[Discuss-gnuradio] 802.11ah PHY using gr-ieee-802-11

Hi,
We have been working on 802.11ah PHY implementation.
2MHz operation of 802.11ah requires 52 data subcarriers instead of 48 in 802.11a/g.
Would changing the carrier index in ofdm carrier allocator block suffice.?
Kindly guide for making proper changes..

In the carrier allocator block all carriers are specified instead of data sub carriers alone..is this correct?
Thanks
