Frame Structure Comparison: 4G & 5G

Hi All.

The following summarized the main differences between 4G & 5G Frame Structure.

  1. Frame and Subframe duration remained the Same for 5G.

  2. The number of Symbols in a slot is now fixed to 14 in 5G (4G is fixed to 7).

  3. 5G has a flexible numerology, which allows different configurations as the Slot Duration relies on SCS (duration = 1 /SCS).

  4. 5G is now using a Slot as a scheduling Unit instead of a Sub-frame compared to 4G.

  5. NR RB Resource Grid is double 4G(14 vs. 7 OFDM symbols in one RB).
