History
Questions raised in (Jeff Gilbert)
PHY impairments: currently being fixed in FRCC
PHY abstraction used in MAC: to be addressed
Large consensus in Jan 6th FRCC telecon for the need of a “unified way of modeling PHY error rate in MAC simulation”

PHY Abstraction problem
PHY/MAC Interface can drastically impact overall results:
Time varying channel creates time varying PER
Affects overall delay, jitter and goodput
Challenge
Properly model detailed PHY characteristics
Keep flexibility to adapt to various PHYs
Keep simulation effort reasonable

Benefits
Transparency
Assess MAC simulation result validity
Allow cross checking
Comparability
Fair comparison between System results
Fair comparison between MACs
Merging ability
MAC and PHY from different proposers

Straw polls
Straw Poll #1:
Do we want a unified way of modeling PHY error rate in MAC/System simulation?
Straw Poll #2:
When must this be completed by?
By the time of the call for proposals
By the session following the call for proposals
The call for proposals should not be issued until this completes (by next session latest)
