In plain words

In TS 38.331 V19.4.0, PDSCH-TimeDomainResourceAllocationList "contains one or more of such PDSCH-TimeDomainResourceAllocations.", containing one or more PDSCH time-domain allocation entries. Each entry configures the slot offset from DCI to its scheduled PDSCH, the PDSCH mapping type, and a joint index for start symbol and length. Each entry has three fields in V19.4.0, the same count as in Rel-15: k0, mappingType, and startSymbolAndLength.

How this page was made

The facts box comes straight from the 3GPP TDoc list and specification archive as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
