3 Architectural Issues Discuss some concepts:
Need of an Interface notion Need of changes in the definition of Link Multicast Link_ID How do you work with an interface having several links MN centric view vs. peer-to-peer view

4 General Areas of Interest
Getting/Setting interface capabilities (local or remote) Media independent capacity definition Monitoring Capacity constrained HO

5 Getting Interface Capabilities
Define a Mechanism to obtain the capabilities of an interface, at MAC/PHY level Scheduling Deterministic vs. probabilistic Algorithm number of supported (hardware) queues native multicast or not forwarding behavior (ARQ vs. FEC, …) “QoS characteristics”? Supported tx levels, MCSs, channels, … Store this information in the MIIS

6 Setting Interface Capabilities
Primitives enabling the configuration of interfaces Supported tx levels, MCSs, channels, … Possibly power saving configuration (MRPM) Remote configuration of interfaces allow for fast reconfiguration in the network

7 Media Independent Capacity Metric
How do we know, in a media independent way, the remaining capacity of a wireless link? How can we define in the current specification that several stations are in the same capacity domain? Thus, we need a shared resource concept for

8 Monitoring Extend monitoring capabilities of 802.21
Currently uses media dependent monitoring, can this be done in a media independent way? Should we still use placeholder functions? Reuse/Adapt 3GPP (or other) templates for reporting measurements? Per-flow metering?

9 Resource-Constrained HO
considers the bottleneck to be in the access network (e.g. between AP and STA) What happens if the constraint is in the backhaul? Granularity problem: right now there is no way of working with several flows individually, need to HO the complete set of flows managed by a station
