1. An apparatus, comprising:
at least one processor; and
at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to perform:
sending, with a network node in a wireless network, a request of one or more settings useable with a reconfigurable reflecting surface for adjusting elements of the reconfigurable reflecting surface for one or more positioning reference signal transmissions from a base station toward a user equipment;
receiving, with the network node, one or more measurements taken with the user equipment for the one or more positioning reference signal transmissions, wherein the one or more positioning reference signal transmissions have a direct path between the base station and the user equipment and a reflection path that reflects off the reconfigurable reflecting surface; and
calculating, with the network node, a position coordinate corresponding to the user equipment using the one or more measurements with knowledge of a location of the reconfigurable reflecting surface;
wherein the calculating further comprises performing the calculation using a database, the database comprising positioning of user equipment and corresponding measurements and corresponding settings applied with the reconfigurable reflecting surface, that was constructed prior to the sending, receiving, and calculating.
