Positioning device and method for calculating a position of a mobile device
The present invention relates to determining a position of a mobile device, and in particular signaling for on-demand positioning reference signal configuration, for example, in 5G new radio. The present invention provides a positioning device for calculating a position of a mobile device. The positioning device is configured to determine a measurement quality, and/or a reference signal type and configuration based on a positioning request, to determine a reference signal configuration request based on at least the measurement quality, and/or the reference signal type and configuration, to obtain a measurement result based on a reference signal configured according to the reference signal configuration request, and to calculate the position based on at least the measurement result.
1. A positioning device for calculating a position of a mobile device, comprising:
a processor; and
a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions, that when executed by the processor, cause the processor to:
determine a measurement quality, and/or reference signal information based on a positioning request, the reference signal information including a reference signal type or a reference signal configuration,
determine a reference signal configuration request based on at least the determined measurement quality, and/or the determined reference signal information,
obtain a measurement result based on a reference signal configured according to the determined reference signal configuration request, and
calculate the position based on at least the obtained measurement result,
wherein the reference signal type is a downlink (DL) reference signal type, and the reference signal configuration request comprises a request for a DL reference signal, and the obtaining of the measurement result based on the reference signal configured according to the determined reference signal configuration request comprises:
sending the reference signal configuration request to a radio resource controller (RRC), and
receiving a DL reference signal configuration for configuring the reference signal.
2. The positioning device according to claim 1 , wherein the reference signal configuration request comprises at least one of a first measurement report configuration, a configuration, a periodicity, or a number of repetitions.
3. The positioning device according to claim 1 , wherein the reference signal configuration comprises at least one of a second measurement report configuration, a granted configuration, a periodicity, or a number of repetitions.
4. A method for calculating a position of a mobile device, comprising:
determining a measurement quality, and/or reference signal information based on a location request, the reference signal information including a reference signal type and a reference signal configuration,
determining a reference signal configuration request based on at least the determined measurement quality, and/or the determined reference signal information,
obtaining a measurement result based on a reference signal configured according to the determined reference signal configuration request, and
calculating the position, based on at least the obtained measurement result,
wherein the reference signal type is a downlink (DL) reference signal type, and the reference signal configuration request comprises a request for a DL reference signal, and the obtaining of the measurement result based on the reference signal configured according to the determined reference signal configuration request comprises:
sending the reference signal configuration request to a radio resource controller (RRC), and
receiving a DL reference signal configuration for configuring the reference signal.
