Claim 0:
1. A method comprising, receiving, at a user equipment, a first configuration of a first set of resources for positioning reference signal mapping to resource elements; receiving, at the user equipment, a second configuration of a second set of resources, wherein the second set of resources are a scalable extension of the first set of resources for positioning reference signal mapping to additional resource elements; and detecting, at the user equipment, positioning reference signals according to at least one of the first configuration of the first set of resources or the second configuration of the second set of resources; and measuring, at the user equipment, positioning accuracy using the first configuration of the first set of resources, and second configuration of the second set of resources; and providing a reliable cell for observed time difference of arrival (OTDOA) positioning algorithms, by performing both serving cell time of arrival (TOA) estimation and non-serving cell TOA estimation using the second set of resources.
