802.19 new standard for TV white space coexistence mechanisms, PAR and 5 C

• 2.1 Title: Standard for Information Technology - Telecommunications and Information Exchange Between Systems - Local and Metropolitan Area Networks - Specific Requirements - Part 19: TV White Space Coexistence Mechanisms– Situation #1: Title includes “Coexistence Mechanism”, – Problem: The PAR and 5C does not define what “Coexistence

Mechanism” is.– Suggested Fix: In the PAR and 5C define what “Coexistence

Mechanism” really is.• Straw Poll: Submit to .19: 14 yes, 2 no, 11 abstain

Submission

802.19 2.1 Title– Situation #2: The title specifies that this a Standard.– Problem: We do not believe it should be Standard. The level of

evidence provided for Feasibility in the 5C does not justify a Standard• The 5C does not identify any existing proven similar “coexistence

mechanisms” in any unlicensed bands.– Suggested Fix. Make this PAR for a Recommended Practice to

provide 802.19 group an opportunity to demonstrate the feasibility• A Recommended Practice has a trial use aspect that should be

addressed.• Typically the technical rigor that is employed in creating documents

increases as you go from Guides -> Recommended Practices -> Standards.

802.19 (cont)

• 5.4 Purpose: The purpose of the standard is to enable the family of IEEE 802 Wireless Standards to most effectively use TV White Space by providing standard coexistence mechanisms among dissimilar or independently operated TVBD networks and dissimilar TVBDs. This standard addresses coexistence for IEEE 802 networks and devices and will also be useful for non IEEE 802 networks and TVBDs.

802.19 (Cont)

• 5.5 Need for the Project: Existing IEEE 802 standards groups are developing standards and amendments, to comply with the regulatory rules for use of TV white space. Other non-IEEE 802 wireless standards for use of the TV White Space are also in development. In order for these various dissimilar TVBD networks and devices to effectively coexist in the TVWS spectrum, fair and efficient spectrum sharing is needed. Fair and efficient spectrum sharing among dissimilar TVBD networks and devices may require the coexistence mechanisms provided in this standard. In order to enhance utilization of the TV White Space bands standardized coexistence mechanisms are needed. Mechanisms such as those discussed in the explanatory notes may be considered.

• 5.6 Stakeholders for the Standard: Designers of TVWS MAC/PHY standards and implementations.

Submission

802.19 (Cont)• 8.1 Additional Explanatory Notes (Item Number and Explanation): • Section 5.2 (Scope)

– The term “dissimilar” used in this document refers to the networks and devices, which use different radio technologies adapted for TV White Space Frequency Bands.

• Section 5.2 (Scope)– The term “independently” operated used in this document refers to

networks which may or may not use the same radio technology but are operated by independent entities which do not necessarily have a business relationship for coordinating their use of TV White Space Frequency Bands; furthermore, such similar radio access technologies may not have an otherwise available means of coexistence. For example, this differentiates independently operated from a situation in which a single administrative authority manages the coexistence between dissimilar technologies deployed in a composite network.

802.19 -- 8.1 Additional Explanatory Notes (Cont)

• Section 5.2 (Scope):• The term "TVBD" is the FCC term for TV Band Device

which refers to any device which complies with FCC rules to allow unlicensed radio transmitters to operate in the broadcast television spectrum at locations where that spectrum is not being used by licensed services. A TV band device (TVBD) is a low power transmitter that operates on an unoccupied TV channel in the range of channels 2-51, excluding channels 3-4 and 37.

Submission

802.19 8.1 Additional Explanatory Notes (Cont)• Sec. 5.5 (Need):

– The radio technology independent coexistence mechanisms that are standardized may address the following and related areas:

• Discovery is the process of determining that there are two or more dissimilar and independently operated wireless networks or devices attempting to use the same White Space frequency range in the same location. This can occur in two ways. The two networks or devices may attempt to enter at the same time or one may be present and a second seek to enter. In the second case, a network operating in White Space, must periodically check for new entrants and a new entrant must check before entering.

• A Connection for coexistence may be useful for two dissimilar and independently operated wireless networks or devices to exchange information in order to share spectrum.

