Abstract

Claims (67)

1 . A method of wireless communication performed by a receiver device, comprising:

performing, during a positioning session, a measurement of a first positioning reference signal (PRS) within a first bandwidth part (BWP);

performing, during the positioning session, a measurement of a second PRS within a second BWP;

transmitting, to a location server, a measurement report including the measurement of the first PRS and the measurement of the second PRS;

transmitting, to the location server, an indicator that a change from the first BWP to the second BWP occurred between the measurement of the first PRS and the measurement of the second PRS; and

transmitting, to the location server, an indication of the first BWP, the second BWP, or both in response to the change from the first BWP to the second BWP.

2 . The method of claim 1 , wherein the transmitting the indication comprises:

transmitting, to the location server, an identifier of the first BWP, a time period during which the receiver device measured the first PRS within the first BWP, or both; and

transmitting, to the location server, an identifier of the second BWP, a time period during which the receiver device measured the second PRS within the second BWP, or both.

3 . The method of claim 1 , wherein the transmitting the indication comprises:

transmitting, to the location server, an identifier of the first BWP based on the receiver device measuring the first PRS within the first BWP for a longest duration.

4 . The method of claim 1 , wherein the transmitting the indication comprises:

transmitting, to the location server, an identifier of the second BWP based on the receiver device measuring the second PRS last within the positioning session.

5 . The method of claim 1 , wherein the transmitting the indication comprises:

transmitting, to the location server, an identifier of the first BWP based on the receiver device measuring the first PRS first within the positioning session.

6 . The method of claim 1 , wherein the transmitting the indicator comprises:

transmitting, to the location server, a quality report status indicator indicating that the change from the first BWP to the second BWP occurred.

7 . The method of claim 1 , wherein the indicator indicates a time at which the change from the first BWP to the second BWP occurred.

8 . The method of claim 1 , wherein the indicator includes a system frame number (SFN) or a slot identifier during which the change from the first BWP to the second BWP occurred.

9 . The method of claim 1 , wherein the indication is included in the measurement report.

10 . The method of claim 1 , wherein the indication is not included in the measurement report.

11 . The method of claim 1 , wherein the receiver device is a user equipment (UE), and wherein the first PRS and the second PRS are downlink PRS transmitted by a base station.

12 . The method of claim 1 , wherein the receiver device is a base station, and wherein the first PRS and the second PRS are uplink PRS transmitted by a UE.

13 . The method of claim 12 , further comprising:

receiving an indication that the UE is engaged in the positioning session with the location server; and

transmitting, to the location server, the indication of the first BWP, the second BWP, or both in response to reception of the indication that the UE is engaged in the positioning session.

14 . A receiver device, comprising:

a memory;

one or more transceivers; and

one or more processors communicatively coupled to the memory and the one or more transceivers, the one or more processors, either alone or in combination, configured to:

perform, during a positioning session, a measurement of a first positioning reference signal (PRS) within a first bandwidth part (BWP);

perform, during the positioning session, a measurement of a second PRS within a second BWP;

transmit, via the one or more transceivers, to a location server, a measurement report including the measurement of the first PRS and the measurement of the second PRS;

transmit, via the one or more transceivers, to the location server, an indicator that a change from the first BWP to the second BWP occurred between the measurement of the first PRS and the measurement of the second PRS; and

transmit, via the one or more transceivers, to the location server, an indication of the first BWP, the second BWP, or both in response to the change from the first BWP to the second BWP.

15 . The receiver device of claim 14 , wherein the one or more processors being configured to transmit the indication comprises the one or more processors, either alone or in combination, being configured to:

transmit, via the one or more transceivers, to the location server, an identifier of the first BWP, a time period during which the receiver device measured the first PRS within the first BWP, or both; and

transmit, via the one or more transceivers, to the location server, an identifier of the second BWP, a time period during which the receiver device measured the second PRS within the second BWP, or both.

16 . The receiver device of claim 14 , wherein the one or more processors being configured to transmit the indication comprises the one or more processors, either alone or in combination, being configured to:

transmit, via the one or more transceivers, to the location server, an identifier of the first BWP based on the receiver device measuring the first PRS within the first BWP for a longest duration.

17 . The receiver device of claim 14 , wherein the one or more processors being configured to transmit the indication comprises the one or more processors, either alone or in combination, being configured to:
