Figure 11 d are referred to, Figure 11 d are a kind of process signals of multi-user transmission disclosed in the embodiment of the present invention
Figure.As illustrated in fig. 11d, AP sends broadcast trigger frame triggering STA1, STA2, STA3 and carries out uplink,
Wherein STA1 sends N on RU-A resource blocksss=2 spatial flows；STA2 and STA3 is in RU-B resources
Up MU-MIMO transmission is carried out on block, and STA2 spatial stream number is Nss=2, STA3 space
Fluxion is Nss=1.The spatial flow of the broadcast trigger frame indicates same as described above.Meanwhile, AP is returned
It is up to trigger STA4 progress that STA4 sends the trigger frame (unicast trigger) of downlink data and unicast
MU-MIMO transmission, STA4 resource indicates to be also RU-B and Nss=2.Therefore, STA2, STA3,
STA4 carries out up MU-MIMO transmission on RU-B resource blocks.
Due to STA4 can only the enterprising row data of resource block and unicast trigger frame of oneself reception, it is impossible to connect
The broadcast trigger frame on another resource block is received, therefore AP is needed in the unicast trigger frame of transmission additionally
Indicate the original position N of STA4 spatial flowsss,start, N hereinss,start=4, namely STA4 selection spatial flows 4~5,
The offset also implicitly indicates that STA4 transmission mode is up MU-MIMO simultaneously.Figure 11 e are referred to,
