Patent ID: 11546103

Abstract:
Disclosed are techniques for scheduling uplink (UL) and downlink (DL) physical layer resources for a serving node and a user equipment (UE) for round trip time (RTT) and observed time difference of arrival (OTDOA) based positioning. In an aspect, a serving node and/or a network entity configure the UL and DL physical layer resources, and inform the UE. A network node transmits RTT measurement (RTTM) signal to the UE and receives RTT response (RTTR) signals from the UE. The network node measures the times the RTTM signals are transmitted and the times the RTTR signals are received. The UE provides to serving node processing times indicating a duration between the UE receiving the RTTM signals and the UE transmitting the RTTR signals. The RTTs are calculated from the times measured by the network node and the processing times provided by the UE.
