Abstract
A method, a user communication device, and a base station are disclosed. A transceiver 302 may receive a serving transmission from a serving base station. A processor 304 may make a status determination of an autonomous muting status of a neighbor base station based on the serving transmission.
Claims2
A method for measuring a time difference of arrival measurement in a mobile device, comprising:
- receiving a muting status indication in a position assistance data from a serving base station, wherein the position assistance data includes at least a physical cell identifier corresponding to a neighbor base station, a muting status applicable to a positioning reference signal transmission from the neighbor base station, and a neighbor cell search offset applicable to a positioning reference signal transmission from the neighbor base station;
- making a status determination of a muting status of a neighbor base station, where the status determination includes inferring that the muting status is inactive based on the received muting status indication;
- receiving a positioning reference signal transmitted from the neighbor base station;
- and
- determining a time difference of arrival of the neighbor base station transmission based on the received positioning reference signal and based on the muting status.
2 more elements
An apparatus for measuring a time difference of arrival measurement in a mobile equipment, comprising:
- a receiver that receives a muting status indication in a positioning assistance data from a serving base station, wherein the positioning assistance data includes at least a physical cell identifier corresponding to a neighbor base station, a muting status applicable to a positioning reference signal transmission from the neighbor base station, and a neighbor cell search offset applicable to a positioning reference signal transmission from the neighbor base station;
- and
- a processor coupled to the receiver, the processor configured to make a status determination of a muting status of a neighbor base station, where the status determination includes inferring that the muting status is inactive based on the received muting status indication,
- wherein the receiver is further configured to receive a positioning reference signal transmitted from the neighbor base station;
- and
- wherein the processor is further configured to determine a time difference of arrival of the neighbor base station transmission based on the received positioning reference signal and the muting status.
