3 Introduction Problems – Explosive growth in mobile data demand Studies by Cisco suggest 66x growth in mobile internet traffic, from – Flattering revenues for network operators From voice centric (“minutes of use”) to data centric (“flat-rate”) Hierarchical Networks (HN) for the solution – Single RAT HN – Multi-RAT HN Benefits of Hierarchical Networks – Cost/bit capacity enhancements – Client QoS, Coverage etc. are enhanced srho

4 Single RAT HN Multi-tier Networks – Increases areal capacity (bps/Hz/square meters) Client Tier – Reduces power consumption and interference to a neighbor cell 4 In-band Client cooperation (In-band CC) srho

5 Multi-RAT HN Virtual Carrier – A Multi-RAT device can communicate IEEE BS through IEEE AP Multi-RAT CC (Client Cooperation) – Enhanced Tethering srho

6 Technical Requirements for the HN Enhanced coordination between devices, between cells in the same tier and multi-tiers Enhanced interference mitigation Enhanced spectrum utilization Seamless mobility of connection flows among Multi- RATs – E.g. selective data offloading, handover Enhanced interworking with other RAT – E.g. IEEE AP ↔ IEEE BS Collaboration between Multi-RAT devices srho

7 BS-AP Interworking Example of interworking IEEE BS and IEEE AP 7 IEEE BS and an IEEE AP interaction – IEEE BS manages or coordinates the IEEE APs under its coverage. – Can provide low- access latency and enhanced networking srho

8 Multi-RAT HN Architecture AMS: Advanced Mobile Station ABS: Advanced Base Station 8 Virtual carrier & BS-AP interworking Multi-RAT CC srho
