Re Response to TG3a Chair request for
affirmation of commitment. Abstract The
authors of the Merger 2 Proposal (DS-UWB) affirm
their commitment to working in good faith with
the 802.15 TG3a to develop an Alternate PHY layer
Standard that meets all of the requirements for
the authorized work project. These include
meeting the technical and application
requirements identified by the TG 3a members, as
well as the requirements entailed by the IEEE 802
Standards Association Purpose To help the TG3a
members understand the intentions of the Merger
2 Proposal team and ensure a clear understanding
of the technical and legal requirements for the
TG3a Alternate PHY project. Notice This
document has been prepared to assist the IEEE
P802.15. It is offered as a basis for discussion

Requirements for TG3a PHY Regarding the 15.3 MAC

• Extracts from the various documents governing the
  TG3a Alt-PHY project and direct responses from
  the Merger 2 Proposal team affirming commitment
  to the requirements contained therein
• List of requirement sources
• 15.3a Project Authorization Request (PAR)
• 5 Criteria Document
• 15.3a Requirements Document
• 15.3a Selection Criteria
• 802.15.3 Standard (PICS)

3
Requirements from the 15.3a PAR

• 13. Scope of Proposed Project
• This project will define an alternative PHY
  clause, in the frequency range of up to 24GHz,
  for a higher data rate amendment to standard
  802.15.3.
• 14. Purpose of Proposed Project
• The intent of this project is to provide a
  standard for a low complexity, low cost, low
  power consumption alternate PHY for 802.15.3
  (comparable to the goals for 802.15.3). The data
  rate will be high enough, 110 Mb/s or more (see
  18a), to satisfy an evolutionary set of consumer
  multi-media industry needs for WPAN
  communications. The project will address the
  requirements to support multimedia data types in
  multiple compliant co-located systems and also
  coexistence (18b).

Merger Proposal 2 Response

• The Authors of the Merger 2 Proposal (DS-UWB)
  affirm their commitment to creating an
  alternative PHY for the 802.15.3 Standard
• Specifically, we are committed to work to create
  a low complexity, low cost, low power alternate
  PHY for 15.3 to satisfy the requirements for WPAN
  multi-media communications applications

5
Requirements from the TG3a 5 Criteria Document

• 2.0 COMPATIBILITY
•  
• IEEE 802 defines a family of standards. All
  standards shall be in conformance with IEEE 802.1
  Architecture, Management and Inter-working. All
  LLC and MAC standards shall be compatible with
  ISO 10039, MAC Service Definition, at the LLC/MAC
  boundary. Within the LLC Working Group there
  shall be one LLC standard, including one or more
  LLC protocols with a common LLC/MAC interface.
  Within a MAC Working Group there shall be one MAC
  standard and one or more Physical Layer standards
  with a common MAC/Physical layer interface. Each
  standard in the IEEE 802 family of standards
  shall include a definition of managed objects,
  which are compatible with OSI systems management
  standards.
•  
• Note This requirement is subject to final
  resolution of corrections and revision to current
  ISO 10039, currently inconsistent with ISO 8802
  series standards.
•  
• The MAC (Medium Access Control) Layer of the
  Alternate PHY Standard will be compatible with
  the IEEE 802 requirements for architecture,
  management, and inter-networking and will be
  based upon the IEEE802.15.3 MAC.

6
Merger Proposal 2 Response

• The Authors of the Merger 2 Proposal (DS-UWB)
  affirm their commitment to creating an Alternate
  PHY standard that will meet the IEEE 802
  requirements for architecture, management and
  internetworking and which will be based on the
  802.15.3 MAC

7
Requirements from the TG3a Requirements Document

• 9.0 Supplements to 802.15.3 functionality
• It is envisioned that the alt-PHY project will
  allow supplements to 802.15.3. In addition to the
  PHY itself, the project may include MAC
  functionality necessary to support the selected
  PHY.
• It is required that the alt-PHY operate with the
  802.15.3 MAC without fundamental change in
  operation. It is also required that any
  enhancements or modifications are enabled by
  reference to alt-PHY specific PIB parameters.
• As an example, from the project request, document
  01/532r0 (alt-PHY study group proposal), location
  awareness is considered as a possible feature of
  certain alt-PHY technologies and is an example of
  supplemental MAC functionality. Such a provision
  may be supported by the PHY PIB parameters in the
  proposed 802.15.3 standard MAC or via
  supplemental MAC capabilities provided by the
  alt-PHY project.

Merger Proposal 2 Response

• The Authors of the Merger 2 Proposal (DS-UWB)
  affirm their commitment to creating an alt-PHY
  that operates with the 802.15.3 MAC without
  fundamental change in its operation.
• We are committed to creating and alt-PHY that
  requires nothing beyond supplemental MAC
  functionality based on specific alt-PHY technology

9
Requirements from the TG3a Selection Criteria

• 4. MAC Protocol Supplements
• 4.1    Alternate PHY Required MAC
  Enhancements and Modifications
• 4.1.1. Definition
• Supplements and modifications to the MAC may be
  required to accommodate the alternate PHY. It is
  preferred that the supplements be additions which
  expand the solution capability as opposed to
  changes in the MAC that represent an alternative
  way to do a particular function.

10
Merger Proposal 2 Response

• The Authors of the Merger 2 Proposal (DS-UWB)
  affirm their commitment to creating an alt-PHY
  that operates with the 802.15.3 MAC without
  fundamental change in its operation
• In particular, We are committed to creating and
  alt-PHY that supplements 802.15.3 MAC
  functionality only, and does not contain any
  changes in the MAC that represent an alternative
  way to do a particular function

11
Merger Proposal 2 Support for Simultaneous
Operating Piconets

• The Authors of the Merger 2 Proposal (DS-UWB)
  affirm their commitment to creating an alt-PHY
  that operates with the 802.15.3 MAC that provides
  the simultaneous operating piconet (SOP)
  capabilities as required by the 15.3a
  Requirements document and Selection Criteria
• In particular, we are committed to creating and
  alt-PHY that support SOP operation with a minimum
  of four supported SOP (optional support for up to
  a total of 12 piconets at this time)
• This support includes the required functionality
  to support all security features provided by the
  802.15.3a MAC

12
The 15.3a PICS

• The 802.15.3 Protocol implementation conformance
  statement (PICS) define which MAC sub-layer
  functions frames are required for compliant
  15.3/15.3a devices
• These PICS specify MAC functions such as
• Device association and dissociation
• Medium access techniques
• Beacon generation support
• Etc.
• There functions are fundamental to the MAC
  operation as defined in the 15.3 standard and
  must be supported by any Alt-PHY standard
  developed for use with the 15.3 MAC

13
Merger Proposal 2 Response

• The Authors of the Merger 2 Proposal (DS-UWB)
  affirm their commitment to creating an Alternate
  PHY standard that will provide the functionality
  required to implement a compliant 15.3a device
  based on the 15.3 MAC, as defined in the 802.15.3
  PICS specification
