The set command is used to activate or deactivate the UE test mode according to UE test mode procedures as defined in TS 36.509 clause 5.3.2 and clause 5.3.3 for V2X over E-UTRA PC5, and in TS 38.509 clause 5.2.2 and clause 5.2.3 for V2X over NR PC5. When <status>=1, the set command activates the UE test mode and sets the UE in test loop mode. The parameter <test_loop_mode> must be included to indicate the UE test loop mode. When <status>=0, the set command deactivates the UE test mode. Refer clause 9.2 for possible <err> values. The read command returns the current UE test mode activation and UE test loop mode statuses. The test command returns values supported as compound values.

<status> <test_loop_mode>

Optional.

The set command is used to close or open the UE test loop mode E according to UE test loop procedures as defined in TS 36.509 clause 5.4.2, clause 5.4.4c and clause 5.4.5 for V2X over E-UTRA PC5, and in 3GPP TS 38.509 [178] clause 5.3.2, clause 5.3.3 and clause 5.3.4.3. The AT command is only applicable when test mode is activated, see clause 15.2. The <status> indicates whether the UE test loop mode E is closed or opened. If <status>=0, the parameters <direction>, <format>, <length> and <monitor_list> are as required provided to configure UE test loop mode E. The UE test loop mode E provides means for either transmitting or receiving of V2X communication packets, and the <direction> indicates the direction of communication under test. For communication receive operation, <direction>=0 and the UE test loop mode E provides counting of successfully received STCH PDCP SDUs for V2X over E-UTRA PC5 or STCH SDAP SDUs for V2X over NR PC5, PSCCH transport blocks and PSSCH transport blocks. The parameters <format>, <length> and <monitor_list> must be provided. For communication transmit operation, <direction>=1 and the UE test loop mode E provides trigger for transmission of IP packets for V2X communication message on STCH. The parameters <format>, <length> and <monitor_list> are not used and ignored if received. The parameter <sl_mimo> indicates the number of spatial layer(s) used for NR PSSCH transmission for UE which supports SL MIMO, and is not used and ignored if UE doesn't support SL MIMO. All parameters are discarded when <status>=1 or when the UE test mode is deactivated. The read command returns the current settings. The test command returns values supported as compound values.

<status> <direction> <format> <length> <monitor_list> <sl_mimo>

Optional.

The set command is used to request the UE to report the counter of successful reception of sidelink PSCCH transport blocks, STCH PDCP SDU packets and PSSCH transport blocks according to the ProSe Packet Counter reporting procedure as defined in 3GPP TS 36.509 [142] clause 5.7 for ProSe or V2X over E-UTRA PC5 and/or sidelink PSCCH transport blocks, STCH SDAP SDU packets and/or PSSCH transport blocks according to the ProSe Packet Counter reporting procedure as defined in 3GPP TS 38.509 [178] clause 5.9 for V2X over NR PC5. The AT command is only applicable when test mode is activated, see clause 15.2. Refer to clause 9.2 for possible <err> values.

<type1> <type2> <type3> <format> <length1> <length2> <length3> <counter1> <counter2> <counter3>

Optional.

The set command is used to reset the current UTC time that has been calculated from GNSS in the UE as defined in 3GPP TS 36.509 [142] clause 5.5.3. This allows the UE to rapidly reaquire GNSS and calculate a new value of UTC time. The UE can optionally retain the information that may aid rapid reaquisition of GNSS and the calculation of a new value of UTC time. The AT command is only applicable when test mode is activated, see clause 15.2. Refer to clause 9.2 for possible <err> values.

None.

Optional.

The execution command is used to request the UE to report the Channel busy ratio (CBR) for V2X communication over E-UTRA PC5 measured as specified in clause 5.1.30 of TS 36.214 or over NR PC5 measured as specified in clause 5.1.27 of TS 38.215. The AT command is only applicable when test mode is activated, see clause 15.2. Refer to clause 9.2 for possible <err> values.

<PC5_type> <cbr-pssch> <cbr-pscch> <nr-cbr>

Optional.

The set command is used to trigger the UE to start or stop sending V2X data over PC5 as defined in clause 14 of TS 36.213. The AT command is only applicable when test mode is activated, see clause 15.2. The <action> indicates whether the UE shall start or stop sending data. If <action>=1, the parameters <data_size> and <periodicity> must be provided. All parameters are discarded when <action>=0 or when the UE test mode is deactivated. The read command returns the current settings. The test command returns values supported as compound values.

<action> <data_size> <periodicity> <pc5_type>

Optional.

The execution command is used to request the UE to send the UEAssistanceInformation message to request SPS grant from eNB as specified in clause 5.6.10.2 of TS 36.331 or from gNB as specified in clause 5.7.4.2 of TS 38.331. The set command is only applicable when test mode is activated, see clause 15.2. When <interface>=0, the UE shall send the UEAssistanceInformation message to request UL SPS grant for V2X communication over LTE-Uu from eNB. When <interface>=1, the UE shall send the UEAssistanceInformation message to request SL SPS grant for V2X communication over E-UTRA PC5 from eNB. When <interface>=2, the UE shall send the UEAssistanceInformation message to request UL SPS grant for V2X communication over NR-Uu from gNB. When <interface>=1, the UE shall send the UEAssistanceInformation message to request SL SPS grant for V2X communication over NR PC5 from gNB. Refer to clause 9.2 for possible <err> values. Test command returns the values supported as a compound value.

<interface>

Optional.
