1、1 White Paper on ITS spectrum utilization in the Asia Pacific Region 2 White Paper www.5GAA.org White paper on ITS spectrum utilization in the Asia Pacific Region Executive Summary With the booming development of intelligent transportation systems (ITS), an increasing number of regulators and govern

2、ments around the globe pay attention to both technology and spectrum matters around ITS. This white paper summarizes the status of ITS spectrum utilization in the Asia Pacific Region, with focus on Japan, Korea, Singapore, Australia and China. Based on the ITS developments in the region, including b

3、usiness development, spectrum allocation and policy, the white paper provides recommendations on the choice of technology for ITS. The white paper also provides recommendations on the spectrum allocated for ITS applications based on direct vehicle-to-everything (V2X) communications. 5.9 GHz is the m

4、ost promising band used for ITS applications in Korea, Singapore, Australia and China. 5.9 GHz spectrum has been assigned for ITS deployments or ITS trials. Especially the 5855-5925 MHz band is defined as Band 47 in 3GPP, which is used for V2X operation over the PC5 interface. As it is beneficial to

5、 take advantage of the existing ecosystem development, it is highly recommended to consider 5.9 GHz as the target ITS spectrum for regulators and governments planning to allocate spectrum for ITS applications. Cellular-V2X (C-V2X), including its existing implementation of LTE-V2X as well as future r

6、ealizations, is considered as the desirable choice of technology for ITS. C-V2X, consisting of the Uu interface and the PC5 interface, provides the required performance for ITS applications both from the communication range and reliability perspectives according to extensive link-level and system-le
