Design of Flexible Fronthaul Featuring Per-UE Granularity and RU-Level Puncturing for URLLC Applications

摘要

We propose and experimentally verify a fine-grained, Per-UE, flexible fronthaul where different applications are transported over different function splits (i.e., URLLC over A-RoF-based fronthaul, Option-9, and other traffic over Option-7), exploiting two RU-level puncturing methods.
