摘要： A phase shifter includes a cavity (100) and a first fixed transmission line (301), a second fixed transmission line (302), and a slidable transmission line (201) that are located in the cavity (100). The first fixed transmission line (301) is provided with a first open slot (3011), the second fixed transmission line (302) is provided with a second open slot (3021), and opening directions of the first open slot (3011) and the second open slot (3021) are opposite to each other. Two ends of the slidable transmission line (201) are respectively clamped in the first open slot (3011) and the second open slot (3021), so that the slidable transmission line (201) is electrically connected to the first fixed transmission line (301) and the second fixed transmission line (302). The slidable transmission line (201) slides relative to the first fixed transmission line (301) and the second fixed transmission line (302). In the phase shifter, the slidable transmission line and the fixed transmission lines can be coupled to each other effectively. The phase shifter has a simple structure, and has a low requirement for a transmission device.

摘要： Embodiments of the present invention disclose a codeword feedback method and a receiver, which relate to the field of communication technologies. The method includes: determining a precoding type used for downlink signal transmission, or receiving codebook indication signaling transmitted by a transmitter; selecting a codebook according to the precoding type, or selecting a codebook according to the codebook indication signaling; and selecting a codeword according to the codebook, and feeding back the codeword to the transmitter. The present invention can provide a new feedback mechanism for channel state information and a non-linear precoding codebook when needing to use both linear precoding and non-linear precoding, so that a communication system can select an appropriate precoding codebook to feed back state information according to different needs, thereby improving the performance of the communication system.

摘要： The embodiments of the present invention provide a tunnel fault detection method and a traffic engineering (TE) node. The method includes: receiving, by a traffic engineering TE node, a link fault report packet; determining, by the node, a faulty link in which a fault occurs according to the link fault report packet; detecting, by the node, whether one or more tunnels which use the node as an ingress node and pass through the faulty link exist; and identifying the tunnels as faulty tunnels if the one or more tunnels which use the node as the ingress node and pass through the faulty link exist. In the embodiments of the present invention, the TE node can detect all faulty tunnels at a time, and it is not necessary to wait until the fault notification based on each tunnel is received and then the faulty tunnel is identified one by one. Therefore, compared with the prior art, the present invention can detect the faulty tunnels in time in a network in which numerous tunnels are configured on a TE node.

摘要： Embodiments of the present invention provide a communication connection control method and a device. When a device finds that communication service quality provided by an optimal Wi-Fi access point is better than communication service quality provided by a currently connected Wi-Fi access point, the device automatically disconnects from the currently connected Wi-Fi access point, and initiates a connection request to the optimal Wi-Fi access point to obtain better communication service quality in a timely manner. This avoids a waste of network resources, and improves an intelligentization characteristic of human computer interaction of the device because user intervention of manual switch is not required.

摘要： In an active-active system, if write lock permission is granted to a second storage array, a first storage array sends to-be-written data and a lock revocation request together to a lock server; the lock server sends the lock revocation request carrying the to-be-written data to a second lock server; after storing the to-be-written data, the second lock server sends a lock revocation success message to the lock server; the lock server gives the write lock permission to the first storage array; and the first storage array obtains the write lock permission and stores the to-be-written data. By using the method, to-be-written data is stored in two storage arrays with relatively few procedures.
