Paging Issue Check Points                          Some check points which will help you to analyze the root cause . Channel to Check :                     PCCH -> PCH -> PDSCH   Check points: RLC TM P-RNTI ->16bit (‭65534‬-> FFFE)-> Can be seen in PDCCH channel  Paging Message will go on DCI Format 1_0 always -> Can be seen in PDCCH channel DCI payload check (will update ASAP)  Timer T3513 5G-S-TMSI value from Registration Accept message ->fiveGGUTI-> last 6 Bytes  Spec 23.003  sec 2.11 PDCCH Transmission for paging can share the same search space as PDCCH transmission for SIB1 in case of Multiplexing pattern3->Can be seen in PDCCH channel  In SIB1 - > pagingSearchSpace == '0’  It mean that paging and SIB1 share the same search space Addition Information : Transmit Paging...

NR MIB

Case : UE Powered ON Cell Search (PSS and SSS) and PBCH decode to get MIB Decode and store the MIB -> we will focus more on MIB itself  check if cellBarred= barred,  stop here   cellBarred != barred, move to next to process further information Decode SIB1 using parameters provided by MIB and store the results As SIB1 indicate no demand SI, decode other System Information (SIBs) The MIB includes the system information transmitted on BCH(TE->UE).     -> RLC TM      -> BCCH -> BCH->PBCH      ->    the MIB is always transmitted on the BCH with a periodicity of 80 ms and repetitions made within 80 ms (TS 38.212 [17], clause 7.1) and it includes parameters that are needed to acquire SIB1 from the cell. The first transmission of the MIB is scheduled in subframes as defined in TS 38.213 [13], clause 4.1 and repetitions are scheduled according to the period of SSB ; As per Spec:38.331 MIB ::= ...
