-How to configure wireshark for dissecting LTE protocols:
+How to configure wireshark for dissecting LTE/NR protocols:
 - start the wireshark as a sudoers
   - goto analyze->enabled prototols
-  => enable mac_lte_udp and rlc_lte_udp
+  => enable mac_xxx_udp and rlc_xxx_udp (xxx is lte or nr)
   - goto edit/preferences and expand Protocols
   - select UDP and check "try heuristic sub-dissectors first"
-  - select MAC-LTE, and check all the options (checkboxes), and set the "which layer info to show in info column" to "MAC info"
-    - select RLC-LTE, and check all the options except the "May see RLC headers only", and
+  - select MAC-LTE (or MAC-NR), and check all the options (checkboxes), and set the "which layer info to show in info column" to "MAC info"
+  - select RLC-LTE (or NR), and check all the options except the "May see RLC headers only", and
     set the "call PDCP dissector for DRB PDUs" to "12-bit SN". Optionally you may select the sequence analysis for RLC AM/UM.
+  - select PDCP-LTE (or NR)
 
     How to use
     - start eNB or UE with option --opt.type wireshark
