Particularly, as shown in Figure 1, the Wireless LAN communication method corresponding to the transmit leg of message frame according to an embodiment of the invention, comprising:
Step 102, generating messages frame, at least comprise sub-channel allocation information in described message frame, described sub-channel allocation information represents that current communication channel is divided into multiple subchannel, and the recipient of described message frame be assigned to use specific subchannel communicate;
Step 104, sends described message frame.
Wherein, communication channel can for the working channel divided, its concrete bandwidth can be 20MHz, 40MHz, 80MHz, 160MHz etc., can be for example the subchannel that the working channel of 20MHz is divided into 4 5MHz bandwidth by bandwidth, also can be the subchannel that the working channel of 20MHz is divided into other quantity certainly according to demand by bandwidth.
2, the intended recipient of message frame
The intended recipient of message frame and above-mentioned AP1 need the STA carrying out with it communicating, and be now such as the STA1 of supposition, AP1 achieves the subchannel batch operation to STA1 by this message frame just.
Particularly, as shown in Figure 2, the Wireless LAN communication method corresponding to the recipient of message frame according to an embodiment of the invention, comprising:
Step 202, receipt message frame, at least comprise sub-channel allocation information in described message frame, described sub-channel allocation information represents that current communication channel is divided into multiple subchannel, and the recipient of described message frame be assigned to use specific subchannel communicate.
By the Further Division of AP1 to communication channel, make certain sub-channels that can only use between STA1 and AP1 in this communication channel, namely the part in the whole frequency spectrum resource of this communication channel is only taken, other STA then can adopt all the other frequency spectrum resources in same communication channel to realize the communication process with AP1 or other AP, thus realizing while the making full use of of frequency spectrum resource, by the strict division of sub-channel, can avoid producing interference between multiple STA, contribute to improving the availability of frequency spectrum.
3, other recipients of message frame
When message frame be multicast message frame or broadcast message frame time, except above-mentioned as except the intended recipient such as STA1, other communication equipments also may receive this message frame.As a kind of comparatively concrete situation, such as this message frame is received by other AP, is assumed to AP2.So, for AP2, based on the message frame from AP1 received, the distribution condition of its sub-channel can be known, thus determine that the subchannel how performing self distributes.
Particularly, as shown in Figure 3, the Wireless LAN communication method corresponding to the recipient of message frame according to another embodiment of the invention, comprising:
Step 302, receipt message frame, at least comprise sub-channel allocation information in described message frame, described sub-channel allocation information represents that current communication channel is divided into multiple subchannel, and the intended recipient of described message frame be assigned to use specific subchannel communicate; And
Step 304, uses other subchannels in described current communication channel to communicate, and wherein, other subchannels described are different from described specific subchannel.
AP1 is the transmit leg of message frame, by the Further Division to communication channel, and its division and the situation that takies are broadcasted, make certain sub-channels that can only use between STA1 and AP1 in this communication channel, namely the part in the whole frequency spectrum resource of this communication channel is only taken, other STA then can adopt all the other frequency spectrum resources in same communication channel to realize the communication process with AP1 or other AP, thus realizing while the making full use of of frequency spectrum resource, by the strict division of sub-channel, can avoid producing interference between multiple STA, contribute to improving the availability of frequency spectrum.
In addition, except the raising for the availability of frequency spectrum, can also realize: on the one hand, as the real transmission target of this message frame, namely need the STA1 carrying out communicating, can recognize and need to use which subchannel to communicate, to avoid clashing with other equipment and disturbing; On the other hand, as other recipients of this message frame, such as AP2, can reasonably arrange according to the division of sub-channel and the situation that takies and dispatch, to avoid, at synchronization, other STA are dispensed to the identical subchannel of use, avoid clashing and disturbing.
Fig. 4 shows the schematic diagram divided communication channel according to an embodiment of the invention.
As shown in Figure 4, as one comparatively specific embodiment, being such as the communication channel CH36 of 20MHz for bandwidth, can be subchannel (Subchannel) 1, subchannel 2 by its Further Division ... subchannel n.Particularly, for the number of sub-channels that each communication channel divides, can adjust according to the communication speed etc. of the data volume when channel communication quality of such as reality, communication, needs, such as when in the more high situation of communication speed that channel communication quality is lower, data volume is comparatively large, need, number of sub-channels can be reduced, increase the bandwidth of every sub-channels, to guarantee the smooth realization of communication process.
Certainly, for every sub-channels, its amount of bandwidth can be identical, contributes to simplifying division operation, and can meet the communication process of multiple devices coequally; Or also can be different, thus meet different communication requirements.
And divide based on subchannel similar to Figure 4, still for above-mentioned AP1 and STA1, the subchannel distributed specifically may be used for: initial connection establishment process or carry out data communication, and namely described sub-channel allocation information represents that the recipient of described message frame is assigned to and uses described specific subchannel carry out initial connection establishment process or carry out data communication.
