Background technology
In the related, propose in WiFi technology, improve the vision of the effective rate of utilization of frequency spectrum.And based on emulating the technology of WIFI communication process, at same BSS(Basic ServiceSet, Basic Service Set) in, if there is the STA(Station supporting 802.11n and 802.11b standard simultaneously, website or terminal), the throughput of so whole BSS is relative to the throughput degradation at least 96% of the BSS that only has the STAs supporting 802.11n standard to form.
Owing to supporting that the STA of various criterion can exist unavoidably simultaneously, thus in order to avoid the generation of above-mentioned situation, the application compares the frame format under the such as various criterion shown in Figure 1A to Fig. 1 C.
Figure 1A is depicted as the frame format of non-high-throughput pattern (Non-HT), and physical frame head part comprises original Short Training territory (L-STF), original long training domain (L-LTF) and original signal domain (L-SIG) etc.; Data field (DATA) then contains the data division of above-mentioned mac frame part and the required transmission of reality.
Figure 1B is depicted as the frame format of mixed mode (HT-mixed format), physical frame head part comprises original Short Training territory (L-STF), original long training domain (L-LTF), original signal domain (L-SIG), high-throughput signal domain (HT-SIG), high-throughput short signal territory (HT-STF) and the long signal domain of high-throughput (HT-LTF comprises the HT-LTF of data type and extended pattern); And data field (DATA) is identical.

Wherein, when only have in BSS support that the STA of 802.11n exists time, communication is the frame format adopting high-throughput mode, and adopts higher MCS(Modulation and CodingScheme, modulating-coding strategy) mode; When there being the STA of 802.11n and 802.11a/b/g to exist in BSS simultaneously, supporting that the STA of 802.11a/b/g standard adopts the frame format of non-high-throughput pattern to communicate, support that the STA of 802.11n standard then adopts the frame format of mixed mode to communicate.
As can be seen from frame format, if in the BSS of mixing, in order to the compatibility in first standard, support that the STAs of 802.11n standard can only adopt the frame format of mixed mode to communicate, L-STF and L-SIG part has been had more, unnecessary fixed overhead that Here it is relative to the frame format of high-throughput mode; Simultaneously much lower in the throughput of the BSS of single 802.11n or 802.11ac of same long call duration time internal ratio.

Such as in the embodiment shown in figure 3b, support in region that the quantity of the STA of 802.11n is greater than the STA supporting 802.11a/b/g, then length and the length of non-competing period phase 2 of competing period phase 2 are accordingly greater than period competition phase 1 and non-competing period phase 1 respectively.
Fig. 3 C shows the schematic diagram of the distribution condition to competition phase and non-competing phase according to another embodiment of the invention.
