(72) GUNNARSSON, Fredrik (SE) et SHREEVASTAV, Ritesh (SE) (73) TELEFONAKTIEBOLAGET LM ERICSSON (PUBL), 164 83 STOCKHOLM (SE) (74) Cabinet BONNY & ASSOCIÉS, LAW FIRM, B.P. 35349, YAOUNDE (CM). (57) Embodiments include methods for a positioning node coupled to a radio access network (RAN). Such methods include determining first spatial relations between downlink reference signals (DLRS) and uplink reference signals (UL-RS) used for positioning in a first cell served by a first RAN node; and determining second spatial relations between DL-RS and UL-RS used for positioning in one or more second cells served by a second RAN node. The first cell is a serving cell for a user equipment (UE) and the second cells are neighbor cells to the first cell. Such methods include configuring the UE to transmit UL-RS according to the first and second spatial relations. Embodiments include complementary methods for the first RAN node and for the UE, as well as positioning nodes, RAN nodes, and UEs configured to perform such methods.
