Description
Technical field
The present invention relates to fields of communication technology, wireless in particular to a kind of communication means of WLAN, one kind
The communication device of local area network, a kind of access point and a kind of website.
Background technique
Study group HEW (the High efficiency of next-generation Wi-Fi technology has been set up in May, 2013,802.11
WLAN, efficient WLAN), i.e. 802.11ax, main research point is the handling capacity for improving existing Wi-Fi technology, improves
The effective use efficiency of frequency spectrum improves user experience and service quality Q oE (Quality of Experience), and realizes
Than the communication environment that existing Wi-Fi technology adapts to more crypto set.
During standard formulation, for PPDU (Physical Layer Convergence Procedure
(PLCP) Protocol Data Unit, physical layer convergence procedure protocol Data Unit) the SIG-A field in physical header is made that
Specific definition, SIG-A field include BSS (Basic Service Set, basic service set) color subfield, BSS
Color is expressed as the mark of base station, and effect is to allow website that can preferably distinguish the data of this BSS and the number of other BSS
According to.
Only existed in 802.11ah MU (Multi-user multi-user) format (format) and SU (Single User,
Single user) format both data frame formats, and the value of its BSS color field be always maintained at it is constant.
802.11ax application scenarios ratio 802.11ah more crypto set, also means that and exists in 802.11ax communication environment
More OBSS (Overlapping BSS, overlapping basic service set).And three kinds of data are defined in 802.11ax
Frame format is MU format, SU format and Extended Range SU (referred to as single user extended distance) respectively
Format, and the transimission power that Extended Range SU format is used in transmission is other data frame transfer power
2 times.Therefore, BSS color value does not change always the application scenarios for being not particularly suited for 802.11ax.
As shown in Figure 1, an AP has been likely to form different BSS when transmitting different data, for example in transmission single user
When extended distance data frame (i.e. Extended Range SU PPDU), BSS1 is formd, when transmitting other data frames, is formed
BSS0.And the communication of BSS1 can interfere the communication of BSS2, and the communication of BSS0 will not then make the communication of BSS2
At interference.
For communication scenes shown in FIG. 1, if in the data transmission using as BSS color value is always in 802.11ah
Constant technology, not only can communication band to itself interfere, nor adapt to CCA (Clear Channel
Assessment, channel idle detection) value change mechanism (due to BSS range shorter or becoming larger or change CCA value).
