1. A wireless device configured to receive positioning system information from a radio network node, the wireless device comprising a processor and a memory, the memory containing instructions executable by the processor to configure the wireless device to:
receive positioning system information scheduling information (pSI) from the radio network node;
receive, from the radio network node,
a scheduling offset;
determine in which subframes at least one system information message with positioning system information blocks (pSIM) is scheduled by the radio network node based on
the scheduling offset, a start subframe number a for a pSIM being determined as a=x mod 10 in a radio frame for which SFN mod T=Floor (x/10)+8, SFN being a system frame number, T being a system information (SI) periodicity of the pSIM, 8 being indicated by the scheduling offset and x being an integer value given by x=m*wm+(n−1*wn, m being a number of SI messages, wm being a window length of an SI message, n giving an order of entry in the list of pSIMs and being given by the pSI, and wn being a window length of the pSIM; and
use the determined scheduling of the at least one pSIM for receiving the at least one pSIM.
