General PUSCH Management

Add PUSCH - Adds a PUSCH to the transmission. When a PUSCH is added, a representative button is added at the top of the PUSCH parameter group.

When a new PUSCH is added, the new PUSCH will have First Symbol, Last Symbol, RB Offset and RB Number values that overlap (or conflict with) those of existing PUSCHs. If so, the conflicting parameters will change from black to orange until the conflicts are resolved.

Remove PUSCH - Removes the selected PUSCH.

Clear All - Removes all but the original PUSCH.

Enable Channels... - Quickly enables and disables the configured PUSCHs in a single dialog. You can also enable channels individually using the Enabled checkbox at the top of each PUSCH.

RNTI - Sets the Radio Network Temporary Identifier for the physical channel.

Default: 1

Range: 0-65535

Transform Precoding - Enables or disables Transform Precoding. When enabled, transform precoding is used for uplink waveforms (DFT discrete Fourier transform-s-OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. waveform type). When disabled, transform precoding is not used for uplink waveforms (CP 1) Contention period, or 2) Cyclic prefix-OFDM waveform type).

When Transform Precoding is selected, the MCS modulation and coding scheme Table choice for 64QAM changes to Table 64QAM(TP), which is specific to transform precoding. The table used in the Table 256QAM selection is the same for both transform precoding and non-transform precoding.

Pi/2 BPSK Binary phase shift keying - A type of phase modulation using 2 distinct carrier phases to signal ones and zeros. Support - Enables or disables support for π/2 BPSK modulation when Transform Precoding is enabled.

Modulation and Coding | Time/Freq Allocation

Modulation and Coding

RV Redundancy Version Index - Sets the RV index. This parameter is grayed out and not useable when a Custom ModFormat is selected.

Default: 0

LDPC low-density parity check decoding may fail in some cases for high QAM Quadrature Amplitude Modulation signals with RV Index set to 1 or 2.

MCS Table - Sets the MCS Table used for modulation of the data on the physical channel. This parameter is grayed out and not useable when a Custom ModFormat is selected.

The Slot Format, X Symbols, First Symbol and Last Symbol parameters are designed for maximum flexibility to allow for UE User Equipment (e.g. cell phone)-specific configurations. It is up to the user to decide what is needed for a valid configuration.

The UE needs to determine which symbols are used for PDSCH/PUSCH transmission, based on the First Symbol, Last Symbol, Slot format and X Symbol settings. The VSA software checks each symbol from First symbol to Last symbol to see whether it is D for PDSCH or U for Pusch. If a symbol is not valid, it is skipped.

Default: 1: U,U,U,U,U,U,U,U,U,U,U,U,U,U

UL Up Link (reverse link: from cell phone to base station) X Symbols - Sets the desired flexible (X) symbols within the selected slot format as uplink (U) symbols. After selecting a slot format, you can designate any X symbols within the format as U symbols by specifying them using this parameter.

Example:

Slot Format = 2: X X X X X X X X X X X X X X

UL X Symbols = 0,2,10:13

0,2 means X symbols 0 and 2 are used for Uplink

10:13 means X symbols 10, 11, 12, 13 are used for Uplink

Resulting Format = U X U X X X X X X X U U U U

The Slot Format, X Symbols, First Symbol and Last Symbol parameters are designed for maximum flexibility to allow for UE-specific configurations. It is up to the user to decide what is needed for a valid configuration.

Default: Blank (indicating no X symbols are used for Uplink)

Mapping Type - Sets the PUCSH mapping type.

Default: TypeA

Choices: TypeA, TypeB

TypeA Pos - Sets the the PUSCH DMRS position for mapping type A.

Default: Pos2

Choices: Pos2, Pos3

First Symbol - Sets the first symbol index in a slot used by the selected PUSCH.

Default: 1

The First Symbol parameter will change color to orange when one of the following cases occurs:

First Symbol index is not compliant with NR standard. See below for more information.
Symbol length is not compliant with NR standard.
There is an overlap of symbol allocation between physical channels.

Valid PUSCH allocations are based on table 6.1.2.1-1 of the 5G NR standard:

Table 6.1.2.1-1: Valid S and L combinations

PUSCH mapping type	Normal cyclic prefix			Extended cyclic prefix
PUSCH mapping type	S	L	S+L	S	L	S+L
Type A	0	{4,…,14}	{4,…,14}	0	{4,…,12}	{4,…,12}
Type B	{0,…,13}	{1,…,14}	{1,…,14}	{0,…,12}	{1,…,12}	{1,…,12}

Last Symbol - Sets the last symbol index in a slot used by the selected PUSCH.

