Abstract

Example Embodiments presented herein are directed towards a radio node ( 101, 130, 102 ), and corresponding methods therein, for fingerprinting positioning measurements. The radio node may be configured to provide a fingerprinting measurement result comprising radio channel related information. Non-limiting examples of radio channel information may be Doppler, speed and/or delay spread information. Example embodiments presented herein may also be directed towards a positioning node ( 140 ), and corresponding methods therein, for fingerprinting positioning management. The positioning node may be configured to receive radio channel related information from the radio node and generate a radio fingerprint based on the received radio channel related information.

First claim

The invention claimed is:

1. A method for fingerprinting positioning measurement, the method being implemented by a radio node in a wireless communications network and comprising:
requesting to receive radio channel-related information;
receiving the radio channel-related information by the radio node;
performing a fingerprinting positioning measurement based on a location-related request; and
enhancing the fingerprinting positioning measurement with the radio channel-related information;
analyzing a measurement result with respect to a reference measure;
obtaining a relative difference or ratio based on the analyzing;
reporting the measurement result of the fingerprinting positioning measurement in a positioning-related message to a network node, wherein the measurement result comprises the fingerprinting positioning measurement enhanced with the radio channel-related information for use in optimizing signal transmissions, and wherein the radio channel-related information comprises at least one of Doppler information, speed information, and delay spread information;
receiving, from the network node, alteration instructions based on the measurement result; and
altering the fingerprinting positioning measurement based on the alteration instructions to select or re-select assistance nodes and type of measurements.

2. The method of claim 1 wherein the fingerprinting positioning measurement, the measurement result, or both, are associated with at least one of:
an Adaptive Enhanced Cell Identification;
an Enhanced Cell Identification;
Radio Frequency fingerprinting; and
pattern matching.

3. The method of claim 1 further comprising receiving the location-related request from a network node.

4. The method of claim 1 further comprising receiving the location-related request within the radio node based on an internal configuration setting.

5. The method of claim 1 wherein the performing further comprises analyzing the measurement result with respect to at least one pre-defined threshold related to an environmental characteristic.

6. The method of claim 1 wherein the performing further comprises performing the fingerprinting positioning measurement based on uplink or downlink physical signals and/or channels.

7. The method of claim 1 wherein the fingerprinting positioning measurement is performed in an intra-frequency configuration, an inter-frequency configuration, or an inter-Radio Access Technology configuration.

8. The method of claim 1 wherein the performing further comprises aggregating the measurement result to reflect multiple cells.

9. The method of claim 1 wherein the positioning-related message is an assistance data request message or a measurement report message.

10. The method of claim 1 wherein the measurement result comprises a radio fingerprint.

11. A radio node for fingerprinting positioning measurement, the radio node being part of a wireless communications network and comprising:
a receiver configured to receive radio channel-related information requested by the radio node;
measurement circuitry configured to:
perform a fingerprinting positioning measurement according to a location-related request; and
enhance the fingerprinting positioning measurement with the radio channel-related information;
analyze the measurement result with respect to a reference measure; and
obtain a relative difference or ratio based thereon;
a transmitter configured to report, to a network node, a measurement result of the fingerprinting positioning measurement in a positioning message, wherein the measurement result comprises the fingerprinting positioning measurement enhanced with the radio channel-related information for use in optimizing signal transmissions,
wherein the radio channel-related information comprises at least one of Doppler information, speed information, and delay spread information; and
wherein the receiver is further configured to:
receive, from the network node, alteration instructions based on the measurement result; and
wherein the measurement circuitry is further configured to alter the fingerprinting positioning measurement based on the alteration instructions to select or re-select assistance nodes and type of measurements.

12. The radio node of claim 11 wherein the network node is a positioning node or a gateway node.

13. The radio node of claim 11 wherein the radio node is one of:
a user equipment;
a base station;
a Location Measurement Unit; or
a gateway node.

14. The radio node of claim 11 wherein the fingerprinting positioning measurement, the measurement result, or both, are associated with at least one of:
an Adaptive Enhanced Cell Identification;
an Enhanced Cell Identification;
Radio Frequency fingerprinting; and
pattern matching.

15. The radio node of claim 11 wherein the receiver is further configured to receive the location-related request from the network node.

16. The radio node of claim 11 wherein the measuring circuitry is further configured to receive the location-related request based on an internal configuration setting.

17. The radio node of claim 11 wherein the measurement circuitry is further configured to analyze the measurement result with respect to at least one pre-defined threshold related to an environmental characteristic.

18. The radio node of claim 11 wherein the measurement circuitry is further configured to perform the fingerprinting positioning measurement based on uplink or downlink physical signals and/or channels.

19. The radio node of claim 11 wherein the measurement circuitry is further configured to perform the fingerprinting positioning measurement in an intra-frequency configuration, an inter-frequency configuration, or an inter-Radio Access Technology configuration.

20. The radio node of claim 11 wherein the measurement circuitry is further configured to aggregate the measurement result to reflect multiple cells.

21. The radio node of claim 11 wherein the measurement result comprises a radio fingerprint.

22. The radio node of claim 11 wherein the positioning-related message is an assistance data request or a measurement report message.
