Executive Summary The present document summarizes the CBTC and C-ITS recommendations for potential spectrum sharing of CBTC and C-ITS applicatio

20、ns. The present document identifies technical solutions for sharing as follows: Mitigation methods. Methods to detect a mitigation area. Introduction The present document has been developed in cooperation with TC ITS in order to present to the Electronic Communications Committee (ECC) of the Europea

21、n Conference of Post and Telecommunications Administrations (CEPT) a common point of view regarding sharing possibilities between CBTC and ITS applications in the 5 875 MHz to 5 925 MHz frequency band. After having clearly defined CBTC applications, the present document defines first the functional

22、needs of CBTC regarding its communication. From that, technical needs for the communication system are derived, and the scenarios where sharing the spectrum between CBTC application and ITS road applications could be an issue are described. Finally the different technical means of sharing bandwidth

23、are introduced and the next steps including a proposal for short term regulation are defined. ETSI ETSI TR 103 442 V1.1.1 (2016-05) 6 1 Scope The present document investigates the possibility of shared use of spectrum between CBTC and ITS applications in the 5 875 MHz to 5 925 MHz under the assumpti

24、on that CBTC applications have priority over ITS-G5 applications. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
