9.2 Scheduling information overhead reduction

25.3003GPPGeneral descriptionRelease 17Stage 2TSUniversal Terrestrial Radio Access Network (UTRAN)

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

To reduce the overhead of SIB scheduling information, included in MIB and Scheduling Blocks, the network may use mandatory default values for SIB_OFF and SEG_COUNT (when SIB_POS offset info is included) for SIBs of REL-12 or later.