Default: 13

The Last Symbol parameter will change color to orange when one of the following cases occurs:

First Symbol index is not compliant with NR standard. See First Symbol for more information.
Symbol length is not compliant with NR standard.
There is an overlap of symbol allocation between physical channels.

RA 1) Random Access, or 2) Receiver Address Type - Sets the resource allocation type. Type0 uses a bitmap allocation method. Type1 uses RB Offset and RB Number for allocation.

Default: Type1

Choices: Type0, Type1

RB Number Restricted - Enables or disables the RB number limitation for PUSCH when Transform Precoding is enabled.

RB Number Restricted is used when PUSCH Transform Precoding is ON, to comply with RB number limitations specified in TS38.211. Disable this parameter if you want to experiment with PUSCH transform precoding without the standard-based limitation.

Default: Enabled

Choices: Enabled, disabled

RB Offset - Sets the start index of resource block assigned to the selected PUSCH physical channel. This value specifies the RB starting point within the containing resource allocation.

	You can now have multiple PDSCHs/PUSCHs with overlapping time and frequency allocations, allowing each PDSCH/PUSCH to use same or different set of allocated slots, symbols and RBs within the overlapping resources. For a successful measurement, the Antenna Ports of the overlapped users must be orthogonal.
	UL-BWP RB Offset is independent of the RB Offset settings for the physical channel.

Default: 0

RB Number - Sets the number of resource blocks assigned to the selected PUSCH physical channel. This value specifies the contiguous set of RB starting at RB Offset within the containing resource allocation.

	You can use Low SNR Mode for troubleshooting when EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. is unexpectedly high and the RB Number is small (e.g., 2 or 3).
	You can now have multiple PDSCHs/PUSCHs with overlapping time and frequency allocations, allowing each PDSCH/PUSCH to use same or different set of allocated slots, symbols and RBs within the overlapping resources. For a successful measurement, the Antenna Ports of the overlapped users must be orthogonal.
	The RB Number settings for the PUSCH and PUCCH physical channels are constrained by the UL-BWP RB Number setting value.
	Currently only the VSA supports continuous physical RB allocation.

Default: Matches the value of UL-BWP RB Number

RA Configuration - When RA Type is set to Type0, RA Configuration sets PUSCH-Config, which determines the nominal RBG Size [P] based on the bandwidth part size (RB Number), as specified in 5GNR standard 3GPP 38.214 Release 18 version 18.1.0 (2023-12) Table 6.1.2.2.1-1.

It must be present in sufficient power in the Ref. Meas. Channel to make a successful measurement. The Ref. DMRS Port and Ref. Meas. Channel settings are also used to determine a reference for per-path metrics presented in the MIMO Info summary table. This affects both single input channel measurements of multi-port transmissions, and multiple input channel measurements of multi-port transmissions.

Default: 0

For VSA 25.20 and later, n_ID^Nscid is obsoleted, and Nscid, n_ID^DMRS Source, N_ID⁰ and N_ID¹ are used for DMRS sequence generation. When Nscid is 0 and n_ID^DMRS Source is From RRC (higher layer), N_ID⁰ is used as n_ID^Nscid. When Nscid is 1 and n_ID^DMRS Source is From RRC (higher layer), N_ID¹ is used as n_ID^Nscid.

For VSA 25.20 and later, n_ID^Nscid is obsoleted, and Nscid, n_ID^DMRS Source, N_ID⁰ and N_ID¹ are used for DMRS sequence generation. When Nscid is 0 and n_ID^DMRS Source is From RRC (higher layer), N_ID⁰ is used as n_ID^Nscid. When Nscid is 1 and n_ID^DMRS Source is From RRC (higher layer), N_ID¹ is used as n_ID^Nscid.

For VSA 5G NR measurements, the software doesn't check whether the PUSCH is a msg3 transmission or if the transmission is scheduled using DCI format 0_0 in a common search space. As long as Transform Precoding and Pi/2 BPSK Support are enabled and DMRS-UplinkTransformPrecoding-r16 is configured (checked), the n_ID^RS will be calculated based on Nscid, N_ID⁰ and N_ID¹.
