Hi, 

I have some question about wireless node.Whether Phy layer receive another 
packet to transmit 
when transmiting last packet,It is to say that whether there are two packets in 
Phy layer in 
the same time??

We know, The packet from LL to MAC to Phy,If mac did not receive a ACK it could 
not transmit 
next packet to Phy ,just as LL could not transmit next packet to MAC. Is it 
right?
IF it is right,the formula in mac-802.11.cc

double start_time = max(channel_idle_time_, NOW)

is always NOW,is it right??

Any proposal is OK to me ,thanks a lot :)
