As shown in figure 9, the website 900 of embodiment according to the present invention, comprising: WLAN as shown in Figure 8
Communication device 800.
In conclusion technical solution of the present invention is mainly the MCS and transmission power for providing M-BA.Specifically, M-BA is adopted
With with the duplicate MCS mode of trigger frame and transmission power.Meanwhile M-BA can be identified with a bit in trigger frame
It will will use the MCS mode as trigger frame.It is also possible to use the bit or another bit is arranged to identify
M-BA will will use the transmission power as trigger frame.Since M-BA uses the MCS mode and transmitting as trigger frame
Power, therefore can guarantee that all websites can receive M-BA.
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..Further, it is also possible to marker be arranged in trigger frame, to indicate that the M-BA of subsequent transmission will be adopted
With MCS mode identical with trigger frame.
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.Upstream data therein
Frame can be the individual data frame that website 2 is sent to access point 1, be also possible to continuous multiple numbers that website 2 is sent to access point 1
According to frame.
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, used by the MCS mode and trigger frame that are used when generating M-BA
MCS mode is identical；The transmission power of M-BA is identical as transmission power used by trigger frame.
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.
