As shown in Fig. 3.53, the slot allocated for PDSCH transmis- sion is determined by parameter K of the indexed row n + K where n is the slot with the scheduling DCI, K0 is based on the numerology of PDSCH. The starting symbol S relative to (the start of the slot), and the number of consecutive symbols L counting from the symbol S allocated for the PDSCH are determined from the start and length indicator SLIV [14,15]. The slot allocated for the PDSCH is defined as | where UPDSCH and UPDCCH are the subcarrier spacing config- urations for PDSCH and PDCCH, respectively. If (L <7, SLIV = 14(L-1)+S; otherwise SLIV = 14(14 - L + 1) + (14 - where O<L < 14 - S and the PDSCH mapping type is set to Type A or Type B [15]. The per- missible S and L combinations corresponding to PDSCH allocations are shown Table 3.15. The PDSCH mapping type is related to the relative location of the demodulation refer- ence signal (DM-RS) and the slot boundary as well as the size of the data. The mapping type A is used when the first DM-RS is located in the second or third OFDM symbol of New Radio Access Physical Layer Aspects (Part 1) 399 HPDSCH 2 HPDCCH (Slot n) PDSCH S: Start symbol L: Number of consecutive symbols 2 "PDSCH 2HPDCCH ACK/NACK on PUCCH PDSCH (Slot n) 2 UPDSCH 2 HPDCCH PUSCH (Slot n) S: Start symbol L: Number of consecutive symbols Figure 3.53 Illustration of downlink/uplink time-domain resource allocation [12,15,39].
