- Abstract: Nonlocality, one of the most puzzling features of multipartite quantum
correlation, has been identified as a useful resource for device-independent
quantum information processing. Motivated by the resource theory of quantum
entanglement recently an operational framework have been proposed by Gallego et
al. [\href{https://doi.org/10.1103/PhysRevLett.109.070401}{Phys. Rev. Lett.
109, 070401 (2012)}] and Bancal et al.
[\href{https://doi.org/10.1103/PhysRevA.88.014102}{Phys. Rev. A 88, 014102
(2013)}] that characterizes the nonlocal resource present in multipartite
quantum correlations. While the bipartite no-signaling correlations allows a
dichotomous classification -- local vs. nonlocal, in multipartite scenario the
authors have shown existence of several types of nonlocality that are
inequivalent under the proposed operational framework. In this work we present
a finer characterization of multipartite no-signaling correlations based on the
same operational framework. We also clarify a statement in Gallego et al.'s
work that could be misinterpreted and make the conclusions of that work more
precise here.

Bell inequalities by measurements on quantum states give rise to the phenomenon of quantum non-locality.
We show that while in the so-called correlation scenario the relative violation of bilocal Bell inequalities by quantum resources is bounded, it does not grow arbitrarily with the number of inputs.
We identify Bell functionals that take the form of non-local games for which the ratio of the quantum and bilocal values grows unboundedly as a function of the number of inputs and outputs.
