## Abstract

A method of handling positioning measurement for a relay in a wireless communications system is disclosed. The method comprises communicating with a mobile device and a base station to serve the mobile device for conveying signaling between the mobile device and the base station, and transmitting a first reference signal associated with a positioning measurement to the mobile device.

## Claims

### Claim 1

A method of handling measurement for a mobile device in a wireless communications system, the method comprising:
activating a measurement;
measuring cell state information reference signals (CSI-RS) or cell reference signals (CRS) from a plurality of cells associated with a coordinated multipoint transmission/reception (COMP) operation and configured for the mobile device or for a CoMP measurement;
generating a measurement report including measurement result of measuring at least one of the CSI-RS and the CRS of each measured cell in the measurement report for each measured cell in the measurement report; and
including a second indication for indicating a type of each of the measured reference signals, in the measurement report so that the network identifies the type of each of the measured reference signals with the indication.

### Claim 2 (depends on 1)

The method of claim 1, further comprising
sending the measurement report to a donor serving cell of the plurality of cells, wherein the donor serving cell is controlled by a donor base station which configures the plurality of cells associated with the COMP operation to the mobile device; or
sending the measurement report to at least one of the plurality of cells associated with the COMP operation, or
sending separated measurement reports to corresponding measured cells of the plurality of cells associated with the COMP operation.

### Claim 3 (depends on 1)

The method of claim 1, wherein measuring the CSI-RSs or the CRSs from the plurality of cells associated with the COMP operation and configured for the mobile device or for COMP measurement comprises:
for each of the plurality of cells, automatically determining whether to measure the CSI-RS or the CRS or whether to report the measurement of the CSI-RS or the CRS; or
determining whether to measure the CSI-RS or the CRS or whether to report the measurement of the CSI-RS or the CRS according to a first indication received from the donor serving cell.

### Claim 4 (depends on 1)

The method of claim 1, wherein the network identifies the type of each of the measured reference signals with the indication, and then applies a power control procedure for the reference signal type being measured according to the indication.

### Claim 5 (depends on 4)

The method of claim 4, wherein the power control procedure comprises different power control steps or offsets for the measured reference signals of different types, and the power control steps or offset for the measured reference signals of different types are configured dynamically or semi-statically.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
including a physical cell identity (PCI) or a cell global identity (CGI) of each of the plurality of cells in the measurement report.
