2. Mobility Mobile Base Station –Should support the use of a node that is moving to assume the role of a base station. –Should operate at speeds of up to 100kmh ?? Mobile Relay Station –Should allow fast association to different base stations or relays. –Should operate at speeds of up to 100kmh ??

3. Mobility Scenarios RS MS Connectivity graph DATA path BSMSBSRS Scenario A Scenario B RS BS RS BS Scenario C.1Scenario C.2

4. RS sourcing and sinking of data + multihop RS should be allowed to source and sink data besides relaying data that do not belong to itself Should support more than 2 hops BS RS MS Connectivity graph DATA path

5. Direct communication BS RS MS Connectivity graph DATA path BS RS MS BS XX X INTERNET X

6. Relaying BS RS MS Connectivity graph RELAYING path BS RS MS BS XX X X INTERNET

7. Local Forwarding BS RS MS Connectivity graph DATA path BS RS MS BS X X

8. Multi-path routing BS RS MS Connectivity graph Alternative DATA path BS RS MS BS DATA path

9. Neighbor discovery 802.16n system should allow all SS and RS to discover other SS or RS within its two hop neighborhood
