Abstract: A beam training method and a related device are disclosed. The method includes: sending, by a first communications device, sidelink control information (SCI) to a second communications device, where the SCI is used to instruct the first communications device to send at least one channel state information-reference signal (CSI-RS) to the second communications device; and sending, by the first communications device, the at least one CSI-RS to the second communications device based on the SCI, where the at least one CSI-RS is used by the second communications device to determine that a beam corresponding to a CSI-RS with highest signal strength in the at least one CSI-RS is a beam for communication between the second communications device and the first communications device. The CSI-RS used for beam training is dynamically sent based on the instruction of the SCI, and therefore, flexibility and efficiency of beam training are improved.

Abstract: Example oscillators and oscillator-based apparatus are described. One example oscillator includes: a resonant circuit, configured to generate an oscillator signal; a first cross-coupled transistor, coupled to the resonant circuit; and a power supply circuit, configured to supply a power supply signal for the first cross-coupled transistor based on a first voltage and a second voltage, where the first voltage is a power supply voltage, and the second voltage is a voltage generated by an external sensing circuit. Because an oscillation frequency of the oscillator changes with the power supply signal of the oscillator, the oscillation frequency of the oscillator can be compensated by adjusting the power supply signal.

Abstract: This application may be applied to an internet of vehicles, for example, V2X, LTE-V, and V2V. A first terminal device obtains a first time-frequency resource, where the first time-frequency resource is used to send sidelink control information and data. The first terminal device sends, on the first time-frequency resource, a sidelink reference signal, the sidelink control information, and the data to a second terminal device, where the sidelink reference signal is used to determine a channel status of a sidelink between the first terminal device and the second terminal device. According to the sidelink reference signal transmission method provided in this application, the sidelink reference signal is carried on the time-frequency resource used to send the sidelink control information and/or the data, and is sent together with the sidelink control information and/or the data.

Abstract: This application provides a sidelink control information sending method and a communications device. A method for sending unicast or multicast sidelink control information in V2X communication is provided. In the method, sidelink control information is divided into two parts. The first part includes resource indication information for transmitting sidelink data, and is scrambled by using a common sequence. The second part is sidelink control information other than the first part of sidelink control information, and is scrambled by using an identifier of a target communications device or a group identifier of a group to which the target communications device belongs. The target communications device can descramble the first part and the second part, and receive sidelink data in the V2X communication. Another communications device can descramble the first part obtain resource information, and can learn of resource occupation and reservation information when performing autonomous resource selection beyond network coverage.

Abstract: This application provides a resource determining method and an apparatus, to mitigate a resource conflict between an LTE-V2X apparatus and an NR-V2X apparatus. In the method, a terminal apparatus may obtain configuration information, first sidelink control information, and second sidelink control information. The first sidelink control information is control information used for E-UTRA radio access, and the second sidelink control information is control information used for NR radio access. The terminal apparatus determines an available time-frequency resource based on the first sidelink control information and the second sidelink control information. Based on the foregoing solution, the terminal apparatus can determine, in a resource pool based on the first sidelink control information and the second sidelink control information, a time-frequency resource that can be used by the terminal apparatus to send sidelink control information and data information, thereby mitigating the resource conflict between the LTE-V2X apparatus and the NR-V2X apparatus.
