Abstract
Methods and apparatuses for round-trip carrier-phase operation in a wireless communication system. A method of operating a user equipment (UE) includes receiving, from a first transmit receive point (TRP), a first downlink (DL) position reference signal (PRS) and measuring a first carrier phase associated with a center frequency of the first DL PRS. The method further includes including, in a measurement report, (i) a carrier phase measurement based on the measurement of the first carrier phase and (ii) a DL reference signal time difference (RSTD) measurement or a UE receive-transmit time difference measurement and transmitting the measurement report.
Claims18
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.
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.
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.
