HR-MS Discovery & Association
Considerations for 802.16n
Goals
• Introduce and discuss some principles for HR-MS
discovery & association
• As we don’t have a ToC reference it is difficult to
produce specific text at this point
• However we could agree on some principles
Two dissimilar scenarios require HR-MS discovery:
• MS to MS Direct Communication with or without
infrastructure stations (MS-MS communications)
• (SRD 6.1.3.1)
• HR-MS Forwarding to Network (HR-MS
forwarding)
• (SRD 6.1.3.2)
• Above will likely be used in different
environments and for very different applications
Let’s compare:
Property
HR-MS Forwarding
MS-MS Communications
With / Without Infrastructure
Application example
Smart Grid
PPDR
Topology
Tree
Adhoc peer to peer in P2P or P2MP
configurations
Mobility
Low
Medium to High
Number of subscriber
stations
Very large compared to current
cellular
On par with current cellular or smaller
Network sharing
Yes – with non M2M devices
Yes (if infrastructure is present) / No
Battery consumption
Very low
On par with current cellular
Link duration
“Almost permanent”
Per call (avoid keeping n(n-1)/2 links)
Frequency of link creation
Very low (once?)
High
Link creation latency
requirement
Loose
Tight
BS can help?
Yes
Yes (if infrastructure present) / No
Observations
HR-MS forwarding
• Should minimize
interference
• Should minimize battery
consumption
• Speed of link creation not
as important
MS-MS Communications
• Should optimize speed of
link creation
• Interference and battery
consumption are not as
important
These differences result in different discovery and
association procedures for the two cases
Text proposal
• Section xxx HR-MS discovery for MS-MS
communications
The HR-MS discovery procedure and signals are
designed to optimize the speed of link creation.
• Section yyy HR-MS discovery for HR-MS
Forwarding
The HR-MS discovery procedure and signals are
designed to minimize interference and battery
consumption.
