The attached corespondence have been forwarded to
me this (Friday) evening.
I don't understand why such major changes in the
PAR are not discussed openly through the reflector. I was not on the list, and
so I believe could be the case for other members, observers and others.
I am totally against the changes proposed,
except for the the editorial change of 802.16a to 802.16-2004.
Backwards compatibilty should not be compromised. IMHO, it is important to keep
one foot on the ground, so the speak, namely if one implements the scaleable
OFDMA mode it has to be fully compatible with 2k BS. There was never an
intention to invent a new mode in 802.16e, that won't be fully compatible
with at least on of the existing ones. Accepting the changes would make the
other modes practically obsolete and jeopardize the efforts of the current
implementors.
I move to table the issue till the next meeting
(#32)

Paragraph #18: Change “needs to” to “shall”. Brian From:
Puthenkulam, Jose P [mailto:jose.p.puthenkulam@intel.com] Hi
All, After getting feedback
from several folks here is yet another revision of the text with more changes in
item 18. 12. Scope of Proposed Project
states This document provides enhancements
to IEEE Std 802.16/802.16a to support subscriber stations moving at vehicular
speeds and thereby specifies a system for combined fixed and mobile broadband
wireless access. Functions to support higher layer handoff between base stations
or sectors are specified. Operation is limited to licensed bands suitable for
mobility between 2 and 6 GHz. Fixed 802.16a subscriber capabilities shall not be
compromised (See Item #18). Changes
suggested:
18 Additional Explanatory Notes:
(Item Number and Explanation) Item #12 - Subscriber stations
specified herein, when stationary, shall interoperate with base stations
specified in IEEE Std 802.16a. Base stations specified herein shall interoperate
with stationary subscriber stations specified in IEEE Std 802.16a. Because the
standard will utilize the 802.16/802.16a medium access control layer, it will
support multimedia services requiring differentiated Quality of Service, and it
will support adaptive physical link control so that subscriber stations can
receive higher-rate service when they move more slowly, include more effective
antennas, or are otherwise in better link
conditions. Changes
suggested:
Thanks to Roger and
Brian for their valuable suggestions. Hope you can review and provide feedback
for this. Best

Puthenkulam, Jose P Hi All, At the Seattle Face-to-Face 802.16
Pre-meeting we discussed the need to modify the 16e PAR to remove the need for
interoperability for the Scalable OFDMA FFT profiles from 128-1k with the REVd
physical layer profiles. This is because some MSS may only implement some of the
FFT sizes based on the channel widths and currently the 2k mode is mandated in
16e for compatibility reasons and it is a difficult requirement to meet for all
solutions. Hence the following changes to the
16e PAR text were prepared at the 12. Scope of Proposed Project
states This document provides enhancements
to IEEE Std 802.16/802.16a to support subscriber stations moving at vehicular
speeds and thereby specifies a system for combined fixed and mobile broadband
wireless access. Functions to support higher layer handoff between base stations
or sectors are specified. Operation is limited to licensed bands suitable for
mobility between 2 and 6 GHz. Fixed 802.16a subscriber capabilities shall not be
compromised (See Item #18). Changes
suggested:
Reason for
deleting the last sentence was that one could not properly interpret what would
essentially compromise a 802.16a subscriber. Also as the standard upfront states
that it is an amendment there seemed to be no need for this
sentence. 18 Additional Explanatory Notes:
(Item Number and Explanation) Item #12 - Subscriber stations specified herein, when stationary, shall
interoperate with base stations specified in IEEE Std 802.16a. Base stations
specified herein shall interoperate with stationary subscriber stations
specified in IEEE Std 802.16a. Because the standard will utilize the
802.16/802.16a medium access control layer, it will support multimedia services
requiring differentiated Quality of Service, and it will support adaptive
physical link control so that subscriber stations can receive higher-rate
service when they move more slowly, include more effective antennas, or are
otherwise in better link conditions. Changes
suggested:
So this text
essentially made the scope of interoperability more
explicit. Please try your best to give
feedback by at least by Friday 5/14 morning. Thanks & best
