Abstract: A DC/DC power converter converts voltage at an input of the DC/DC power converter to a voltage at an output of the DC/DC power converter, where the output voltage is a multiple of the input voltage. The DC/DC power converter comprises two switching circuits electrically connected in series, two capacitors electrically connected in series, and a resonant circuit comprising a resonant capacitor and a resonant inductor. The series connection of the two capacitors is electrically connected in parallel to the series connection of the two switching circuits. The resonant circuit is electrically connected to the two switching circuits. A first capacitor of the two capacitors is electrically connected in parallel to the input. Each switching circuit comprises two switching units electrically connected in series, wherein each switching unit comprises two or more switches electrically connected in series.

Abstract: A method includes: A second node sends a prior distribution of a parameter in a federated model to at least one first node. After receiving the prior distribution of the parameter in the federated model, the at least one first node performs training based on the prior distribution of the parameter in the federated model and local training data of the first node, to obtain a posterior distribution of a parameter in a local model of the first node. After the local training ends, the at least one first node feeds back the posterior distribution of the parameter in the local model to the second node, so that the second node updates the prior distribution of the parameter in the federated model based on the posterior distribution of the parameter in the local model of the at least one first node.

Abstract: Embodiments of this application provide a communication method and apparatus. The method includes: A first terminal performs integrity protection verification on a received RRC message; and when the integrity protection verification fails, an RRC layer of the first terminal sends a first indication and an identifier of a second terminal to an application layer of the first terminal, where the first indication and the identifier of the second terminal are used by the application layer to disconnect a unicast connection between the first terminal and the second terminal. Based on this solution, when the integrity protection verification performed by the first terminal on the received message fails, the RRC layer of the first terminal may report the first indication and the identifier of the second terminal to the application layer, to trigger the application layer to disconnect the unicast connection between the first terminal and the second terminal.

Abstract: The application provides method for communicating channel state information (CSI) in a communication network. The method is as follows: An apparatus determines whether a length of CSI is less than a preset length; and adds a padding bit to the CSI when determining that the length of the CSI is less than the preset length, where a length of CSI obtained by adding the padding bit is consistent with the predetermined length. The CSI obtained by adding the padding bit is communicated in the communication network.
