  2. Abstract • In this slide set, we review the possible coexistence topologies and its according possible system architectures • We also point out some information to be considered while decision making Junho Jo/Jihyun Lee, LG Electronics

  3. Introduction • Logical entities • CDIS (Coexistence Discovery and Information Server) • Collect, aggregate and provide information facilitating coexistence • CM (Coexistence Manager) • Decision making • Possible topologies • Centralized • Super(Master) CM • Distributed • Information exchange between CMs • Autonomous Junho Jo/Jihyun Lee, LG Electronics

  4. Centralized Topology • CDIS • Mainly for data storage, data processing, etc. • CM • Super(Master) CM serves all the neighboring networks • One of the TVBD within interfering networks could be a Super(Master) CM Decision maker CM CDIS Decision maker CE CM CDIS CE CE Junho Jo/Jihyun Lee, LG Electronics

  5. Distributed Topology • CDIS • Facilitate opening interfaces between CMs • CM • Exchange information required for coexistence • Hierarchical and/or peer-to-peer decision making CDIS Decision maker CM Interface between CMs Interface B3[2] CM Decision maker Junho Jo/Jihyun Lee, LG Electronics

  6. Decision Making Algorithm • System requirement R5, R6 and R7 in [2] • 802.19.1 system • Shall analyze obtained information • Shall be capable of making coexistence decisions • Shall support different topologies • Information may include, regardless the topology, • Bandwidth of each TVWS network/device • Available channel list seen from each TVWS network/device and its according power constraint on each TVWS channel • Others such as regulatory classes, system parameters, neighborhood information analyzed in advance and so on Junho Jo/Jihyun Lee, LG Electronics
