Agenda item 1.12
1.12 to consider possible global or regional harmonized frequency bands, to the maximum extent possible, for the implementation of evolving Intelligent Transport Systems (ITS) under existing mobile-service allocations, in accordance with Resolution 237 (WRC-15);
Resolution 237 (WRC-15) – Intelligent Transport Systems applications invites WRC-19 based on the results of ITU-R studies, to consider possible global or regional harmonized frequency bands for the implementation of evolving ITS under existing mobile-service allocations.
Several ITU-R Reports and Recommendations have been developed in support of this agenda item.
ITU-R studies indicated that some administrations throughout the three Regions have designated the frequency band of 5 850-5 925 MHz, or parts thereof, for the deployment of ITS. Recommendation ITU R M.2121, "Harmonization of frequency bands for Intelligent Transport Systems in the mobile service" recommends that several frequency bands within each Region, in whole or in part, be used for current and future ITS applications.
Three methods have been proposed to satisfy this agenda item:
− Method A: No change to the Radio Regulations since ITS can operate within existing mobile service allocations and the required harmonization of frequencies for ITS can be achieved through ITU-R Recommendations and Reports.
− Method B: No change to the Table of Frequency Allocations in the Radio Regulations, and add a new WRC Resolution to encourage administrations to use 5 850-5 925 MHz, or parts thereof, as global harmonized evolving ITS frequency bands. Other harmonized frequency band(s) for evolving ITS applications refer to the most recent version of Recommendation ITU R M.2121..
− Method C: No change to the Table of Frequency Allocations in the Radio Regulations, and add a new WRC Resolution to encourage administrations to use globally and regionally harmonized frequency bands for ITS applications by referring to the most recent version of Recommendation ITU-R M.[ITS_FRQ].
For all Methods, Resolution 237 (WRC-15) should be suppressed.
Evolving ITS are being deployed to assist safe driving and to support transportation system efficiency and environmental sustainability. It is recognized that the frequency bands within existing mobile service allocations being used by evolving ITS may also be utilized by other applications and services.
Since 1995, research and development activities have been conducted in infocommunication systems as core technologies of ITS. ITS, including legacy ITS, systems have been deployed in some countries. Evolving ITS, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-network (V2N) and vehicle-to-pedestrian (V2P) communications have been deployed in some countries to assist with safer driving. Communicating with moving vehicles is one of the typical use cases for radiocommunications, and a variety of ITS applications rely on radiocommunication technologies including the next generation of ITS applications.
Evolving ITS also become important in helping to reduce road traffic problems such as congestion and accidents. To address road safety and efficiency-related matters, the ITS with vehicle-to-everything communication (e.g. WAVE, ETSI ITS-G5, LTE based V2X, ITS Connect) are studied in ITU-R.
CEPT is of the view that its existing regional harmonisation measures for ITS in the band 5 855-5 925 MHz are sufficient and no changes to the RR are required in response to WRC-19 Agenda item 1.12 except the suppression of Resolution 237 (WRC-15). CEPT is developing a revision of its existing harmonisation framework for ITS around 63-64 GHz.
Ireland as a member of the CEPT supports Method A. An ITU-R Recommendation, which is not referenced in the Radio Regulations, is considered sufficient to harmonize frequency bands for ITS pertaining to the exchange of information to improve traffic management and assisting safe driving.
