Abstract: A method for authentication and related devices includes obtaining a first session key BS1 generated according to a set X and a set Y. The set X is a set of samples of received signal strength indicators (RSSIs) of a wireless channel of a user equipment (UE), and the set Y is a set of samples of RSSIs of a wireless channel of a vehicle. Upon receiving a second message from the UE, wherein the second message is hashed by a second session key BS2, extracting the second session key BS2 from the second message. When the first session key BS1 is the same as the second session key BS2, the authentication between the UE and the vehicle is successful.

Abstract: A data storage method applying to a phase change memory and the phase change memory are provided. After obtaining to-be-stored data, the phase change memory (PCM) generates an erase pulse signal and a write pulse signal according to the to-be-stored data. The to-be-stored data is multi-bit data. The write pulse signal includes at least two contiguous pulses. Intervals between the at least two contiguous pulses are the same. The intervals between the at least two contiguous pulses have a value determined according to the to-be-stored data. The PCM applies the erase pulse signal to a storage unit of the PCM to enable the storage unit to change to a crystalline state. Further, the write pulse signal is applied to the storage unit to enable the storage unit to change to an amorphous state corresponding to a first resistance value, where the amorphous state represents the to-be-stored data.

Abstract: A data storage method applying to the phase change memory and a phase change memory are provided. After obtaining to-be-stored data, the phase change memory generates an erase pulse signal and a write pulse signal according to the to-be-stored data. The to-be-stored data is multi-bit data. The write pulse signal is a signal including at least two consecutive pulses with a same amplitude. The amplitude of the at least two consecutive pulses is a value determined according to the to-be-stored data. Then, the phase change memory applies the erase pulse signal to a storage unit of the phase change memory to allow the storage unit to switch to a crystalline state. Further, the write pulse signal is applied to the storage unit to allow the storage unit to switch to an amorphous state corresponding to a first resistance value, where the amorphous state represents the to-be-stored data.

Abstract: The present invention discloses a power control method, apparatus, and system. The power control method of the present invention includes: when a service runs in a first-standard communication system, determining a transmit power P1 of the first-standard communication system; determining that the transmit power P1 is higher than or equal to a threshold value P2 of power interference of the first-standard communication system to a second-standard communication system; use a power lower than P1 to send data on an interference frequency of the first-standard communication system. According to the power control method in the present invention, a signal transmit power of the interfering frequency of the first-standard communication system can be reduced when it is determined that the first-standard communication system will cause interference to the second-standard communication system, thereby reducing the interference of the first-standard communication system to the second-standard communication system.
