In plain words

RXLEV means received signal level, as defined in 3GPP TR 21.905. In TS 45.008, a measured signal level "shall be mapped to an RXLEV value between 0 and 63, as follows:" TS 44.318 codes RXLEV-NCELL as the binary representation of a value N, while TS 51.021 nominally maps RXLEV to received signal level.

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.
