FIG. 11 illustrates an exemplary method 1100 performed by the UE (such as the UE 102) in determining the RTT. At 1110, the UE may provide a UE capability report to the network entity. For example, the UE may report its measurement capabilities (e.g., types of measurements, accuracy of measurements (e.g., accuracy of group delay measurements), MIMO capacity, FDD capability, and so on. At 1120, the UE may determine a UE total GD, which comprises a UE transmission GD and a UE reception GD. The UE transmission GD indicates a time interval between a measured transmission time of a UE Tx signal (e.g., RTTR signal) transmitted from the UE and an actual transmission time of the UE Tx signal leaving the UE. The UE reception GD indicates a time interval between an actual arrival time of a UE Rx signal (e.g., RTTM signal) at the UE and a measured arrival time of the UE Rx signal at the UE.
FIG. 12 illustrates an example process performed to implement block 1120, i.e., determine the UE total GD. At 1210, the UE may request to the network entity scheduling of self-transmit and self-receive resources to be allocated for Tx and Rx antennas of the UE. The network entity may schedule the resources at 1220 and may notify the UE at 1230. The network entity may take into account the UE capabilities received at 1110 when scheduling the resources. The self-transmit resources may comprise physical layer resources, and the self-receive resources may also comprise physical layer resources. The resources may be scheduled such that there will be minimal interferences to the UE.
