[STDS-802-16-MOBILE] Initial Ranging

[Ramkumar MV <ramkumar4u@GMAIL.COM>]

Hi all,
1) Is the initial ranging mandatory for every frame.
   Or is it possible to do ranging only for selected frames.
2) Can we have different ranging channels for different segments.
   Or is it mandatory to have 6 or 8 subchannels in a cell, where in
each segment have to  share the same 6 subchannels, in a frame.

  thank you very much
  with regards

  Ramkumar
