The example implements PUSCH and uplink transport channel (UL-SCH). For the general description of PTRS, I PTRS can be present both in the downlink (associated with PDSCH) and in the uplink (associated with PUSCH),. There are roughly three different types of UL transmission scheme : not-configured, codebook based and non-codebook based.

If transmitted, PTRS is always associated with one DMRS port and is confined to the scheduled bandwidth and duration of PDSCH/PUSCH,. Unspecified properties take their default values. For example, 'DMRSConfigurationType',1,'DMRSLength',2 specifies a double-symbol DM-RS with configuration type as 1. SequenceHopping = 0; % Sequence hopping (0 or 1) pusch. 3. The scope is to establish the characteristics of the Layer-1 physical channels For the Rel-17, 3GPP studied different 5G NR coverage enhancements, including enhancements for PUSCH, PUCCH and other channels/signals. . 1 . Hence, when the DMRS sequences are transmitted at lower power to avoid PA saturation, the coverage PUSCH DMRS (Physical Uplink Shared Channel Demodulation Reference Signals) is a concept in the context of 5G (and beyond) wireless communication systems. Both PDSCH and PUSCH has two different types of mapping called Type A and Type B. The main difference is that in Type1, DMRS is configured on six out of twelve resource elements in the frequency domain during one symbol, or 50% of resources, and the used resource elements are non-contiguous. 211 [3]. The example supports both clustered delay PUSCH DMRS can be configured only within the resources allocated for PUSCH, but SRS is configured outside of PUSCH even when PUSCH is not transmitted. As in LTE, many types of RS (Refernce Signal) are used in NR and most of them plays similar roles as in LTE. it is the most common combination used in the 5G networks today, be in low- or mid- or hi-band. The first variable purpose defines the physical channel for whom DMRS is to be generated and *args accepts variable inputs with different understanding based on the purpose . PUSCH DMRS - Uses the PUSCH DMRS specified by Source ID as the synchronization source. It is too big topics to be described in single page. In this page, I would try to give you only the big picture of the whole channel structure in NR, I would not get into the details of each type of channel processing separately. These 5G NR reference signals are used in the downlink and uplink. Massive MIMO has been a key component for achieving such a high throughput promised by 5G/NR.
