dc.description.abstract	The definition of Milnor-Witt cycle modules in [5] can easily be adapted over general regular base schemes. However, there are simple examples (see (2.9)) to show that Gersten complex fails to be exact for cycle modules in general if the base is not a field. The goal of this article is to show that, for a restricted class of Milnor-Witt cycle modules over an excellent DVR satisfying an extra axiom, called here as R5, the expected properties of exactness of Gersten complex and A1-invariance hold. Moreover R5 is vacuously satisfied when the base is a field and it is also satisfied by KMW over any base. As a corollary, we obtain the strict A1-invariance and the exactness of Gersten complex for KMW over an excellent DVR	en_US
