In plain words

In clause 4, TR 21.905 V19.2.0 describes NBIN as "A parameter in the hopping sequence". Clause 6.2.3 of TS 45.002 V19.0.0 covers hopping sequence generation and gives the expression M' = M modulo (2 ^ NBIN). The displayed expression places NBIN in the modulus calculation for M' during hopping sequence generation.

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.
