PDSCH PT-RS

The identifier of the physical layer cell, set as an integer from 0 before 1007.

The number of deleted objects in the telecom operator’s resource table, indicated as an integer from 1 before 275. The default value is 51, corresponds to the maximum number of resource blocks for the carrier 10 MHz and the distance between subcarriers 15 kHz.

The distance between subcarriers in kHz for all channels and carrier reference signals.

Values to choose from: 15 or 30 for FR1, 60 or 120 for FR2.

The length of the cyclic prefix. Options to choose from:

The number of data transmission layers for the PDSCH (Physical Downlink Shared Channel, physical channel of the common downlink) in 5G NR.

The number of antennas used to transmit the PDSCH (Physical Downlink Shared Channel) signal in the 5G standard NR.

The code word modulation scheme.

The code frequency in the form of a scalar in the range from 0 before 1024.

Enable or disable the use of a set of physically allocated resource blocks for data transfer. If this option is selected, you can use the parameter PDSCH PRB allocation, which sets specific frequency resource ranges for transmitting signals or data at the physical layer in 5G NR. This parameter determines which blocks of the available frequency spectrum can be assigned to the channel. Using PDSCH PRB allocation It allows you to specify specific groups of frequency blocks and flexibly allocate frequency resources depending on communication requirements and network conditions.

Ranges of frequency resources that can be used to transmit signals or data at the physical layer.

Dependencies

To use this option, check the box Enable PRBSet.

Enable or disable the use of phase change tracking signals (PT-RS, Phase Tracking Reference Signal) in the PDSCH (Physical Downlink Shared Channel) in 5G NR. PT-RS is used to correct and compensate for phase noise caused by instabilities of the transmitter and receiver. It is especially useful at high modulation orders, such as 256QAM or 1024QAM where the influence of phase errors can be significant. Enabling PT-RS improves data transmission quality by increasing synchronization accuracy, especially in conditions of frequency interference or fast movement.
