A length $ml$, index $l$ quasi-cyclic code can be viewed as a cyclic code of length $m$ over the field $\mathbb F_{q^l}$ via a basis of the extension $\mathbb F_{q^l}/\mathbb F_{q}$.
This cyclic code is an additive cyclic code.
In [C. Güneri, F. Özdemir, P. Solé, On the additive cyclic structure of quasi-cyclic codes, Discrete. Math., 341 (2018), 2735-2741], authors characterize
the $(l,m)$ values for one-generator quasi-cyclic codes for which it is
impossible to have an $\mathbb F_{q^l}$-linear image for any choice
of the polynomial basis of $\mathbb F_{q^l}/\mathbb F_{q}$.
But this characterization for some $(l,m)$
values is very intricate. In this paper, by the use of this characterization, we give a more simple characterization.
