2. World Class Standards STF395 2 STF 395 scope  Decentralised congestion control (DCC)  Following DCC methods were developed: Transmit power control (TPC) per packet, Transmit rate control (TRC), Transmit data rate control (TDC), and Receiver sensitivity control (RSC).  Coexistence between CEN DSRC and ITS-G5  Power levels to ensure coexistence were evaluated  Mitigation methods were developed

4. World Class Standards STF 395 4 Documents produced by STF 395  ETSI TS 102 687  Intelligent Transport Systems (ITS); Decentralized Congestion Control Mechanisms for Intelligent Transport Systems operating in the 5 GHz range; Access layer part  ETSI TS 102 792  Intelligent Transport Systems (ITS); Mitigation techniques to avoid interference between European CEN Dedicated Short Range Communication (CEN DSRC) equipment and Intelligent Transport Systems (ITS) operating in the 5 GHz frequency range

5. World Class Standards STF 395 5 Further ongoing work  DCC  A first draft for DCC in the networking & transport layer was presented at the last ITS WG3 meeting in TS 102 636-4-2.  The work on DCC in the facility layer just started.  The management components of DCC were proposed in TS 102 687 but no further work started yet.  Coexistence  Coexistence PlugTest at JRC in Ispra.  Supporting document: ETSI TR 102 960 test specification and results of the coexistence PlugTest
