|The European Telecommunications Standards Institute (ETSI) standardization in Europe has developed two technical reports on coexistence between Dedicated Short-Range Communications (called Intelligent Transportation Systems-G5 in Europe) and Long-Term Evolution-V2X.
One report describes a framework for sharing available spectrum at 5.9 GHz by prioritizing different technologies on frequency channels. The other technical report has elaborated on cochannel coexistence among technologies on the same channel in the same geographical area. The latter contains suggestions for techniques that have been scrutinized through simulations.
There are promising methods allowing both technologies to share resources. The technical reports will be publicly available at ETSI’s homepage for download when this column is published. The official names of the reports are ETSI TR 103 667 and ETSI TR 103 766.
