4 Synchronization procedures
4.1 Cell search
Cell search is the procedure for a UE to acquire time and frequency synchronization with a cell and to detect the
physical layer Cell ID of the cell.
A UE receives the following synchronization signals (SS) in order to perform cell search: the primary synchronization
signal (PSS) and secondary synchronization signal (SSS) as defined in [4, TS 38.211].
A UE assumes that reception occasions of a physical broadcast channel (PBCH), PSS, and SSS are in consecutive
symbols, as defined in [4, TS 38.211], and form a SS/PBCH block. The UE assumes that SSS, PBCH DM-RS, and
PBCH data have same EPRE. The UE may assume that the ratio of PSS EPRE to SSS EPRE in a SS/PBCH block is
either 0 dB or 3 dB. If the UE has not been provided dedicated higher layer parameters, the UE may assume that the
ratio of PDCCH DMRS EPRE to SSS EPRE is within -8 dB and 8 dB when the UE monitors PDCCHs for a DCI
format 1_0 with CRC scrambled by SI-RNTI, P-RNTI, or RA-RNTI, or for a DCI format 2_7, or for a DCI format 4_0.
For a half frame with SS/PBCH blocks, the first symbol indexes for candidate SS/PBCH blocks are determined
according to the SCS of SS/PBCH blocks as follows, where index 0 corresponds to the first symbol of the first slot in a
half-frame.
- Case A - 15 kHz SCS: the first symbols of the candidate SS/PBCH blocks have indexes of �2,8� +14 ⋅ �.
- For operation without shared spectrum channel access:
- For carrier frequencies smaller than or equal to 3 GHz, � =0,1.
- For carrier frequencies within FR1 larger than 3 GHz, � = 0,1,2,3.
- For operation with shared spectrum channel access, as described in [15, TS 37.213], � = 0,1,2,3,4.
� �
- Case B - 30 kHz SCS: the first symbols of the candidate SS/PBCH blocks have indexes 4,8,16,20 +28⋅ �.
For carrier frequencies smaller than or equal to 3 GHz, � =0. For carrier frequencies within FR1 larger than 3
GHz, � =0,1.
� �
- Case C - 30 kHz SCS: the first symbols of the candidate SS/PBCH blocks have indexes 2,8 +14 ⋅ �.
- For operation without shared spectrum channel access
- For paired spectrum operation
- For carrier frequencies smaller than or equal to 3 GHz, � =0,1. For carrier frequencies within FR1
larger than 3 GHz, � = 0,1,2,3.
- For unpaired spectrum operation
- For carrier frequencies smaller than 1.88 GHz, � =0,1. For carrier frequencies within FR1 equal to or
larger than 1.88 GHz, � = 0,1,2,3.
- For operation with shared spectrum channel access, � = 0,1,2,3,4,5,6,7,8,9.
� �
- Case D - 120 kHz SCS: the first symbols of the candidate SS/PBCH blocks have indexes 4,8,16,20 +28 ⋅ �.
For carrier frequencies within FR2, � = 0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18.
- Case E - 240 kHz SCS: the first symbols of the candidate SS/PBCH blocks have indexes
� �
8,12,16,20,32,36,40,44 +56⋅ �. For carrier frequencies within FR2-1, � = 0,1,2,3,5,6,7,8.
- Case F – 480 kHz SCS: the first symbols of the candidate SS/PBCH blocks have indexes �2, 9� +14⋅ �. For
carrier frequencies within FR2-2, � =
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31.
ETSI
3GPP TS 38.213 version 17.13.0 Release 17 11 ETSI TS 138 213 V17.13.0 (2025-07)
� �
- Case G – 960 kHz SCS: the first symbols of the candidate SS/PBCH blocks have indexes 2, 9 +14⋅ �. For
carrier frequencies within FR2-2, � =
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31.
From the above cases, if the SCS of SS/PBCH blocks is not provided by ssbSubcarrierSpacing, the applicable cases for
a cell depend on a respective frequency band, as provided in [8-1, TS 38.101-1], [8-2, TS 38.101-2] and [8-5, TS
38.101-5]. A same case applies for all SS/PBCH blocks on the cell. If a 30 kHz SS/PBCH block SCS is indicated by
ssbSubcarrierSpacing, Case B applies for frequency bands with only 15 kHz SS/PBCH block SCS as specified in [8-1,
TS 38.101-1] and [8-5, TS 38.101-5], and the case specified for 30 kHz SS/PBCH block SCS in [8-1, TS 38.101-1] and
[8-5, TS 38.101-5] applies for frequency bands with 30 kHz SS/PBCH block SCS or both 15 kHz and 30 kHz SS/PBCH
block SCS as specified in [8-1, TS 38.101-1] and [8-5, TS 38.101-5]. For a UE configured to operate with carrier
aggregation over a set of cells in a frequency band of FR2 or with frequency-contiguous carrier aggregation over a set
of cells in a frequency band of FR1, if the UE is provided SCS values by ssbSubcarrierSpacing for receptions of
SS/PBCH blocks on any cells from the set of cells, the UE expects the SCS values to be same.

