Abstract
This contribution raises some comments to the WS
coexistence PAR described in 19-09-0060-00 and
proposes the way to resolve these comments

Title
• In general, we feel comfortable with the title in 19-090060-00
– Standard for TV White Space Coexistence Mechanisms
• We propose one more option to consider with differnet
wording
– IEEE Standard for coexistence mechanisms for operation in the
white spaces of the TV bands
Submission

September 2009
Scope (1/5)
• Scope in 19-09-0060-00
– The standard will specify mechanisms for coexistence amongst
dissimilar TV Band Devices and dissimilar or independently
operated networks operating in the US FCC defined TV White
Space Bands.
Submission
Slide 4
Stanislav Filin et al, NICT

September 2009
Scope (2/5)
• Comments
– From this scope it is not clear whether “mechanisms” will be
specific to particular radio interface specification or they will be
media access independent
• It is better to specify this in the scope
• We believe these mechanisms should be media access independent
– From this scope it is not clear whether only 802 wireless networks
are considered or non-802 wireless networks are also considered
• It is better to specify this in the scope
• Actually, similar statement is in Need in 19-09-0060-00
Submission
Slide 5
Stanislav Filin et al, NICT
doc.: IEEE 802.19-yy/xxxxr0
September 2009
Scope (3/5)
• Comments (continued)
– When several secondary networks operate in white space, there is a
question on how to enable fair use of this white space by these
networks
• We believe 802.19 is perfect place to address this question
• So, we propose to include this in the scope
• Actually, this corresponds to “etiquette” in Explanatory Notes in 1909-0060-00
– Coexistence between secondary networks is only one coexistence
scenario
• Another important coexistence scenario is coexistence between
primary and secondary networks
• We propose to include this scenario to the scope
Submission

Scope (4/5)
• Comments (continued)
– This scope is limited to USA market only
• We do not see any strong rationale to limit the standard only for the
USA
• If USA is mentioned in the scope, it is still possible to define a
standard for operation in the USA only
Submission

Scope (5/5)
• Proposed scope
– This standard defines extensible media access independent
mechanisms for 802 and non-802 wireless networks operating as
secondary users in TV white space to facilitate coexistence
between secondary users, fair use of white space by secondary
users, and enhanced protection of primary users from harmful
interference from secondary users.

Purpose (1/3)
• Purpose in 19-09-0060-00
– The purpose of the standard is to enable the family of IEEE 802
Air Interface Standards to most effectively use TV White Space by
providing standard coexistence mechanisms. This standard
addresses coexistence for IEEE 802 networks and may also be
useful for non IEEE 802 networks in TV White Space.
Submission
Slide 9
Stanislav Filin et al, NICT

September 2009
Purpose (2/3)
• Comments
– We believe that purpose should mention three key points proposed
for the scope in the previous slides
• Coexistence between secondary systems
• Enhanced protection of primary systems
• Fair use of white spaces
– Also, it is better to mention what are the economical benefits for
manufacturers and consumers of “TV WS Coexistence” equipment
Submission
Slide 10
Stanislav Filin et al, NICT

September 2009
Purpose (3/3)
• Proposed purpose
– This standard facilitates cost-effective and multi-vendor production
and operation of a system which will enable multiple 802 and non802 wireless secondary networks to coexist in white spaces of TV
bands, including coexistence among these networks and enhanced
protection of primary users. Also, such system will provide
mechanisms enabling efficient and fair use of white spaces of TV
bands by multiple secondary networks.

Need for the project (1/3)
• Need for the project in 19-09-0060-00
– Existing IEEE 802 standards groups are working to develop
modifications of their standards to comply with the regulatory
rules for accessing TV White Space. Mechanisms that allow these
revised standards to coexist are needed. The work proposed here
will result in standard overlay mechanisms that allow these
different 802 standards to coexist in TV White Space. It will also
seek to allow coexistence with other well established non IEEE
802 wireless standards.

Need for the project (2/3)
• Comments
– We believe that need for the project should mention three key
points proposed for the scope in the previous slides
• Coexistence between secondary systems
• Enhanced protection of primary systems
• Fair use of white spaces
– Also we believe that wording should be stronger
Submission
Slide 13
Stanislav Filin et al, NICT

September 2009
Need for the project (3/3)
• Proposed need for the project
– Given that USA FCC regulations has allowed secondary operation
in white spaces of TV bands and other countries regulatory bodies
are considering their actions regarding TV white space, it can be
expected that many 802 and non-802 wireless networks will be
operating in white spaces of TV bands in the future.
Correspondingly, questions of coexistence in white spaces and fair
use of white spaces will arise. The proposed standard will provide
mechanisms addressing these questions. Also, the proposed
standard will provide mechanisms for enhanced protection of
primary users from harmful interference from secondary users.

Standards or projects with
a similar scope (1/3)
• Text in 19-09-0060-00
– It appears that there may be related work going on in The TV
White Space Data Base Group, 3GPP, OMA, and SCC 41. These
will be explored and if there is material that would be valuable for
this effort, it will be incorporated.

the PAR

Explanatory notes (1/3)
• Text in 19-09-0060-00
– The coexistence mechanisms that will be standardized will address
the following and related areas:
•
•
•
•
Discovery …
Connection …
Logical mechanism…
Etiquette…
– These mechanisms will include ways to assure that they are
correctly functioning.
– The term “dissimilar networks”…

Explanatory notes (2/3)
• Comments
– Our concern is that the text in 19-09-0060-00 limits the scope of
the project by describing specific mechanisms
– We do not see any strong rational for such limitation at this early
stage, when project has not started yet

explanatory notes
