Abstract
Disclosed are techniques for communication. In an aspect, a reference device (e.g., gNB or BS) and a BS obtain a configuration of a TDOA procedure including respective PRSs to be transmitted by the reference device and the BS. In an aspect, the reference device and the BS each mute their own transmission while the other device is transmitting its respective PRS. Other aspects are directed to DL-TDOA, UL-TDOA and elliptical positioning techniques.
Claims19
A method of operating a network component, comprising:
- obtaining a configuration of a time difference of arrival (TDOA) procedure that comprises a first positioning reference signal (PRS) for transmission by the network component to a target user equipment (UE) during a first time period and a second PRS for transmission by a reference device with a known location to the target UE during a second time period, the first time period and the second time period being separated from each other by a time gap;
- transmitting the first PRS to the target UE during the first time period;
- and
- muting transmission during the second time period.
