Abstract: A phase-based ranging method and a related apparatus (50) are disclosed. The ranging method includes: receiving a first multi-tone signal sent by a second transceiver (70) (step S202), where the first multi-tone signal includes N first single-frequency signals, the N first single-frequency signals are signals obtained through negotiation between a first transceiver (60) and the second transceiver (70), and N is an integer greater than 1; performing down conversion on the first multi-tone signal based on each of the N first single-frequency signals to obtain N direct current DC signals (step S203), where each first single-frequency signal corresponds to one DC signal; and measuring a first phase of each of the N DC signals to obtain a first phase value sequence (step S204).

Abstract: The present disclosure relates to methods and apparatuses for sending a multi-tone signal. One example method includes generating a first multi-tone signal, and sending the first multi-tone signal. The first multi-tone signal includes N single-tone signals. Amplitude values of the single-tone signals are the same. Initial phases of at least two of the N single-tone signals are the same or absolute values of initial phases of at least two of the N single-tone signals are the same. N is an integer greater than or equal to 2.

Abstract: Embodiments of this application provide an upgrade method and apparatus, and an electronic device, and relate to the field of the Internet-of-vehicles technologies. The method includes: A server obtains a first instruction when a software function of an in-vehicle component is faulty, where the first instruction is used to indicate an upgrade strategy of the in-vehicle component, and the upgrade strategy is associated with a software function status of the in-vehicle component. The server sends task information of an upgrade task in response to the first instruction, where the task information includes information about the upgrade strategy, and the information about the upgrade strategy is used to indicate the in-vehicle component to be upgraded. Correspondingly, after receiving the task information of the upgrade task, a vehicle may upgrade the in-vehicle component based on the upgrade strategy.
