Abstract: Method and apparatus for optimizing the reporting of Uu-RTT or SL-RTT measurements. The apparatus determines a RX-RS-TX-RS proximity parameter defining a proximity window around the RX-RS resource for receiving the RX-RS. The apparatus identifies a TX-RS resource of at least one TX-RS resource for transmitting TX-RS within a proximity window around a RX-RS resource for receiving RX-RS. An identified TX-RS resource being used by the UE for determining a UE RX-TX time difference associated with a time difference between reception of the RX-RS and transmission of the TX-RS. The apparatus measures the UE RX-TX time difference based on received RX-RS in the RX-RS resource and transmitted TX-RS in the identified TX-RS resource when TX-RS is transmitted in the identified TX-RS resource.
