5G MIB / SIB in DetailOverall functionality and structure of MIB / SIB of NR is almost same as LTE, but there is one major differeces between NR and LTE. 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. One type is the one being transmitted periodically 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 FlowOverall MIB / SIB transmission and relationships among SIBs is illustrated as below (38.331 - 5.2 System information)
MIB/SIB Aquisition ProcessMIB / SIB acquisition process would vary depending on cases. I will describe the overall MIB/SIB acquisition process with various cases. i) Power On ii) Search Cell and Decode MIB iii) Store the decoded MIB iv) Check if CellBarred = barred, stop there and if not, move to next step. v) Using the parameters in MIB, try decoding SIB1. vi) [if SIB1 decoding is successful] store the infromation and then move to next step. vii) [assuming that SIB1 indicate No On-Demand SI] Decode Other SIBs (SI)

See 38.331-5.2.1 and 38.213-4.1 for further details of MIB scheduling.
MIB ::= SEQUENCE { systemFrameNumber BIT STRING (SIZE (6)), subCarrierSpacingCommon ENUMERATED {scs15or60, scs30or120}, ssb-SubcarrierOffset INTEGER (0..15), dmrs-TypeA-Position ENUMERATED {pos2, pos3}, pdcch-ConfigSIB1 INTEGER (0..255), cellBarred ENUMERATED {barred, notBarred}, intraFreqReselection ENUMERATED {allowed, notAllowed}, spare BIT STRING (SIZE (1)) }
Corresponds to kSSB (see TS 38.213), which is the frequency domain offset between SSB and the overall resource block grid in number of subcarriers. (See TS 38.211, clause 7.4.3.1). For operation with shared spectrum channel access (see 37.213), this field corresponds to SSB, and kSSB is obtained from SSB (see TS 38.211, clause 7.4.3.1); the LSB of this field is used also for deriving the QCL relation between SS/PBCH blocks as specified in TS 38.213, clause 4.1. The value range of this field may be extended by an additional most significant bit encoded within PBCH as specified in TS 38.213.This field may indicate that this cell does not provide SIB1 and that there is hence no CORESET#0 configured in MIB (see TS 38.213, clause 13). In this case, the field pdcch-ConfigSIB1 may indicate the frequency positions where the UE may (not) find a SS/PBCH with a control resource set and search space for SIB1 (see TS 38.213 , clause 13). ==> On first look at the 38.213 it was not clear to me on how network can configure this value to let UE not to try to decode SIB1, but during the discussion with Frank, I got following description from 38.213 section 13.
If a UE detects a SS/PBCH block and determines that a CORESET for Type0-PDCCH CSS set is not present, and for k_SSB = 31 for FR1 or for k_SSB = 15 for FR2 In many cases, we are using PBCH and MIB interchangeably.. but you would know that they are not exactly same. PBCH is the name of the channel that carries MIB in it. Simply put, PBCH is a kind of container and MIB is the contents of the container. So you may easily guess that the size of PBCH (the container) would be at least the same or larger than the size of MIB(the contents). In order to clarify on this, you should look at the ASN structure of BCCH for MIB transmission. It is defined as follows.
BCCH-BCH-Message ::= SEQUENCE { message BCCH-BCH-MessageType }
BCCH-BCH-MessageType ::= CHOICE { mib MIB, messageClassExtension SEQUENCE {} } As you see here, BCCH-BCH is made of one choice parameter which has two elements (MIB or messageClassExtension). So this choice parameter requires 1 bit. As a result, BCCH-BCH bit length can be one of the followings : i) bit length of BCCH-BCH = bit length of mib + 1 ii) bit length of BCCH-BCH = messageClassExtension + 1 At least in the latest spec (38.331 f03), messageClassExtension is not defined. So let's think of case 1. To calculate the case 1, let's figure out the bit length of mib message. It can be counted as follows. MIB ::= SEQUENCE { systemFrameNumber BIT STRING (SIZE (6)), => 6 bits subCarrierSpacingCommon ENUMERATED {scs15or60, scs30or120}, => 1 bit ssb-SubcarrierOffset INTEGER (0..15), => 4 bits dmrs-TypeA-Position ENUMERATED {pos2, pos3}, => 1 bit pdcch-ConfigSIB1 INTEGER (0..255), => 8 bits cellBarred ENUMERATED {barred, notBarred}, => 1 bit intraFreqReselection ENUMERATED {allowed, notAllowed}, => 1 bit spare BIT STRING (SIZE (1)) => 1 bit } If you sum up all the number in red, you would get 23 bits. It means the size of MIB is 23 bits. Therefore, the size of BCCH-BCH = 23 + 1 = 24 bit. This 24 bit is the input data (A) of PBCH transport channel Process SystemInformationBlockType1Followings are the overall characteristics of SIB1 (SystemInformationBlockType1)