� is determined according to SS/PBCH block patterns for Cases A through G. � is a maximum number of
��� ���
SS/PBCH block indexes in a cell, and the maximum number of transmitted SS/PBCH blocks within a half frame is

- For operation without shared spectrum channel access in FR1 and FR2, and for operation with shared spectrum

A UE can be provided per serving cell by ssb-periodicityServingCell a periodicity of the half frames for reception of the
SS/PBCH blocks for the serving cell. If the UE is not configured a periodicity of the half frames for receptions of the
SS/PBCH blocks, the UE assumes a periodicity of a half frame. A UE assumes that the periodicity is same for all
SS/PBCH blocks in the serving cell.
For initial cell selection, a UE may assume that half frames with SS/PBCH blocks occur with a periodicity of 2 frames.
For operation without shared spectrum channel access, an SS/PBCH block index is same as a candidate SS/PBCH block
index.
For operation with shared spectrum channel access, a UE assumes that transmission of SS/PBCH blocks in a half frame
is within a discovery burst transmission window that starts from the first symbol of the first slot in a half-frame. The UE
can be provided per serving cell by discoveryBurstWindowLength a duration of the discovery burst transmission
window. If discoveryBurstWindowLength is not provided, the UE assumes that the duration of the discovery burst
transmission window is a half frame. For a serving cell, the UE assumes that a periodicity of the discovery burst
transmission window is same as a periodicity of half frames for receptions of SS/PBCH blocks in the serving cell. The
UE assumes that one or more SS/PBCH blocks indicated by ssb-PositionsInBurst may be transmitted within the
discovery burst transmission window and have candidate SS/PBCH blocks indexes corresponding to SS/PBCH block
indexes provided by ssb-PositionsInBurst. If MSB �, � ≥1, of ssb-PositionsInBurst is set to 1, the UE assumes that
SS/PBCH block(s) within the discovery burst transmission window with candidate SS/PBCH block index(es)

corresponding to SS/PBCH block index equal to � −1 may be transmitted; if MSB � is set to 0, the UE assumes that
the SS/PBCH block(s) are not transmitted. If MSB �, � ≥1, of inOneGroup is set to 1, and MSB �, � ≥1, of
groupPresence is set to 1, the UE assumes that SS/PBCH block(s) within the discovery burst transmission window with
candidate SS/PBCH block index(es) corresponding to SS/PBCH block index determined by � and � may be
transmitted; otherwise, the UE assumes that the SS/PBCH block(s) are not transmitted.
For operation with shared spectrum channel access in FR1, a UE assumes that SS/PBCH blocks in a serving cell that are
within a same discovery burst transmission window or across discovery burst transmission windows are quasi co-
located with respect to average gain, quasi co-location 'typeA' and 'typeD' properties, when applicable [6, TS 38.214], if

a value of �� mod � � is same among the SS/PBCH blocks. � is an index of a DM-RS sequence
����� �����

transmitted in a PBCH of a corresponding SS/PBCH block, and � is either provided by ssb-PositionQCL or, if ssb-
���
PositionQCL is not provided, obtained from a MIB provided by a SS/PBCH block according to Table 4.1-1 with � <

����
24 [4, TS 38.211]. The UE can determine an SS/PBCH block index according to �� mod � �, or according to
����� ���
���
��̅ mod � � where �̅ is the candidate SS/PBCH block index. The UE assumes that within a discovery burst
���
���
transmission window, a number of transmitted SS/PBCH blocks on a serving cell is not larger than � and a number
���
of transmitted SS/PBCH blocks with a same SS/PBCH block index is not larger than one.

For operation with shared spectrum channel access in FR2-2, a UE assumes that SS/PBCH blocks in a serving cell that
are within a same discovery burst transmission window or across discovery burst transmission windows are quasi co-
located with respect to average gain, quasi co-location 'typeA' and 'typeD' properties, when applicable, if a value of

provided by ssb-PositionQCL or, if ssb-PositionQCL is not provided, obtained from a MIB provided by a SS/PBCH

block according to Table 4.1-2. The UE can determine an SS/PBCH block index according to ��̅ mod � �. The UE

assumes that within a discovery burst transmission window, a number of transmitted SS/PBCH blocks on a serving cell

For operation without shared spectrum channel access in FR2-2, a UE expects a MIB in a SS/PBCH block to provide
subCarrierSpacingCommon = 'scs30or120'.
Upon detection of a SS/PBCH block, the UE determines from MIB that a CORESET for Type0-PDCCH CSS set, as
described in clause 13, is present if � <24 [4, TS 38.211] for FR1 or if � <12 for FR2. The UE determines
��� ���
from MIB that a CORESET for Type0-PDCCH CSS set is not present if � >23 for FR1 or if � >11 for FR2;
��� ���
the CORESET for Type0-PDCCH CSS set may be provided by PDCCH-ConfigCommon.
For a serving cell without transmission of SS/PBCH blocks, a UE acquires time and frequency synchronization with the
serving cell based on receptions of SS/PBCH blocks on the PCell, or on the PSCell, or on an SCell if applicable as
described in [10, TS 38.133], of the cell group for the serving cell.

4.2 Transmission timing adjustments
A UE can be provided a value � of a timing advance offset for a serving cell by n-TimingAdvanceOffset for the
"#,$%%&’(
serving cell. If the UE is not provided n-TimingAdvanceOffset for a serving cell, the UE determines a default value
� of the timing advance offset for the serving cell as described in [10, TS 38.133].
"#,$%%&’(
If a UE is configured with two UL carriers for a serving cell, a same timing advance offset value � applies to
"#,$%%&’(
both carriers.
Upon reception of a timing advance command for a TAG, the UE adjusts uplink timing for PUSCH/SRS/PUCCH
transmission on all the serving cells in the TAG based on a value � that the UE expects to be same for all the
