Hi, Varma and All,
Because one Band only got 4bins and 4 Bin only can make 32 data subcarriers + 4 pilot subcarriers. Any subchannel shoud have at least 48 tones(subcarriers), if we do not restrict the definition of AMC subchannel into one band. than any AMC subchannel can be exist accross the Band.
So, the meaning of "AMC subchannel consists of 6 contiguous bins in a same band" ==> one AMC subchannel should be confined with in the same band. This definition would help the system exploits the Multi user diversity.
I hope this explanation would help you.
