Abstract

A method, performed by a network node, is disclosed for handling positioning of a User Equipment, wireless device. The network node obtains a first approximate position of the wireless device, based on a first positioning procedure for the wireless device in a first frequency allocation. The network node determines, based on the first approximate position of the wireless device, a set of resources to be used for a second positioning procedure in a second frequency allocation. The network node initiates the second positioning procedure in the second frequency allocation using the determined set of resources. The network node obtains an updated position of the wireless device based on the second positioning procedure.

First claim

The invention claimed is:

1. A method, performed by a network node, for handling positioning of a wireless device, the method comprising:
receiving, from a device configured to transmit reference signals for a positioning procedure, a resource configuration of the device configured to transmit reference signals, comprising a first set of resources for a first positioning procedure in a first frequency allocation and a second set of resources for a second positioning procedure in a second frequency allocation, wherein the resource configuration comprises a positioning reference signal (PRS) configuration based on an association of the first set of resources on the first frequency allocation and the second set of resources on the second frequency allocation;
obtaining a first approximate position of the wireless device, based on a first positioning procedure for the wireless device in the first frequency allocation;
determining, based on the association and the obtained first approximate position of the wireless device, a set of resources to be used for a second positioning procedure in the second frequency allocation;
initiating the second positioning procedure in the second frequency allocation using the determined set of resources; and
obtaining an updated position of the wireless device based on the second positioning procedure.

2. The method according to claim 1 , wherein the obtaining the first approximate position of the wireless device comprises:
receiving, from a measuring device, measurement results indicative of the first positioning procedure for the wireless device in the first frequency allocation and
estimating, based on the received measurement results, the first position of the wireless device.

3. The method according to claim 1 , wherein the obtaining the updated position comprises:
receiving, from a measuring device, measurement results indicative of the second positioning procedure in the second frequency allocation; and
determining an updated position of the wireless device based on the measurement results from the second positioning procedure.

4. The method according to claim 1 , wherein the second frequency allocation is different than the first frequency allocation.

5. The method according to claim 4 , wherein the second frequency allocation comprises higher frequencies and/or a wider bandwidth than the first frequency allocation.

6. The method according to claim 1 , wherein the second positioning procedure is initiated within a preconfigured time gap from the first positioning procedure.

7. The method according to claim 1 , wherein the resource configuration is associated based on a geographical area covered by the resource configurations.

8. The method according to claim 1 , wherein the set of resources is associated with one or more radio network nodes, and/or with one or more beams of the measuring device.

9. The method according to claim 1 , wherein the device configured to transmit reference signals for a positioning procedure comprises a radio network node or a wireless device.

10. The method according to claim 1 , wherein the initiating a positioning measurement in the second frequency allocation using the determined set of resources comprises:
sending, to the device configured to transmit reference signals during the positioning procedure, an indication of the set of resources to be used for positioning procedures in the second frequency allocation.

11. The method according to claim 10 , wherein the sending, comprises sending the indication of the set of resources to be used for positioning procedures in the second frequency allocation to the measuring device.

12. A network node comprising a memory circuitry, a processor circuitry, and a wireless interface, wherein the wireless device is configured to perform the method of claim 1 .

13. A method, performed in a radio network node, for handling positioning of a wireless device, the method comprising:
performing a first positioning procedure of the wireless device in a first frequency allocation of a first set of resources;
receiving, from a network node, a set of resources comprising a positioning reference signal (PRS) configuration to be used for a second positioning measurement in a second frequency allocation, wherein the set of resources is associated with the first positioning procedure, and
performing the second positioning procedure of the wireless device in the second frequency allocation using the set of resources received from the network node.

14. The method according to claim 13 , wherein the second positioning procedure is performed within a preconfigured time gap from the first positioning procedure.

15. The method according to claim 13 , wherein the method further comprises:
sending, to the network node, measurement results indicative of the first positioning procedure of the wireless device in the first frequency allocation.

16. The method according to claim 13 , wherein the method further comprises:
sending, to the network node, a resource configuration of the radio network node.

17. The method according to claim 16 , wherein the PRS configuration of the radio network node comprises a PRS configuration of the radio network node for different frequency allocations, and an association of the PRS configurations for the different frequency allocations.

18. A radio network node comprising a memory circuitry, a processor circuitry, and a wireless interface, wherein the radio network node is configured to perform the method of claim 13 .

19. A method, performed in a wireless device, for handling positioning of the wireless device, the method comprising:
performing a first positioning procedure in a first frequency allocation of a first set of resources;
receiving, from a network node, a set of resources comprising a positioning reference signal (PRS) configuration to be used for a second positioning measurement in a second frequency allocation, wherein the set of resources are associated with the first positioning procedure, and
performing a second positioning procedure in the second frequency allocation using the set of resources received from the network node.

20. A wireless device comprising a memory circuitry, a processor circuitry, and a wireless interface, wherein the wireless device is configured to perform the method according to claim 19 .
