In plain words
AdvancedReceiver-MU-MIMO provides assistance information for reduced complexity ML receivers "with enhanced inter-user interference suppression for MU-MIMO transmissions". In Rel-18, its SEQUENCE has four fields covering precoding and resource allocation, PDSCH time-domain allocation, an MCS table, and DCI 1_1 assistance. TS 38.331 V19.4.0 references it from PDSCH-Config.

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.