• A Logical Mechanism for Promoting Coexistence is a mechanism that involves the exchange of information between different dissimilar or independently operated networks or devices and may also involve algorithms seeking to maximize the quality of service for all participants.

Questions – Issues to 802.19 (2)• 5. – Please review doc 11-09/1107 and respond to the

comments/sticky notes.• 6. Position as 802.11 – Should it be a Recommended Practice or a

Standard?• 7. The PAR does not justify the need for a Standard.

– Suggesting a Messaging system rather than a physical system.– Power consumption considerations.– Data plane system that does not change the MAC/PHYs, so the relative

rates that are needed to match for communication between the disparate systems is not shown.

• 8.Confusion on what the proposed PAR will actually change?– It is not clear if 802.19 is going to propose another MAC/PHY or just

provide a layer-3 and above specification. • 9. Title is very ambiguous as to what the “Coexistence

Mechanism” really are?– Is this requiring a new MAC/PHY or changes to existing 802 WGs.

802.19 (3)

• 10. From the 5C the following statement needs to be clarified as to what changes to the 802 WGs are going to be targeted.– This standard will not require changes to any existing 802 MAC

SAP definitions, ensuring that all LLC and MAC interfaces are compatible to and in conformance with the IEEE 802.1 architecture, management and internetworking standards.

• 11 – It is implied that a Standard will be imposed on all the 802 WG after ratification, and what changes may be required is unknown.– Provide more detail on what the expectation is that justifies this

being a Standard rather than a Recommended Practice.

• Item 1: Doc 11-09/1105r1 – submission that has some discussion on the rational for changing the scope.

• Item 2: Problem: Dates for completion are not realistic. The dates need to be corrected (we suggest that the dates of Start Sponsor 12-2012 and RevCom 12-2013 would be more realistic/acceptable.)

• Item 3: the form presented was not the correct PAR form. The PAR modification form should be used.

802.22 (3)• 8.1 other comments:

– Issue 5: Remove the following text as it is no longer necessary/needed from the end of the first paragraph:• “The IEEE 802.18 Study Group chartered to develop this PAR does not

believe that any existing IEEE 802 PHY/MAC combination can meet these requirements without extensive modifications. The Study Group has therefore concluded that placing the project in a new WorkingGroup is the most efficient approach..”

• 5c: Distinct Identity A– Issue 6: This text fails to distinguish among 802.16h, which will

be an approved amendment in early 2010, and 802.22 and the efforts proposed in the 802.22.3 PAR. Add distinctions between each of the three. Be aware that 802.16h clause 6.3.2.3.86 does report DTV, wireless microphones and other licensed users.

802.22 (4)

• 5C Technical Feasibility –– Issue 7: There is no experience of WLAN devices operating under

the control of fixed outdoor devices reliably, and indeed the question of reliable operation without common control is an issue in every unlicensed band.

• 5C Economic Feasibility –– Issue 8: Not all devices are autonomous, indeed the FCC ruling

requires that Master Devices contact the TV bands database before any transmission is allowed. Change this text to include operation with a TV bands database.

and Physical Layer (PHY) specifications: Policies and procedures for Scalable operations of Wireless Regional Area Networks (WRAN) in the TV Bands.

– Issue 1: delete “Policies and procedures for “ from the title. This is a standard for…

– Issue 2: The full title is not listed in the PAR form.. It should have the Boiler Plate from 802 followed by “Part 22” followed by the designation that this is for the “WRAN..” and then the specific designation of what is being covered.

802.22.3 (3)

• Technical Feasibility– Issue 6 : the statements are very broad, and in some cases not accurate…” Existing 802

wireless standards in other bands (e.g. 802.11h) have demonstrated that detection and avoidance of operation in spectrum occupied by licensed  users is technically feasible.”

The 802.11h does not do detect and avoid (DAA) it only specified DFS and TPC.

–  Issue 7: The statements should address the “demonstrated” technology that show the technical feasibility.

– Issue 8: The addition of “Scalable” as the main focus, should be addressed in the 5C to show the distinct difference from the base 22 standard.

– Issue 9 (to be renumbered as #1): If 802.22.3 is an extension of 802.22, and creating a “Scalable” extension of the standard, then this should be an amendment. The Amendment should be created after the standard is approved to allow a consistent target for the amendment to modify.
