## Abstract

Techniques are described to for carrier phase measurements for wireless communication. An example wireless communication method includes receiving, by a wireless device from a network device, configuration information of a reference signal; performing, by the wireless device, a carrier phase measurement of a carrier that includes the reference signal; and sending, by wireless device, a measurement report comprising a result of the carrier phase measurement of the carrier that includes the reference signal.

## Claims

### Claim 1

A wireless communication method, comprising:
receiving, by a wireless device from a network device, configuration information of a reference signal;
performing, by the wireless device, a carrier phase measurement of a carrier that includes the reference signal; and
sending, by wireless device, a measurement report comprising a result of the carrier phase measurement of the carrier and a time difference of arrival (TDOA) measurement of the carrier, wherein the carrier includes the reference signal, wherein a reference point used in a timing differential-based positioning technique is same as that used in the carrier phase measurement, wherein the reference point is a reference transmission reception point (TRP).

### Claim 2 (depends on 1)

The method of claim 1, wherein the carrier phase measurement is performed along with a timing based measurement over a same measurement period.

### Claim 3 (depends on 1)

The method of claim 1, wherein the timing differential-based positioning technique is a reference signal time difference (RSTD).

### Claim 4

An apparatus for wireless communication comprising at least one processor, configured to implement a method that causes the apparatus to:
receive, by a wireless device from a network device, configuration information of a reference signal;
perform, by the wireless device, a carrier phase measurement of a carrier that includes the reference signal; and
send, by wireless device, a measurement report comprising a result of the carrier phase measurement of the carrier and a time difference of arrival (TDOA) measurement of the carrier, wherein the carrier includes the reference signal, wherein a reference point used in a timing differential-based positioning technique is same as that used in the carrier phase measurement, wherein the reference point is a reference transmission reception point (TRP).

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the carrier phase measurement is performed along with a timing based measurement over a same measurement period.

### Claim 6 (depends on 4)

The apparatus of claim 4, wherein the timing differential-based positioning technique is a reference signal time difference (RSTD).

### Claim 7

A non-transitory computer readable program storage medium having code stored thereon, the code, when executed by at least one processor of an apparatus, causes the apparatus to implement a method, comprising:
receiving, by a wireless device from a network device, configuration information of a reference signal;
performing, by the wireless device, a carrier phase measurement of a carrier that includes the reference signal; and
sending, by wireless device, a measurement report comprising a result of the carrier phase measurement of the carrier and a time difference of arrival (TDOA) measurement of the carrier, wherein the carrier includes the reference signal, wherein a reference point used in a timing differential-based positioning technique is same as that used in the carrier phase measurement, wherein the reference point is a reference transmission reception point (TRP).

### Claim 8 (depends on 7)

The non-transitory computer readable program storage medium of claim 7, wherein the carrier phase measurement is performed along with a timing based measurement over a same measurement period.

### Claim 9 (depends on 7)

The non-transitory computer readable program storage medium of claim 7, wherein the timing differential-based positioning technique is a reference signal time difference (RSTD).
