PUSCH PT-RS
PUSCH phase tracking reference signals (PT-RS).
Description
The block PUSCH PT-RS generates Phase-tracking reference signals (PT-RS) symbols for the physical uplink common channel (PUSCH), in accordance with section 6.4.1.2.1 of the standard [1].

Start of carrier resource grid relative to CRB 0 —
start of the carrier resource grid relative to CRB 0
Real number
Details
Parameters that indicates from which Resource Block (RB) the carrier resource grid starts if CRB 0 is taken as the start (zero point).
CRB 0 (Carrier Resource Block 0) is the base, counted as the first resource block, against which all addressing of the grid takes place.

#
Transform precoding —
inclusion of pre-coding with conversion
Logical
Details
If this checkbox is selected, a data processing method is applied that is used to improve the spatial and frequency redundancy of the channel. This method uses pre-processing that transforms the data before it is modulated and transmitted through the antennas. It includes steps such as spectral and spatial transform to reduce interference and improve channel performance.
If this box is unchecked, standard data coding and modulation is used without applying complex transformations.

Details

#
Mapping type —
PUSCH display type
A | B
Details
A parameter in modern communication systems such as LTE and 5G that determines how logical or physical resources are assigned (or mapped) to data on a channel. Options to select:
-
Ais the standard mapping type in which each logical resource (e.g., a symbol in the time or frequency domain) is mapped to specific physical resources. TypeAis used for conventional mapping schemes where each logical channel group is mapped to fixed resources. -
Bis a more flexible scheme where resources can be reallocated dynamically depending on the channel state and system requirements. It allows the system to adapt to changes in link conditions.

Enable or disable PT-RS —
usage of phase change tracking signals
Logical
Details
Enable or disable usage of PT-RS (Phase Tracking Reference Signal) on the Physical Uplink Shared Channel (PUSCH) in 5G NR. If this checkbox is selected, PT-RS is used to improve signal quality. If unchecked, PT-RS is not used, which can reduce reliability in high phase noise environments.

#
Frequency hopping —
frequency switching
neither | intraSlot | interSlot
Details
Options for selection:
-
neither- data transmission is performed in the same frequency range. -
intraSlot- frequency changes within one slot. Useful at high speeds of User equipment (UE) as it reduces the effect of Doppler shift. -
interSlot- the frequency varies between slots. This helps to reduce interference and make the transmission more immune to interference.
