    Abstract: A method for enhanced autonomous uplink timing adjustment includes determining that a user equipment (UE) is traveling above a predetermined velocity. In response to the determination that the UE is traveling above the predetermined velocity, a maximum aggregate adjustment rate to an uplink timing for the UE and a maximum amount of a magnitude of a timing change to the uplink timing for the UE are determined. The uplink timing for the UE is adjusted based on the maximum aggregate adjustment rate and the maximum amount of the magnitude of the timing change.

  • Publication number: 20240267875
    Abstract: A system and a method are disclosed for transmission of 5G side link positioning reference signals (SL-PRS) while in 5G side link mode 2 (for example, V2X). Using a shared resource pool and no data transmission, a UE determines three parameters (time, frequency, and PRS index) for transmission of a PRS using a comb structure. Using a dedicated resource pool with data transmission, the UE populates a time frequency grid for slot transmission so that PRS does not conflict with demodulation reference signals (DMRS).
