MCS mode used when transmitting uplink data.For example: trigger frame gives three
A website is assigned with ascending resource: the MCS mode of STA A is MCS4, and the MCS mode of STA B is MCS3, the MCS mode of STA C
For MCS3, then M-BA uses MCS3 mode.
Meanwhile in order to enhance the anti-interference ability of M-BA, all websites are set by its transmission power and carry out upper line number
The maximum transmission power used when according to transmission.Or using transmitting function used in MCS mode the smallest website when uplink
Rate.It wherein, is multiple according to the website of the smallest MCS mode, and its transmission power is different, then M-BA is using in multiple websites
Biggish transmission power.
The above process is specifically as shown in Figure 10:
Figure 10 shows the schematic flow diagram of the communication means of the WLAN of the 5th embodiment according to the present invention.
As shown in Figure 10, the communication means of the WLAN of the 5th embodiment according to the present invention, comprising:
Step 1001, access point 1 generates trigger frame.Wherein, the biography that access point 1 is distributed to website 2 is contained in trigger frame
Defeated resource, the transfer resource include access point distribution bandwidth resources, website use MCS mode, wireless resource block point
With information and spatial reuse information etc..
Step 1002, access point 1 sends trigger frame.
Step 1003, website 2 receives trigger frame.
Step 1004, website 2 obtains the transfer resource distributed in trigger frame.
Step 1005, website 2 sends uplink data frames to access point 1 based on the transfer resource got.Wherein, upper line number
The MCS mode used according to frame is MCS mode specified in trigger frame.Website 2 can determine trigger frame when receiving trigger frame
Reception power, and then uplink data frames are sent using the transmission power for corresponding to the reception power.
Step 1006, the uplink data frames that 1 receiving station 2 of access point is sent.
Step 1007, access point 1 generates M-BA.Wherein, the MCS mode used when generating M-BA should be all websites and carry out
The minimum MCS mode used when transmitting uplink data；The transmission power of M-BA is the website using minimum MCS mode in transmission
Transmission power when row data frame, or the maximum transmission power for using all websites to use when carrying out transmitting uplink data.
Step 1008, access point 1 sends M-BA.
The technical scheme of the present invention has been explained in detail above with reference to the attached drawings, and the invention proposes a kind of new WLANs
Communication plan, can for 802.11ax communication scenes to the modulation coding scheme of multi-site confirmation message frame and transmitting function
Rate is defined, and meets the communication requirement of 802.11ax, improves region handling capacity indirectly.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
