Tx Configuration is based on TS 38 521-1 V17.4.1 (2022-07).
You can manually set four parameters via GUI or SCPI (see below) while others are Internally Set Parameters.
|
GUI Parameter |
Choices |
|---|---|
|
Bandwidth |
FR1 10MHz* FR1 20MHz FR1 30MHz FR1 40MHz |
|
Subcarrier Spacing |
15 kHz* 30 kHz 60 kHz |
|
RB Location |
Outer_Full* Outer_10RB_Left Outer_10RB_Right Inner_Full |
|
Modulation |
QPSK* 16QAM 64QAM 256QAM |
* default selection
|
SCPI Command |
[:SOURce]:RADio:NV2X:WAVeform[:ARB]:CCARrier<carrier>:CONFig:TX "Bandwidth: FR1BW10M|FR1BW20M|FR1BW30M|FR1BW40M, |
|
SCPI Example |
RAD:NV2X:WAV:CCAR0:CONF:TX " Bandwidth: FR1BW20M ,SubcarrierSpacing: SCS30K, RBLocation: OUTF , Modulation: QPSK " |
|
Couplings |
Parameters and default values of TX Config are list below: Bandwidth: FR1BW10M SubcarrierSpacing: SCS30K RBLocation: OUTF Modulation: QPSK One combined string is required to be input into the SCPI command. The format is "name: value , name: value …" . Default value will be used if parameter is not provided, or is not valid. The order of parameters does not matter. Parameter's name and value are case sensitive. |

|
Beta offset for 2nd stage SCI |
different value defined in spec |
Beta Offset Index: value is taken from Table 9.3-2 below, which appears in TS 38 213 V16.10.0 9.3-2 |
Table 9.3-2: Mapping of beta_offset values for CSI and the index signaled by higher layers
Refer to the partial tables shown below from TS 38 521-1 V17.4.1 (2022-07).
Sidelink RB allocations given in Table 6.1E-1 are used for V2X test cases. For modulation, Table A.7.5-1 is a good reference.
