Abstract

Claims (41)

1 . A user equipment (UE) comprising:

a transceiver configured to receive, from a first transmit receive point (TRP), a first downlink (DL) position reference signal (PRS); and

a processor operably coupled to the transceiver, the processor configured to perform a measurement for the DL PRS, and

wherein the transceiver is further configured to transmit, to the first TRP, a first report for the measurement,

wherein the first report includes a DL reference signal carrier phase (RSCP) associated with a center frequency for the DL PRS, and

wherein the DL RSCP is associated with a first path derived from first resource elements for carrying the DL PRS.

2 . The UE of claim 1 , wherein the first report further includes at least one of a UE receive-transmit time difference, a DL PRS reference signal received power (RSRP), and a DL PRS reference signal received path power (RSRPP) of the DL PRS.

3 . The UE of claim 1 , wherein the first report further includes a time stamp indicating a symbol index associated with the DL RSCP.

4 . The UE of claim 1 , wherein the first report further includes a line of sight (LoS) indicator or a non line of sight (NLOS) indicator.

5 . The UE of claim 1 , wherein the transceiver is further configured to transmit, to a second TRP, an uplink (UL) sounding reference signal (SRS) for positioning of an UL RSCP associated with a center frequency of the UL SRS.

6 . The UE of claim 5 , wherein:

the UL SRS is for the positioning of at least one of a relative time of arrival (RTOA), an UL SRS reference signal received power (RSRP), and an UL SRS reference signal received path power (RSRPP), and

the UL RSCP is associated with a second path derived from second resource elements for carrying the UL SRS.

7 . A transmit receive point (TRP) comprising:

a processor; and

a transceiver operably coupled to the processor, the transceiver configured to:

transmit, to a user equipment (UE), a downlink (DL) positioning reference signal (PRS); and

receive, from the UE, a first report for a measurement,

wherein the first report includes a DL reference signal carrier phase (RSCP) associated with a center frequency for the DL PRS, and

wherein the DL RSCP is associated with a first path derived from first resource elements for carrying the DL PRS.

8 . The TRP of claim 7 , wherein the first report further includes at least one of a UE receive-transmit time difference, a DL PRS reference signal received power (RSRP), and a DL PRS reference signal received path power (RSRPP) of the DL PRS.

9 . The TRP of claim 7 , wherein the first report further includes a time stamp indicating a symbol index associated with the DL RSCP.

10 . The TRP of claim 7 , wherein the first report further includes a line of sight (LoS) indicator or a non line of sight (NLOS) indicator.

11 . The TRP of claim 8 , wherein:

the transceiver is further configured to receive, from a second UE, an uplink (UL) sounding reference signal (SRS) for positioning,

the processor is further configured to perform a measurement for a UL RSCP based on the UL SRS, and

the UL RSCP is associated with a center frequency of the UL SRS.

12 . The TRP of claim 11 , wherein at least one of a relative time of arrival (RTOA), an UL SRS reference signal received power (RSRP), and an UL SRS reference signal received path power (RSRPP) is measured based on the UL SRS.

13 . A method of operating a user equipment (UE), the method comprising:

receiving, from a first transmit receive point (TRP), a first downlink (DL) position reference signal (PRS),

performing a measurement for the first DL PRS, and

transmitting, to the first TRP, a first report for the measurement,

wherein the first report includes a DL reference signal carrier phase (RSCP) associated with a center frequency for the DL PRS, and

wherein the DL RSCP is associated with a first path derived from first resource elements for carrying the DL PRS.

14 . The method of claim 13 , wherein the first report further includes at least one of a UE receive-transmit time difference, a DL PRS reference signal received power (RSRP), and a DL PRS reference signal received path power (RSRPP) of the DL PRS.

15 . The method of claim 13 , wherein the first report further includes a time stamp indicating a symbol index associated with the DL RSCP.

16 . The method of claim 13 , wherein the first report further includes a line of sight (LoS) indicator or a non line of sight (NLOS) indicator.

17 . The method of claim 13 , further comprising transmitting, to a second TRP, an uplink (UL) sounding reference signal (SRS) for positioning of an UL RSCP associated with a center frequency of the UL SRS wherein the first DL PRS has a continuous phase across symbols within a slot.

18 . The method of claim 17 , wherein;

the UL SRS is for the positioning of at least one of a relative time of arrival (RTOA), an UL SRS reference signal received power (RSRP), and an UL SRS reference signal received path power (RSRPP), and

the UL RSCP is associated with a second path derived from second resource elements for carrying the UL SRS.
