Specifically this work looks at a segment of the C\u2010RAN architecture called the fronthaul network. The fronthaul network required for network slicing needs to be able to dynamically assign capacity where it is needed. Deploying a fronthaul network faces a trade\u2010off between fronthaul bitrate, flexibility, and complexity of the local equipment close to the user. This work relates the challenges currently faced in C\u2010RAN research to the network requirements in network slicing. It also shows how using a packet\u2010switched fronthaul for network slicing will bring great advantages and enable the use of different functional splits, while the price to pay is a minor decrease in fronthaul length due to latency constraints.<\/jats:p>","DOI":"10.1155\/2018\/4860212","type":"journal-article","created":{"date-parts":[[2018,8,29]],"date-time":"2018-08-29T12:33:52Z","timestamp":1535546032000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Fronthaul for Cloud\u2010RAN Enabling Network Slicing in 5G Mobile Networks"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6402-5851","authenticated-orcid":false,"given":"Line M.
