A system comprising:

• an apparatus;
• at least one processor;
• and
• at least one memory including computer program instructions that, when executed by the processor, cause the apparatus to perform the following operations:
• receiving Ultra-Wideband (UWB) Reference Signal (RS) configuration information, wherein the UWB RS configuration information comprises information for configuring a transmission or a reception of a UWB RS by the apparatus to or from at least one node of a Radio Access Network (RAN), wherein the UWB RS configuration information is received from a Location Management Function (LMF) via a serving Next Generation Node B (gNB) while the apparatus is in a Radio Resource Control (RRC) idle state, and wherein the UWB RS configuration information specifies (i) a Gaussian monocycle pulse type, (ii) a pulse width of 1 nanosecond, (iii) a bandwidth of 499.2 megahertz centered at 6.8 gigahertz, (iv) a periodicity of 20 milliseconds, (v) a transmission time offset of four Orthogonal Frequency-Division Multiplexing (OFDM) symbols from a frame start, and (vi) a one-millisecond transmission window;
• receiving, on paging resources offset by four slots relative to standard paging, a trigger identified as an nr-UWB-RequestLocationInformation message;
• and
• based at least in part on the received UWB RS configuration information and responsive to the trigger, causing, without transitioning the apparatus out of the RRC idle state and using a UWB transceiver that shares a reference clock locked to New Radio (NR), the transmission of exactly three identical UWB RS bursts within the one-millisecond window to exactly two Transmission Reception Points (TRPs) consisting of the serving gNB and one neighbor gNB, each burst conforming to the specified pulse type, width, bandwidth, center frequency, periodicity, and OFDM-symbol offset, wherein the UWB RS configuration information further indicates that the two TRPs perform Time of Arrival (TOA) and Angle of Arrival (AoA) measurements on the UWB RS and report results to the LMF.

A method performed by a user equipment (UE), the method comprising:

• receiving Ultra-Wideband (UWB) Reference Signal (RS) configuration information, wherein the UWB RS configuration information comprises information for configuring a transmission or a reception of a UWB RS by the UE to or from at least one node of a Radio Access Network (RAN), wherein the UWB RS configuration information is received from a Location Management Function (LMF) via a serving Next Generation Node B (gNB) while the UE is in a Radio Resource Control (RRC) idle state, and wherein the UWB RS configuration information specifies (i) a Gaussian monocycle pulse type, (ii) a pulse width of 1 nanosecond, (iii) a bandwidth of 499.2 megahertz centered at 6.8 gigahertz, (iv) a periodicity of 20 milliseconds, (v) a transmission time offset of four Orthogonal Frequency-Division Multiplexing (OFDM) symbols from a frame start, and (vi) a one-millisecond transmission window;
• receiving, on paging resources offset by four slots relative to standard paging, a trigger identified as an nr-UWB-RequestLocationInformation message;
• and
• based at least in part on the received UWB RS configuration information and responsive to the trigger, causing, without transitioning the UE out of the RRC idle state and using a UWB transceiver that shares a reference clock locked to New Radio (NR), the transmission of exactly three identical UWB RS bursts within the one-millisecond window to exactly two Transmission Reception Points (TRPs) consisting of the serving gNB and one neighbor gNB, each burst conforming to the specified pulse type, width, bandwidth, center frequency, periodicity, and OFDM-symbol offset, wherein the UWB RS configuration information further indicates that the two TRPs perform Time of Arrival (TOA) and Angle of Arrival (AoA) measurements on the UWB RS and report results to the LMF.
