Section: 6.5.1G Frequency error for V2X Communication
Content: The UE modulated carrier frequency for V2X sidelink transmissions shall be accurate to within ±0.1 PPM observed over a period of one time slot (0.5 ms) compared to the absolute frequency in case of using GNSS synchronization source. The same requirements applied over a period of one time slot (0.5 ms) compared to the relative frequency in case of using the E-UTRA Node B or V2X UE sidelink synchronization signals. When UE is configured for simultaneous E-UTRA V2X sidelink and E-UTRA uplink transmissions for inter-band E-UTRA V2X / E-UTRA bands specified in Table 5.5G-2, the requirements in subclause 6.5.1G apply for V2X sidelink transmission and the requirements in subclause 6.5.1 apply for the E-UTRA uplink transmission. For V2X UE supporting Transmit Diversity, if the UE transmits on two antenna connectors at the same time, the UE modulated carrier frequency at each transmit antenna connector shall be accurate to within ±0.1 PPM observed over a period of one time slot (0.5 ms) in case of using GNSS synchronization source. The same requirements applied over a period of one time slot (0.5 ms) compared to the relative frequency in case of using the E-UTRA Node B or V2X UE sidelink synchronization signals. If the UE transmits on one antenna connector at a time, the requirements for single carrier shall apply to the active antenna connector.
