Hi,

In the case of PUSC permutation mode of OFDMA, why do they adopt the
policy of renumbering ?
I searched the internet, but i do not find any specific link/doc that
talks about this in detail.
Any ideas ?

Thx in advans,
Karthik Balaguru

I got the info w.r.t PUSC permutation from http://ieee802.org/16 :-

I find that the PUSC permutation has
1) Outer Permutation and
2) Inner Permutation
Further, These permutations reduce interference .
Cross-interference between neighboring cells is reduced between
neighbouring cells,
w.r.t subchannels.

But, why have they opted for this renumbering scheme to introduce
permutation ?

Thx. I got the answers.
I find my queries answered in http://ieee802.org/16 .
