Abstract

Disclosed are techniques for handling of radio frequency front-end group delays for round trip time estimation. In an aspect, a network entity determines a network total group delay and a user equipment determines a UE total GD. The network entity transmits one or more RTT measurement (RTTM) signals to the UE. Each RTTM signal includes a RTTM waveform. The UE determines one or more one or more RTT response (RTTR) payloads for one or more RTTR signals. Each RTTR signal also includes a RTTR waveform. The UE transmits the RTTR signal(s) to the network entity. For each RTTR signal, a transmission time of the RTTR waveform and / or the RTTR payload is / are determined based on the UE total GD. The network entity determines a RTT between the UE and the network entity based on the RTTM signal(s), the RTTR signal(s), and the network total GD.
