In plain words

MeasConfig specifies measurements for the user equipment (UE) and covers "intra-frequency, inter-frequency and inter-RAT mobility as well as configuration of measurement gaps". Its lists support adding or modifying measurement objects and removing measurement objects or reporting configurations. In TS 38.331 V19.4.0, its SEQUENCE has 15 fields: 10 from Rel-15, one each from Rel-16 and Rel-18, and three from 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.
