1. A method for supporting positioning measurements, comprising:
- designating a base station cell as a reference cell;
designating at least one other base station cell as a non-reference cell;
transmitting reference cell information and non-reference cell information to a wireless transmit/receive unit (WTRU) that makes the positioning measurements with respect to the reference cell and the non-reference cell, wherein the positioning measurements are used to determine a position of the WTRU; and
transmitting information for the non-reference cell that indicates that a transmission of a positioning reference signal (PRS) by the non-reference cell is synchronized with a transmission of a PRS by the reference cell.

10. A method for supporting positioning measurements at a wireless device, comprising:
-
receiving reference cell information associated with a reference cell from a network, wherein the reference cell corresponds to a base station cell; receiving non-reference cell information associated with a non-reference cell, wherein the non-reference cell corresponds to one other base station cell; receiving information for the non-reference cell that indicates that a transmission of a positioning reference signal (PRS) by the non-reference cell is synchronized with a transmission of a PRS by the reference cell; and making positioning measurements using the reference cell information and the non-reference cell information, wherein the positioning measurements are used to determine a position of the wireless device. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A wireless device, comprising:
-
a receiver configured to receive reference cell information associated with a reference cell from a network, wherein the reference cell corresponds to a base station cell; the receiver configured to receive non-reference cell information associated with a non-reference cell, wherein the non-reference cell corresponds to one other base station cell; a processor in communication with the receiver; a transmitter in communication with the processor; the processor configured to make positioning measurements using the reference cell information and the non-reference cell information; the processor further configured to use the positioning measurements to determine a position of the wireless device; and the receiver further configured to receive information for the non-reference cell that indicates that a transmission of a positioning reference signal (PRS) by the non-reference cell is synchronized with a transmission of a PRS by the reference cell. - View Dependent Claims (18, 19)
