1. A method of a network entity, the method comprising:
determining information indicating a network total group delay (GD) comprising a network transmission GD and a network reception GD,
the network transmission GD indicating a time interval between a measured transmission time of a network Tx signal transmitted from the network entity and an actual transmission time of the network Tx signal leaving the network entity, and
the network reception GD indicating a time interval between an actual arrival time of a network Rx signal at the network entity and a measured arrival time of the network Rx signal at the network entity;
transmitting, to a user equipment (UE), one or more round trip time (RTT) measurement (RTTM) signals on RTTM resources comprising downlink (DL) physical layer resources, each RTTM signal comprising an RTTM waveform;
receiving, from the UE, one or more RTT response (RTTR) signals on RTTR resources comprising uplink (UL) physical layer resources, each RTTR signal corresponding to one or more of the RTTM signals and comprising an RTTR waveform and an RTTR payload; and
determining an RTT between the UE and the network entity based on the RTTM signal(s), the RTTR signal(s), and the information indicating the network total GD.
