Abstract: Systems and methods of bidirectional timing measurement are provided. In some embodiments, a method performed by a User Equipment (UE) includes: receiving a configuration for performing a bidirectional timing measurement on one or more cells; adapting the bidirectional timing measurement procedure based on one or more conditions or relations or criteria; and using the adapted procedure for performing the configured bidirectional timing measurement. The bidirectional timing measurement can be a UE Receive-Transmit (Rx-Tx) time difference. The measurement adaption can include: whether the cell for the bidirectional timing measurement is the Downlink reference cell for a Sounding Reference Signal (SRS) for the UE. In this way, the bidirectional timing measurement performance is enhanced. The UE only discards bidirectional timing measurement (e.g., UE Rx-Tx time difference) when the UE autonomous timing adjustment will make the measurement inaccurate.
