Abstract:
A method, performed in a positioning node, for performing uplink positioning comprises receiving (210) of a request for uplink positioning of a user equipment. Information about carrier capabilities for uplink positioning measurements for carriers used in a serving cell of the user equipment is obtained (220). The method further comprises deciding (230) of which carrier to be used for uplink positioning measurements, based at least on the information about carrier capabilities. An uplink positioning measurement request for the user equipment using the carrier decided to be used for uplink positioning measurements is transmitted (250). Data representing said requested uplink positioning measurements is received (252). Complementing methods of cooperating network nodes are also disclosed as well as arrangements of the nodes.
