Specifically, in some territories such as the European Union the cross-border corridors have relevance, as they are the cohesive paths for terrestrial transport. Therefore, 5G for CAM applications is planned to be deployed there first. However, cross-border contexts imply paramount communication challenges, such as seamless roaming, not addressed by current technology. This paper identifies relevant future 5G enhancements, specifically those specified by Third-Generation Partnership Project (3GPP) releases beyond Release 15, and outlines how they will support the ambitions of highly automated driving in cross-border corridors. In order to conduct this study, a set of representative use cases and the related communication requirements were identified. Then, for each use case, the most relevant 5G features were proposed. Some open issues are described at the end.<\/jats:p>","DOI":"10.3390\/s20226622","type":"journal-article","created":{"date-parts":[[2020,11,19]],"date-time":"2020-11-19T06:23:52Z","timestamp":1605767032000},"page":"6622","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["5G Beyond 3GPP Release 15 for Connected Automated Mobility in Cross-Border Contexts"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8367-2413","authenticated-orcid":false,"given":"Gorka","family":"Velez","sequence":"first","affiliation":[{"name":"Vicomtech Foundation, Basque Research and Technology Alliance (BRTA), Mikeletegi 57, 20009 Donostia-San Sebasti\u00e1n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1213-6787","authenticated-orcid":false,"given":"\u00c1ngel","family":"Mart\u00edn","sequence":"additional","affiliation":[{"name":"Vicomtech Foundation, Basque Research and Technology Alliance (BRTA), Mikeletegi 57, 20009 Donostia-San Sebasti\u00e1n, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giancarlo","family":"Pastor","sequence":"additional","affiliation":[{"name":"Department of Communications &amp; Networking, Aalto University School of Electrical Engineering, P.O.
