1. A method performed by a network node for providing positioning reference signals, PRS, the method comprising:
obtaining offset information relating to the transmission of at least one positioning reference signal;
delaying or advancing the transmission of the at least one positioning reference signal in accordance with the received offset information wherein the delaying or advancing according to the offset information shifts the transmission of the at least one positioning reference signal away from a scheduled transmission time for the at least one positioning reference signal transmission;
the network node is a first network node and the scheduled transmission time for the at least one PRS comprises a first physical resource allocation for the transmission of the at least one PRS in the first network node;
a second network node synchronised with the first network node being scheduled to transmit a corresponding at least one PRS in a corresponding second physical resource allocation; and
the shift away from the scheduled transmission time of the first network node comprising the first network node transmitting the at least one PRS in a third physical resource allocation which is different from said first and second physical resource allocation.
