UL-SCH (Uplink Shared Channel)

The UL-SCH carries uplink user data. It is mapped to PUSCH physical channels.

Configure UL-SCH

Adds a new UL-SCH transport channel with the given subframe assignment and transmission configuration. All parameters except the subframe list are optional and use their preset defaults when omitted.

SCPI Command

[:SOURce]:RADio:LTETdd:WAVeform[:ARB]:CCARrier<channel>:ULINk:CONFig:ULSCh "<string>"

SCPI Example

RADio:LTETdd:WAVeform:CCARrier1:ULINk:CONFig:ULSCh "3;0;0;50;0,0;N/A;N/A;N/A;N/A;0;0;0;0"

Notes

The argument is a positional, semicolon-separated string of 13 fields (no keys):

subframe;modType;allocType;rbSize;rbOffset;S0;S1-1;S2;S3-1;nDMRS1;nDMRS2;deltaSS;hopping

subframe – uplink subframe number (required)

modType – 0 = QPSK, 1 = QAM16, 2 = QAM64

allocType – 0 = Type 0, 1 = Type 1

rbSize – number of resource blocks, 1–100 (Type 0 only; use N/A for Type 1)

rbOffset – resource-block offset(s) off0,off1, 0–99 (Type 0 only; N/A for Type 1)

S0, S1-1, S2, S3-1 – cluster RBG indices (Type 1 only; N/A for Type 0)

nDMRS1, nDMRS2 – DMRS cyclic-shift values

deltaSS – delta sequence-shift

hopping – 0 = Off, 1 = Group, 2 = Sequence

All fields except subframe are optional; omitted trailing fields use preset defaults. Use N/A for fields not applicable to the selected allocation type.

channelIdx – 0-based index of the UL-SCH to reconfigure (required)

subframe – uplink subframe number

modType – 0 = QPSK, 1 = QAM16, 2 = QAM64

allocType – 0 = Type 0, 1 = Type 1
