  • Publication number: 20240159563
    Abstract: In a method of generating an event map, a processing device obtains first information that indicates that there is an association relationship between a first event and a second event. The first information comprises association type information that indicates a type of the association relationship, and the first and second events are events in a map. The processing device then stores the first information as data of the map.

  • Publication number: 20240133711
    Abstract: Generating first map information, where the first map information includes information about a first reference object set, and the information about the first reference object set indicates a first identifier, in a geographic area, of each reference object in at least one reference object included in the first reference object set, and indicates a first position of each reference object in the at least one reference object. The first map information is generated, and the first map information indicates related information of each reference object in the first reference object set, to implement a manner of expressing the related information of the reference object more abundantly, so that maps provided by different map vendors may use reference objects in the first map information to perform position expression on an element or an event.

  • Publication number: 20240137082
    Abstract: A communication method and apparatus. A terminal device determines channel state information based on S indexes of S vectors. Each of the S vectors is included in a first vector quantization dictionary. The first vector quantization dictionary includes N1 vectors, where N1 and S are both positive integers. The terminal device sends the channel state information to a network device. Because a vector included in the vector quantization dictionary usually has a relatively large dimension, quantizing channel information by using the first vector quantization dictionary is equivalent to performing dimension expansion on the channel information or maintaining a relatively high dimension. High-precision feedback is implemented by using relatively low signaling overheads.

  • Patent number: 11353904
    Abstract: A voltage regulator system includes a switch system including a power switch to conduct an output current through an inductor based on an input voltage and a switching signal to generate an output voltage at a load. A feedback system generates a PWM signal based on the output voltage and based on a variable reference voltage. A gate driver system generates the switching signal based on the PWM signal. The gate driver system controls the switch system to increase the output voltage at output voltage slopes in each of startup stages during startup of the voltage regulator system. A sampling system samples the output current and the output voltage during the startup of the voltage regulator system to measure each slope of the output voltage slopes at each of the respective startup stages during the startup of the voltage regulator system.
