5G/NR - MIB /

SIB

5G MIB / SIB in a
Nutshell

 The most important signal that UE has to detect before trying connection in NR SA a
and SIB1.

 The minimum requirement for UE to camp on a cell is to decode MIB and SIB1

 MIB is carried by the physical channel PBCH. PBCH is a part of a SSB

 SIB1 is carried by the physical channel PDSCH

 MIB carries information about reference subcarrier spacing, control channel for SIB P
DMRS position etc

 SIB1 carries all the basic informations for UE to perform the initial attachment proce
least upto RrcSetup

 SIB1 also carries scheduling information for other SIBs

 There are 21 SIBs defined in 3GPP (the number may increase as 3GPP release evolv

5G MIB / SIB in
Detail

Overall
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.

Interpretation of
this value varies
with frequency
range as
summarized in
the following
table.

FR1

FR2

ssb-
subcarrierOffset
: This
corresponds
to k_ssb(38.213)
. Indicates the
frequency
domain offset
between SSB
and the overall
resource block
grid in number
of subcarriers. If
k_ssb requires
the value higher
than 15, it is
represented by
the combination
of a PBCH data
field and ssb-
subcarrierOffset.

NOTE : In later
spec 38.331, I
see some
additional tricks
that this IE can
play with as
quoted below.

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

dmrs-TypeA-
Position :
Indicates
Position of (first)
DL DM-RS.

pdcchConfigSIB1
: Determines a
bandwidth for
PDCCH/SIB, a
common
ControlResource
Set (CORESET),
a common
search space
and necessary
PDCCH
parameters. This
corresponds
to RMSI-PDCCH-
Config.

NOTE : How
many bits are
required for
BCCH/MIB ?

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,

messageClass
Extension
SEQUENCE {}

As you see here,

BCCH-BCH is
made of one
choice
parameter which
has two
elements (MIB or
messageClassEx
tension). 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 =
messageClassEx
tension + 1

At least in the
latest spec
(38.331 f03),
messageClassEx
tension 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 {

systemFrame
Number
BIT STRING
(SIZE (6)), => 6
bits

subCarrierSpa
cingCommon
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

intraFreqResel
ection
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
