Abstract
• Editorial comments to contribution 19-10-0031r0 are
provide
• Intent is to clarify requirement
• We copy the original requirement showing
modifications in red

Summary of comments
• Separate requirements into
– What we want the standard to define
– What operation we want the resulting system to enable
• In most cases this requires only minor changes to the
original proposal
Submission

Requirement (1/7)
• Original
– P802.19.1 shall enable discovery of P802.19.1- compliant TVBD
networks and devices.
• Proposal
– P802.19.1 shall define discovery mechanisms of P802.19.1compliant TVBD networks and devices.
• Rationale
– This describes what we want the standard to define

Requirement 2/7
• Original
– P802.19.1 shall be able to analyze operational environment of
TVBD networks and devices, and determine whether coexistence
problem exist.
• Proposal
– P802.19.1 shall define methods to analyze operational environment
of TVBD networks and devices, and determine whether
coexistence problem exist.
• Rationale
– This is what we want the standard to define
Submission

Requirement 3/7
• Original
– P802.19.1 shall enable TVWS coexistence decision making.
• Proposal
– P802.19.1 shall define algorithms for coexistence decision making
by TVBD devices and networks.
• Rationale
– Clarifies that standard defined algorithms
– Algorithms intended to be used by devices and networks
implementing the standard.

Requirement 4/7
• Original
– P802.19.1 shall support centralized, distributed and autonomous
decision making for TVWS coexistence.
• Proposal (includes Yohannes’s e-mail comments)
– P802.19.1 shall define centralized, distributed and autonomous
decision making algorithms for TVWS coexistence.
– Systems implementing P802.19.1 shall be configurable using a
centralized, distributed and autonomous architectural approaches.
• Hybrid architectures shall be supported.
• Rationale:
– This seems to me to be a sticking point
– We want to state both that we will support algorithms that can support
different architectural approach
– But also that we shall support all such systems.

Requirement 5/7
• Original
– P802.19.1 shall have a means to obtain and exchange information
required to make TVWS coexistence decisions.
• Proposal
– P802.19.1 shall define mechanisms to obtain and exchange
information required to make TVWS coexistence decisions.
• Rationale
– Again, this is what we want the standard to define

Requirement 6/7
• Original
– P802.19.1 shall be able to provide reconfiguration commands and
corresponding control information to P802.19.1 TVBD networks
and devices to implement TVWS coexistence decisions.
• Proposal
– P802.19.1 shall define reconfiguration commands and control
information elements for P802.19.1 TVBD networks and devices
for the purpose of implementing TVWS coexistence decisions.
• Rationale
– States more clearly that this is something that the standard will
define

Requirement 7/7
• Original
– P802.19.1 shall be able to update information related to
coexistence and provide it to P802.19.1 compliant networks and
devices.
• Proposal
– P802.19.1 networks and devices shall be able to update
information related to coexistence and provide it to other
P802.19.1 compliant networks and devices.
• Rationale
– This is actually a requirement on the devices and networks
