Abstract

A method performed by a wireless node is disclosed, for enabling positioning of a wireless device, WD. The method comprises receiving, from a location network node, assistance information comprising an estimated range of angles to be used for a positioning method of the WD. The method comprises performing a positioning method for the WD based on the assistance information.

Claims (24)

1 . A method, performed by a wireless node, for enabling positioning of a wireless device (WD) the method comprising:

receiving, from a location network node, assistance information comprising an estimated range of angles to be used for a positioning method of the WD, wherein the estimated range of angles is an estimated range of Angles of Arrival, AoA, at the wireless node of a reference signal received from the wireless device and/or an estimated range of Angles of Departure, AoD, from the wireless node of a reference signal transmitted to the wireless device, and

performing, for the estimated range of angles, a positioning method for the WD based on the assistance information, the positioning method comprises receiving, from the WD, one or more reference signals, and performing a positioning measurement based on the received one or more reference signals.

2 . The method according to claim 1 , wherein performing the positioning method comprises performing the positioning method for the estimated range of angles.

3 . The method according to claim 1 , wherein the estimated range of angles is a reduced range of angles which is a subset of a full range of angles available to the wireless node.

4 . The method according to claim 3 , wherein the method comprises: providing, to the location network node, a measurement report comprising a positioning measurement for the WD obtained during the positioning method, and wherein the measurement report comprises a first positioning measurement for the estimated range of angles and a second positioning measurement for a wider range of angles available to the wireless node.

5 . The method according to claim 1 , wherein the estimated range of angles is associated with an estimated position of the WD.

6 . The method according to claim 1 , wherein the estimated range of angles is an estimated range of angles of a first arrival path component of a reference signal transmission associated with the WD.

7 . The method according to claim 1 , wherein the method comprises: providing, to the location network node, a measurement report comprising a positioning measurement for the WD obtained during the positioning method.

8 . The method according to claim 7 , wherein the measurement report comprises an indication of whether the wireless node has applied the assistance information when performing the positioning method.

9 . The method according to claim 1 , wherein the assistance information comprises validation information indicative of a time duration for which the assistance information is valid.

10 . The method according to claim 9 , wherein the validation information comprises a starting time for when assistance information is valid.

11 . The method according to claim 1 , wherein the assistance information comprises reference information indicative of the reference direction of the estimated range of angles.

12 . The method according to claim 1 , wherein the assistance information comprises a WD identifier indicative of the WD for which the assistance information is valid.

13 . The method according to claim 1 , wherein the assistance information comprises a receive beam configuration for the estimated range of AoA for the wireless node.

14 . The method according to claim 13 , wherein the receive beam configuration comprises a number of receive beams to be used and/or a beamwidth for each of the receive beams.

15 . The method according to claim 1 , wherein performing the positioning method comprises:

transmitting, to the WD, reference signals in the estimated range of AoD, and

receiving, from the WD, a positioning measurement based on the reference signals transmitted in the estimated range of AoD.

16 . The method according to claim 1 , wherein the assistance information comprises a transmit beam configuration for the estimated range of AoD for the wireless node.

17 . A method, performed by a location network node, for positioning a wireless device (WD), the method comprising:

obtaining information indicative of a first position of the wireless device,

estimating, based on the information indicative of the first position, a range of angles to be used by a wireless node for a positioning method of the WD, wherein the range of angles is an estimated range of Angles of Arrival, AoA, at the wireless node, of a reference signal received from the wireless device and/or an estimated range of Angles of Departure, AoD, from the wireless node of a reference signal transmitted to the wireless device, and

transmitting, to the wireless node, assistance information comprising the estimated range of angles, wherein the wireless node performs, for the estimated range of angles, a positioning method for the WD based on the assistance information, the positioning method comprises receiving at the wireless node, from the WD, one or more reference signals, and performing a positioning measurement based on the received one or more reference signals.
