The implications of a deformed Heisenberg algebra on the Friedmann-Robertson-Walker cosmological models are investigated. We consider the Snyder noncommutative space in which the translation group is undeformed and the rotational invariance preserved. When this framework is implemented to one-dimensional systems (which is this case) the modifications are uniquely fixed up to a sign. A cosmological quantum bounce a la loop quantum cosmology is then obtained. We also get the Randall-Sundrum braneworld scenario, and this way a Snyder-deformed quantum cosmology can be considered as a common phenomenological description for both theories.
