Abstract

A method performed by a wireless device for configured Minimization of Drive Test, MDT, reporting includes obtaining a MDT configuration. The obtained MDT configuration is for one or more of immediate MDT and logged MDT. The MDT configuration is for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data, and the obtained MDT configuration comprising one or more of: a reportOnLeaveconfiguration; a reportQuantityRS-Indexes configuration; a maxNrofRS-IndexesToReport configuration: and an rsType configuration. The wireless device performs the one or more measurements according to the MDT configuration and provides an MDT report based on the one or more measurements.

Claims (74)

1. A method performed by a wireless device for configured Minimization of Drive Test, MDT, reporting, the method comprising:

obtaining a MDT configuration, wherein the obtained MDT configuration is for one or more of immediate MDT and logged MDT, the MDT configuration for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data, the obtained MDT configuration comprising three or more of:

a reportOnLeave configuration;

a reportQuantityRS-Indexes configuration;

a maxNrofRS-Indexes ToReport configuration;

an rsType configuration;

one or more A2 event specific configuration enhancements; and

one or more periodic event specific configuration enhancements;

performing the one or more measurements according to the MDT configuration; and

providing an MDT report based on the one or more measurements.

2. The method of claim 1 , wherein obtaining the MDT configuration comprises receiving the MDT configuration from a radio access network, RAN, node.

3. The method of claim 2 , wherein providing the MDT report comprises transmitting the MDT report to the RAN node.

4. The method of claim 1 , wherein the obtained MDT configuration configures the wireless device to include, in the MDT report, at least one of:

location information as requested by Operations, Administration, and Maintenance (OAM);

beam level information;

a best beam index of at least one of a New Radio (NR) camped cell;

a best beam index of one or more neighboring NR cells;

at least one beam level measurement quantity of the NR camped cell; and

at least one beam level measurement quantity of one or more neighboring NR cells.

5. The method of claim 1 , further comprising obtaining positioning assistance data from at least one of a RAN node and a location server.

6. The method of claim 5 , wherein the positioning assistance data is obtained together with the MDT configuration.

7. The method of claim 5 , further comprising:

retrieving positioning information based on the positioning assistance data; and

including the positioning information in the provided MDT report.

8. A method performed by a network node for configured Minimization of Drive Test, MDT, the method comprising:

determining a MDT configuration for a wireless device, wherein the MDT configuration is for one or more of immediate MDT and logged MDT, the MDT configuration for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data, the MDT configuration comprising three or more of the following:

a reportOnLeave configuration;

a reportQuantityRS-Indexes configuration;

a maxNrofRS-IndexesToReport configuration;

an rsType configuration;

one or more A2 event specific configuration enhancements; and

one or more periodic event specific configuration enhancements;

providing the MDT configuration to the wireless device; and

obtaining an MDT report from the wireless device.

9. The method of claim 8 , wherein the network node is a radio access network (RAN) node.

10. The method of claim 8 , wherein the MDT configuration is determined in cooperation with Operations, Administration, and Management (OAM), and the method further comprises providing the MDT report to OAM.

11. The method of claim 8 , wherein the MDT configuration configures the wireless device to include, in the MDT report, at least one of:

location information as requested by Operations, Administration, and Maintenance (OAM);

beam level information;

a best beam index of at least one of a New Radio (NR) camped cell;

a best beam index of one or more neighboring NR cells;

at least one beam level measurement quantity of the NR camped cell; and

at least one beam level measurement quantity of one or more neighboring NR cells.

12. The method of claim 8 , further comprising:

obtaining positioning assistance data from a location server; and

configuring the wireless device with the positioning assistance data.

13. The method of any one claim 12 , wherein configuring the wireless device with the positioning assistance data comprises:

providing the positioning assistance data together with the MDT configuration.

14. The method of claim 12 , further comprising:

obtaining positioning information from the wireless device, the positioning information based on the positioning assistance data.

15. The method of claim 14 , wherein the positioning information is included in the obtained MDT report.

16. A wireless device for configured Minimization of Drive Test, MDT, reporting, the wireless device comprising:

processing circuitry configured to:

obtain a MDT configuration, wherein the obtained MDT configuration is for one or more of immediate MDT and logged MDT, the MDT configuration for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data, the obtained MDT configuration comprising three or more of the following:

a reportOnLeave configuration;

a reportQuantityRS-Indexes configuration;

a maxNrofRS-IndexesToReport configuration;

an rsType configuration;

one or more A2 event specific configuration enhancements; and

one or more periodic event specific configuration enhancements;

perform the one or more measurements according to the MDT configuration; and

provide an MDT report based on the one or more measurements.

17. The wireless device of claim 16 , wherein the processing circuitry configured to obtain the MDT configuration comprises the processing circuitry configured to receive the MDT configuration from a radio access network, RAN, node.

18. A network node for configured Minimization of Drive Test, MDT, the network node comprising:

processing circuitry configured to:

determine a MDT configuration for a wireless device wherein the MDT configuration is for one or more of immediate MDT and logged MDT, the MDT configuration for performing one or more measurements associated with a specific reference signal type, beam level, or positioning assistance data, the MDT configuration comprising three or more of the following:

a reportOnLeave configuration;

a reportQuantityRS-Indexes configuration;

a maxNrofRS-IndexesToReport configuration;

an rsType configuration;

one or more A2 event specific configuration enhancements; and

one or more periodic event specific configuration enhancements;

provide the MDT configuration to the wireless device; and

obtain an MDT report from the wireless device.
