NR POSITIONING ENHANCEMENT FOR TIMING AND ANGLE BASED METHODS AND RESOURCE AGGREGATION
A method may include generating a receive timing error group (Rx TEG) based on a time delay of a receive (Rx) signal, wherein the time delay is a time measured from an arrival of the Rx signal at a Rx antenna to a time of the Rx signal being digitized and time-stamped at a baseband processor of a user equipment (UE), determining a timing error group (TEG) index corresponding to the generated Rx TEG, determining a positioning measurement associated with the Rx antenna used to generate the Rx TEG, and reporting the positioning measurement associated with the Rx TEG index.
1 . A method, comprising:
determining, during a timing window in a time domain, a reference signal received power (RSRP) for an i-th path delay at a user equipment (UE);
measuring the RSRP of an arrival of the i-th path delay; and
reporting the measured RSRP for the i-th path delay to a location server, wherein the measured RSRP for the i-th path delay is a power of a received downlink (DL) position reference signal (PRS) configured for measurement at the i-th path delay of a channel response.
2 . The method of claim 1 , wherein the RSRP is a PRS RSRP.
3 . The method of claim 1 , wherein the reporting the measurement RSRP comprises M paths configured by a Location Management Function (LMF).
4 . The method of claim 3 , wherein M is a value selected from 1, 3, 5, 17, or 33.
5 . The method of claim 1 , further comprising receiving a measurement request from an LMF to specify paths for the reporting the measure RSRP.
6 . The method of claim 2 , further comprising:
determining a phase of the PRS RSRP corresponding to a first arrival path and additional N≥2 paths, wherein N≥2; and
reporting the phase to the location server.
7 . The method of claim 2 , further comprising:
determining a phase and an amplitude of the PRS RSRP corresponding to a first arrival path and additional N paths, where N≥2; and
reporting the phase and the amplitude to the location server.
8 . The method of claim 1 , further comprising:
determining an arrival time of the PRS RSRP corresponding to a first arrival path and additional N paths, where N≥2; and
reporting the arrival time to the location server.
9 . A method, comprising:
determining a per-band combination (per-BC) maximum value of a position reference signal (PRS) for each frequency band and each carrier aggregation (CA) type; and
reporting a largest one of the per-BC maximum value to a location server.
10 . The method of claim 9 , further comprising reporting a 3-tuple indicator to the location server, wherein the 3-tuple indicator comprises a maximum value of the PRS across Frequency Range 1 (FR1), a maximum value of the PRS across Frequency Range 2 (FR2), and a mixed maximum value of the PRS across both the FR1 and the FR2.
11 . The method of claim 10 , wherein the 3-tuple indicator is different for an intra-band contiguous CA, an intra-band non-contiguous CA, and inter-band CA.
12 . The method of claim 10 , further comprising reporting a 5-tuple indicator to the location server, wherein the 5-tuple indicator comprises a maximum value of the PRS for frequency bands in the FR1 in response to the per-BC comprising only the frequency bands in the FR1.
13 . The method of claim 10 , further comprising reporting a 5-tuple indicator to the location server, wherein the 5-tuple indicator comprises a maximum value of the PRS for frequency bands in the FR2 in response to the per-BC comprising only the—frequency bands in the FR2.
14 . The method of claim 10 , further comprising reporting a 5-tuple indicator to the location server, wherein the 5-tuple indicator comprises a maximum value of the PRS for frequency bands in the FR1 in response to the per-BC comprising both the FR1 and the FR2 bands.
15 . The method of claim 10 , further comprising reporting a 5-tuple indicator to the location server, wherein the 5-tuple indicator comprises a maximum value of the PRS for frequency bands in the FR2 in response to the per-BC comprising both the FR1 and the FR2 bands.
16 . The method of claim 10 , further comprising reporting a 5-tuple indicator to the location server, wherein the 5-tuple indicator comprises a maximum value of the PRS for frequency bands in the FR1 and the FR2 in response to the per-BC comprising both the FR1 and the FR2 bands.
