[802SEC] Comments/request for clarification/modification on the .16h PAR
Roger (and EC
members),
While 802.22
believes that coexistence is a good thing (in fact, as you know, the scope of
our PAR requires coexistence with the primary TV broadcast service and other
licensed users in spectrum allocated to the TV broadcast service),
802.22 does
have some comments and a request for clarification/modification of the .16h
PAR.
While the title
mentions only unlicensed coexistence, and it was my understanding that the scope
was to be limited to unlicensed vs. unlicensed coexistence, the PAR (attached)
indicates in its scope:
13. Scope of Proposed
Project:
This amendment specifies improved mechanisms,
as policies and medium access control enhancements, to enable
coexistence among license-exempt systems based
on IEEE Standard 802.16 and to facilitate the coexistence of
such
systems with primary
users.
It is unclear to us
what primary users in what band(s) are being referred to in the
scope.
We are concerned
that there is an ambiguity in the scope that would potentially create a
situation where 802.16 might assert that the scope of this PAR enables
it to develop systems designed to operate on an unlicensed basis in the TV
bands, which is clearly the scope of the 802.22 PAR and would, in our view,
create a situation that would run afoul of "distinct identity" and the principle
of not duplicating work.
One .16 member
indicated to me that the reference to "primary users" was intended to refer to
radars and other primary users in the 5 GHz unlicensed bands ... if this is the
intent, clarification in the scope to that effect would mitigate our
concerns.
Additionally,
section 16
(16. Are there
other documents or projects with a similar scope?)
is answered "No" and we believe that a mention of the scope of the
802.22 PAR and a statement that the 802.16h PAR would not conflict with our
scope would be appropriate.
