laa-wifi-indoor simulatenous transmissions

[m.alh...@gmail.com]

Hello,

I run the laa-wifi-indoor scenario and i got the phy log for laa as attached. I wanna ask as can be seen from the log file that there are some sender nodes as node 0 and node 2 in the first two rows send the data at the same time! how is that can be done while we are using the same channel?!. My question is if simulatenous transmissions are done from same cell or not?? and if this is done from the same cell how?!!

Regards.
