[TS 38.331, clause 5.8.12]

When the UE selects GNSS as the synchronization reference source, the DFN, the subframe number within a frame and slot number within a frame used for NR sidelink communication are derived from the current UTC time, by the following formulae:

DFN= Floor (0.1*(Tcurrent –Tref–OffsetDFN)) mod 1024

SubframeNumber= Floor (Tcurrent –Tref–OffsetDFN) mod 10

SlotNumber= Floor ((Tcurrent –Tref–OffsetDFN)*2μ) mod (10*2μ)

Where:

Tcurrent is the current UTC time obtained from GNSS. This value is expressed in milliseconds;

Tref is the reference UTC time 00:00:00 on Gregorian calendar date 1 January, 1900 (midnight between Thursday, December 31, 1899 and Friday, January 1, 1900). This value is expressed in milliseconds;

OffsetDFN is the value sl-OffsetDFN if configured, otherwise it is zero. This value is expressed in milliseconds.

μ=0/1/2/3 corresponding to the 15/30/60/120 kHz of SCS for SL, respectively.

NOTE 1: In case of leap second change event, how UE obtains the scheduled time of leap second change to adjust Tcurrent correspondingly is left to UE implementation. How UE handles to avoid the sudden discontinuity of DFN is left to UE implementation.

NOTE 2: Void.

12.2.2.2.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 38.331 [22], subclause 5.8.2. Unless otherwise stated these are Rel-16 requirements.

[TS 38.331, clause 5.8.2]

The UE shall perform NR sidelink communication operation only if the conditions defined in this clause are met:

1> if the UE’s serving cell is suitable (RRC_IDLE or RRC_INACTIVE or RRC_CONNECTED); and if either the selected cell on the frequency used for NR sidelink communication operation belongs to the registered or equivalent PLMN as specified in TS 24.587 [57] or the UE is out of coverage on the frequency used for NR sidelink communication operation as defined in TS 38.304 [20] and TS 36.304 [27]; or

…

1> if the UE has no serving cell (RRC_IDLE);

[TS 38.331, clause 5.8.5.1]

Figure 5.8.5.1-1: Synchronisation information transmission for NR sidelink communication, in (partial) coverage

Figure 5.8.5.1-2: Synchronisation information transmission for NR sidelink communication, out of coverage

The purpose of this procedure is to provide synchronisation information to a UE.

[TS 38.331, clause 5.8.5.2]

A UE capable of NR sidelink communication and SLSS/PSBCH transmission shall, when transmitting NR sidelink communication, and if the conditions for NR sidelink communication operation are met and when the following conditions are met:

…

1> if out of coverage on the frequency used for NR sidelink communication, and the frequency used to transmit NR sidelink communication is included in sl-FreqInfoToAddModList in sl-ConfigDedicatedNR within RRCReconfiguration message or included in sl-FreqInfoList within SIB12; and has selected GNSS or the cell as synchronization reference as defined in 5.8.6.3:

2> if in RRC_CONNECTED; and if networkControlledSyncTx is configured and set to on; or

2> if networkControlledSyncTx is not configured; and for the concerned frequency syncTxThreshIC is configured; and the RSRP measurement of the reference cell, selected as defined in 5.8.6.3, for NR sidelink communication transmission is below the value of syncTxThreshIC:

3> transmit sidelink SSB on the frequency used for NR sidelink communication in accordance with 5.8.5.3 and TS 38.211 [16], including the transmission of SLSS as specified in 5.8.5.3 and transmission of MasterInformationBlockSidelink as specified in 5.8.9.4.3;

1> else:

2> for the frequency used for NR sidelink communication, if syncTxThreshOoC is included in SidelinkPreconfigNR; and the UE is not directly synchronized to GNSS, and the UE has no selected SyncRef UE or the PSBCH-RSRP measurement result of the selected SyncRef UE is below the value of syncTxThreshOoC; or

…

3> transmit sidelink SSB on the frequency used for NR sidelink communication in accordance with TS 38.211 [16] , including the transmission of SLSS as specified in 5.8.5.3 and transmission of MasterInformationBlockSidelink as specified in 5.8.9.4.3;

12.2.2.2.3 Test description

12.2.2.2.3.1 Pre-test conditions

System Simulator:

– NR Cell

– NR Cell 1 is the serving cell.

– System information combination NR-14 as defined in TS 38.508-1 [4] clause 4.4.3.1.2 is used in NR cell 1.

– NR-SS-UE

– NR-SS-UE 1 operating as NR sidelink communication device on the resources (i.e. the frequency included in pre-configuration) that UE is expected to use for transmission and reception via PC5 interface.

– NR-SS-UE 1 transmits S-SSB with SLSSID = 0, inCoverage = true in slots determined by sl-SSB-TimeAllocation1 and NR Cell 1 timing.

UE:

– UE is authorised to perform NR sidelink communication.

– The UE is equipped with below information in UE or in a USIM containing default values (as per TS 38.508-1 [4]) except for those listed in Table 12.2.2.2.3.1-1.
