Embodiment Construction

[0131] figure 1 A positioning device 100 according to an embodiment of the present application is shown. The positioning device 100 is used to calculate the location 106 of the mobile device.

[0132] like figure 1As shown, the positioning device 100 is configured to determine the measurement quality 102 and / or the reference signal type 103a and the configuration 103b based on the positioning request 101 . The positioning device 100 is further configured to: determine a reference signal configuration request 104 based on at least the measurement quality 102 and / or the reference signal type 103a and configuration 103b to obtain a measurement result 105 based on reference signals configured according to the reference signal configuration request 104, and The location 106 is calculated based on at least the measurements 105 .

[0133] The reference signal type 103a may be at least one of a DL reference signal type, a UL reference signal type, or an SL reference signal type.

Abstract

The present application relates to determining the location of a mobile device, and in particular to signaling for on-demand positioning reference signal configuration, eg in 5G New Radio. The application provides a positioning device (100) for computing a location (106) of a mobile device. The positioning device (100) is configured to: determine the measurement quality (102) and / or the reference signal type (103a) and the configuration (103b) based on the positioning request (101); based on at least the measurement quality (102) and / or the reference signal type (103a) and configure (103b) to determine a reference signal configuration request (104); obtain a measurement result (105) based on a reference signal configured according to the reference signal configuration request (104); and calculate a position based on at least the measurement result (105) (106).

Description

technical field [0001] The present application relates to devices, methods, and systems for determining the location of a mobile device. The present application particularly relates to signaling for on-demand positioning reference signal (RefSig) configuration in 5G new radio (NR). Background technique [0002] In the prior art, high-precision positioning has been identified as one of the key features of next-generation cellular systems, and many positioning use cases have been investigated. Performance gaps in positioning accuracy have been found to be found, especially in global navigation satellite system (GNSS)-denied environments. Given the potential of NR radio access technology (RAT), 5G location / location services are designed for commercial positioning use cases and support a range of accuracy levels, latency levels and device classes. Such services should also take advantage of high bandwidth, large scale antenna systems, network architecture / functionality (eg, he...
