Toward 5G RAN virtualization by Intel and Astri http://astri.oeg Flexible architecture Modular PHY processing architectures PDCP Split MAC/PHY Split - HARQ processing in RRU(How???) Lower PHY Split - High FB overhead but smallest packet latency. Good for JT and JR for COMP Good for Massive MIMO and Ultra low-latency communication(Why?) FAPI based MAC/PHY communication L1 adaptation layer for MAC/PHY split (and Lower PHY Split?) MAC/PHY split in one CPU MAC/PHY split in one machine but netrwork based MAC/PHY communication over OVS Virtual Cell A group of physical cells form a Virtual Cell which does not require HO between the physical cells.
