NR PUSCH Resource Allocation and DM-RS and PT-RS Reference ...
Symbol allocation of PUSCH indicates the OFDM symbol locations allocated for the PUSCH transmission in a slot. The mapping type indicates the first DM-RS OFDM symbol location and the duration of OFDM symbols (l d).For mapping type A, l d is the duration between the first OFDM symbol of the slot and the last OFDM symbol of the allocated PUSCH resources.

NR Physical Layer Overview
The time domain resource allocation assignment field points into a row in a table. The table will give the PUSCH mapping type, which slot the PUSCH is allocated in, the starting OFDM symbol in the slot the PUSCH is allocated and the length of OFDM symbols of the PUSCH. The PUSCH mapping type corresponds to the OFDM symbols which contain DMRS.
