Abstract: A low power consumption method for C-V2X, an electronic device, and a chip system are provided. The method is applied to a first electronic device, and the first electronic device supports a C-V2X function. The method includes, when it is determined that the first electronic device is at a target location, activating the C-V2X function of the first electronic device. The first electronic device performs data exchange with a second electronic device based on the C-V2X protocol. When it is determined that the first electronic device completes data exchange with the second electronic device, the C-V2X function of the first electronic device is deactivated.

Abstract: A beam selection method and a communication apparatus are provided, which relate to the field of communication technologies. The method includes: A terminal receives a downlink reference signal from a third beam of a network device on a first beam and a second beam; then, the terminal performs RSRP measurement and MPE measurement on the first beam and the second beam separately to obtain first RSRP, second RSRP, first back-off power, and second back-off power; and when a difference between the first RSRP and the first back-off power is greater than a difference between the second RSRP and the first back-off power, the terminal sends uplink data by using the first beam. In this technical solution, the terminal may select an uplink working beam with reference to the measured back-off power of the first beam and the measured back-off power of the second beam.

Abstract: Embodiments of this application provide an uplink resource pre-application method and a related device. An electronic device may predict encoding duration of a to-be-sent data packet in an application (APP), determine an encoding completion moment of the to-be-sent data packet, and send an uplink scheduling request to a network device before the encoding completion moment of the to-be-sent data packet, to apply for an uplink resource for the to-be-sent data packet in advance. In this way, a latency of sending uplink data by the electronic device may be reduced, and power consumption of the electronic device may be reduced.

Abstract: A cell selection method, related to the communications field, includes a terminal device sending a first request to a network device, where the first request is used to request to select a serving cell for the terminal device in an energy efficiency first manner. The terminal device sends first information to the network device, where the first information is used by the network device to select a cell in a first communications system or a cell in a second communications system for the terminal device. The terminal device receives configuration information of a serving cell from the network device, where the serving cell is selected by the network device from the cell in the first communications system or the cell in the second communications system in a manner that energy efficiency of the terminal device is first.
