3GPP RAN2 #133bis: 6G Control Plane Starts to Narrow Around Simpler SI, Paging and Mobility
3GPP RAN2 #133bis showed 6G RAN2 moving toward simpler system information, single paging, cleaner mobility and unified energy-saving behavior.

Technical recap of 3GPP RAN3 #131-bis in Malta, covering Release 20 progress on 6G RAN architecture, P2P vs SBI for the RAN-CN interface, 6G data collection, HLS, Xa, and NR ISAC architecture and procedures.
TSG RAN#111 in Fukuoka marked a turning point for 6G. As TR 38.914 neared completion, RAN shifted from vision to engineering—resolving key debates, aligning Release 21, and advancing AI/ML, ISAC, NTN, and Ambient IoT into concrete standardization paths.
RAN3 #130 was dominated by R-19 “essential corrections” work: LTM/mobility cleanups, Continuous MDT hooks, and AI/ML-for-NG-RAN alignment across Xn/F1/E1 and Stage-2 text. AIoT and energy saving also advanced via targeted NGAP/XnAP/F1AP fixes, while 6G study items stayed in architecture framing.
Deep technical wrap from 3GPP RAN2#131bis (Prague, 13–17 Oct 2025): Release-19 features converge—LP-WUS, NES, XR, Ambient IoT, sidelink multi-hop, NTN IoT—plus clear 6G mobility direction (standalone-first, unified HO/measurements). Every item traced to R2/RP docs.
RAN3 #129-bis: WG3’s 6G kickoff (RAN–CN interface options, lean-standards principle) plus concrete NG-RAN updates—AQP averaging window, UE-metrics alignment, C-MDT on Xn, LTM/inter-CU—and a reply to IETF TEAS.
