This document outlines the 5G NR slot formats as defined in the 3GPP TS 38.200 series of standards. These formats define the allocation of symbols within a slot for downlink (D), uplink (U), and flexible (X) transmissions.

Here’s a visual representation of some 5G NR slot formats:

5G NR slot formats-1

5G NR slot formats-2

The tables above illustrate different combinations of downlink, uplink and flexible symbols that can be configured within a single slot.

Key to Symbols

The following abbreviations are used to describe the different symbol types:

  • D: Downlink Symbol
  • X: Flexible Symbol
  • U: Uplink Symbol
