What is a SIB in LTE?
System Information Blocks in LTE, SIBs carry relevant information for the UE, which helps UE to access a cell, perform cell re-selection, information related to INTRA-frequency, INTER-frequency, and INTER-RAT cell selections.
What is SIB9?
SIB9 contains information related to GPS time and Coordinated Universal Time (UTC). The UE may use the parameters provided in SIB9 to obtain the UTC, the GPS and the local time.
Which SIB used for Etws?
The SIBs that carry the information about ETWS is SIB10 and SIB11. When an emergency situation happens, network broadcast the details of the emergency via SIB 10/SIB11 and inform UE to let decode SIB10/11 by sending special Paging message.
What is 5G Pbch?
PBCH (Physical Broadcast Channel)
How are SIB transmitted?
SIBs are transmitted using BCCH mapped on DL-SCH which in turn mapped on PDSCH. System information will be changed every BCCH modification period. Signalling Tester model MD8430A from Anritsu can be used as LTE Base Station Emulator. This will emulate LTE MIBs and SIBs over corresponding LTE channels.
What is MIB in 5g?
MIB is mandatory system information that is broadcasted by the gNB at a set periodicity. During the initial cell selection procedure, UE assumes that the SSB is broadcasted every 20ms by the gNB. UE gets MIB by decoding the PBCH from the SS-PBCH block beam.
What is PSS and SSS in 5G?
Cell search is the procedure by which a UE acquires time and frequency synchronization with a cell and decode the Cell ID of that cell. In 5G NR, Cell search concept is similar to what it is in LTE in terms of decoding Primary Sync Signal (PSS) and Secondary Sync Signal (SSS) to the Physical Cell ID (PCI).
What is PSS & SSS?
Synchronization Signals and Determining Cell Identity The primary synchronization signal (PSS) is linked to the cell identity within the group ( N I D ( 2 ) ). The secondary synchronization signal (SSS) is linked to the cell identity group ( N I D ( 1 ) ) and the cell identity within the group ( N I D ( 2 ) ).
How many sibs are there in 3GPP?
System Information Block (SIB): There are 13 SIBs (SIB1 to SIB13) in the above 3GPP standard specification. Each SIB contains specific information. SIB1 means System Information Block Type1.
What is the largest SIB type number?
We first started with around 12 SIBs and now (as of Jan 2020. Release 15), the largest SIB Type number is SIB24. Followings are the whole SIB list as of now.
What is the difference between MIB and Sib in LTE and Nr?
In LTE (actually all other techology except NR), all the SIBs are broadcast periodically regardless of whether UE want it or not. However, in NR there are two different types of SIBs. like SIBs in LTE and the other type is the one being transmitted only when there is the request from UE. Overall MIB/SIB Transmission Flow
What are the 3GPP specifications?
3GPP specifications. The term “3GPP specification” covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA) and LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications.
