Flexible slot format means flexible resource allocation in many possible ways. It could mean:

  • TDD self contained slot where opportunity for DL or UL scheduling, DL or UL data, and acknowledgement or SRS are all in the same slot.
  • Data centric slot where DL or UL scheduling in few symbols followed by DL or UL data in the rest.

  • Mini slot where 2, 4 or 7 symbols are used for URLLC type traffic

  • Blank slot for future use cases

Slot Format Indication (SFI) is used to indicate details of the slot (DCI/RRC is used to convey)
