[STDS-802-16] 802.16 mesh : number of minislots in the data subframe
Hi all,
If I have well understood the standard the data subframe is composed of
256 minislot. suitable especially that the demend level is coded on 8
bits.
The number of OFDM symbol is given by the formula
ceiling [(OFDM symbols per frame – MSH-CTRL-LEN * 7)/256] : A very clear formula.
If for example, we have 250 OFDM sym Frame (real case) the previous
formula would not have any sens. because we will have 256 OFDM sym in
the data subframe or the total number is 250.
I found insome articles different statements :
- that the number of minislots neddn't to be 256 (but could be up to 256).
- that we could have a minislot as a fraction of an OFDM symbol.
In any case the standard formula will not be adequate. Could someone help in this topic please.
Best regards
