Abstract
According to embodiments herein, assistance data may be provided to a UE regarding an anchor UE that provides a reference signal via the SL interface to the UE. Assistance data may include information indicative of the coordinates, height, drift rate, beam characteristics, group delay, and/or other aspects of the anchor UE. The assistance data may be provided to the UE by a location server, a base station, or directly from the anchor UE.
Claims35
A method of determining a location of a first user equipment (UE) using assistance data related to a second UE, the method comprising:
- obtaining assistance data related to determining the location of the first UE using a sidelink (SL) interface between the first UE and the second UE;
- and
- conducting a positioning operation at the first UE based at least in part on the assistance data, wherein the positioning operation comprises:
- transmitting a first positioning signal by the first UE via the SL interface, or
- performing, at the first UE, a measurement of a second positioning signal transmitted by the second UE via the SL interface.
A first user equipment (UE) for determining a location of the first UE a using assistance data related to a second UE, the first UE comprising:
- a transceiver;
- a memory;
- and
- one or more processors communicatively coupled with the transceiver and the memory, wherein the one or more processors are configured to:
- obtain the assistance data related to determining the location of the first UE using a sidelink (SL) interface between the first UE and the second UE;
- and
- conduct a positioning operation at the first UE based at least in part on the assistance data, wherein the positioning operation comprises:
- transmitting, with the transceiver, a first positioning signal by the first UE via the SL interface, or
- performing, with the transceiver, a measurement of a second positioning signal transmitted by the second UE via the SL interface.
An apparatus for determining a location of a first user equipment (UE) using assistance data related to a second UE, the apparatus comprising:
- means for obtaining assistance data related to determining the location of the first UE using a sidelink (SL) interface between the first UE and the second UE;
- and
- means for conducting a positioning operation at the first UE based at least in part on the assistance data, wherein the positioning operation comprises:
- means for transmitting a first positioning signal by the first UE via the SL interface, or
- means for performing, at the first UE, a measurement of a second positioning signal transmitted by the second UE via the SL interface.
A non-transitory computer-readable medium storing instructions for determining a location of a first user equipment (UE) using assistance data related to a second UE, the instructions comprising code for:
- obtaining assistance data related to determining the location of the first UE using a sidelink (SL) interface between the first UE and the second UE;
- and
- conducting a positioning operation at the first UE based at least in part on the assistance data, wherein the positioning operation comprises:
- transmitting a first positioning signal by the first UE via the SL interface, or
- performing, at the first UE, a measurement of a second positioning signal transmitted by the second UE via the SL interface.
