    Abstract: A packet processing method and apparatus are provided. The method includes: on a forwarding path of an IPv6 packet, a key node (for example, a firewall) signs a packet, and a downstream apparatus of the key node verifies the signature, to determine whether the packet passes through the key node in a forwarding process. According to this application, the key node performs checking, to effectively prevent a packet which packet header is modified by attackers from bypassing the key node.

    Abstract: This application discloses a method for obtaining a manufacturer usage description (MUD) file, a device, and a system. The method includes: A MUD control management device receives a MUD URL request message sent by a terminal device, and obtains at least one MUD file from a plurality of MUD file servers based on a target obtaining policy corresponding to the terminal device. Because the MUD control management device has target obtaining policies corresponding to terminal devices, the MUD control management device can obtain the MUD file from the plurality of MUD file servers based on the target obtaining policy corresponding to the terminal device. This provides a mechanism for obtaining a MUD file of a terminal device from a plurality of MUD file servers in a scenario in which a plurality of MUD files are distributed on the plurality of MUD file servers.

    Abstract: In a control channel resource transmission method, user equipment (UE) obtains a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter. The UE determines an antenna port according to the obtained configuration parameter, and then receives, through the antenna port, a control channel or a control channel element sent by the base station. The base station determines the antenna port according to the same configuration parameter as that of the user equipment, and sends, by using the antenna port, the control channel or the control channel element to the user equipment.

    Abstract: A method for determining a precoding matrix indicator, user equipment, and a base station are disclosed in embodiments of the present invention. The method includes: receiving a first reference signal set sent by a base station, where the first reference signal set is associated with a user equipment-specific matrix or matrix set; selecting a precoding matrix based on the first reference signal set, where the precoding matrix is a function of the user equipment-specific matrix or matrix set; and sending a precoding matrix indicator to the base station, where the precoding matrix indicator corresponds to the selected precoding matrix. In the embodiments of the present invention, CSI feedback precision can be improved without excessively increasing feedback overhead, thereby improving system performance.
