Art is to improve greatest physical layer transfer rate or network maximum throughput.Such as, 802.11ac technology is passed through
The technology such as the MIMO (multiple-input and multiple-output) introducing bigger channel width, higher order, data rate
More than 1Gbps can be reached.But, along with the increase of network density and increasing of number of users, WLAN
The efficiency of network there will be the trend being decreased obviously, and the problem of network efficiency can not be transmitted by raising merely
Speed solves.Therefore, ieee standard tissue set up TGax group of task be devoted to solve WLAN
Network efficiency problem.
In WLAN, AP (access point, access point website) and being associated with this AP
Multiple non-AP STA (non-AP Station, non-access point website) constitute a BSS (basic
Service set, Basic Service Set).
In the wlan standard (IEEE 802.11a/g/n/ac) of current main-stream, physical layer uses OFDM
(Orthogonal Frequency Division Multiple, OFDM) modulation technique, each time
The integral multiple that wireless signal-path band width is primary bandwidth 20MHz (20/40/80/160MHz) that communication uses,
But owing to wireless channel exists the build-in attribute of a coherence bandwidth, and its coherence bandwidth is generally much less than
20MHz, thus in once communication, transmitting-receiving side uses complete 20MHz and the nothing of bigger bandwidth
Line channel, can cause the availability of frequency spectrum low.
TGax group of task introduces OFDMA (Orthogonal Frequency Division Multiple
Access, orthogonal frequency-time multiple access) as the major technique of next generation wlan standard, carry with this
High spectrum utilization.At present in research on standard progress, 20MHz bandwidth is divided into multiple little bandwidth,
AP can simultaneously with multiple non-access point site communication, each non-access point website can use one or
The multiple little bandwidth of person, the use of non-access point website is several and which little bandwidth needs AP to send out relevant
Control information indicates.
In a wlan, instruction information generally uses fixing number of bits, and uses bitmap position
The mode of figure, if in 802.11ax standard, resource instruction still uses this pattern, its ratio taken
Special quantity will be the most, particularly in channel width more than 20MHz and STA (website) number relatively
In the case of Duo;The most each 20MHz channel width is divided into 9 schedulable little bandwidth, at 80MHz
Under channel width, the little bandwidth of schedulable independence has 36, if using simple bitmap pattern the most every
One Resource Block takies a bit, if there are 4 STA, each STA will use 36 bits,
Amount to 144 bits, and in order to improve the reliability of the control information transmission such as scheduling in WLAN,
Generally use code modulation mode MCS (Modulation and Coding Scheme, the tune of relatively low rate
Make and coding strategy) it is transmitted, this allows for the transmission time relative data transmission that instruction information takies
The ratio of time improves, and then efficiency of transmission is reduced.
