scope:

The present document proposes methods to ensure co-channel coexistence in the frequency range 5 915 MHz to 5 925 MHz where Urban Rail is the priority application.

In the present document, tramways are considered to be Road ITS because they are not segregated from road or pedestrian traffic.

NOTE 1: In the present document, no specific sharing methods for the operation of Urban Rail equipment in the Road ITS bands are considered given that Urban Rail equipment is not operating in these bands in areas where ITS equipment is active.

NOTE 2: The sharing techniques described in the present document are applicable to other frequency bands, if required to protect legacy CBTC systems (example: Malaga CBTC system uses the 5 905 MHz to 5 925 MHz band).
