In plain words

PUSCH-Config is used to "configure the UE specific PUSCH parameters applicable to a particular BWP." Its fields identify PUSCH data scrambling, select codebook or non-codebook based transmission, and configure power control for PUSCH transmission. The ASN.1 SEQUENCE has 86 fields: 18 in Rel-15, 32 in Rel-16, 17 in Rel-17, 9 in Rel-18, and 10 in Rel-19.

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.
