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 Screenshot-2018-07-15-20.56.12

Virtual Cell

  • A group of physical cells form a Virtual Cell which does not require HO between the physical cells.
