Abstract: A first node device includes a transmitter, a receiver, a processor, and a non-transitory computer-readable storage medium storing a program to be executed by the processor. The program includes instructions to cause the transmitter to send, to a second node device, an offset of a first uplink sending timing of the second node device and a first amount of timing adjustment of the second node device, cause the transmitter to send indication information to the second node device, where the indication information indicates whether the second node device sends uplink data by using the first uplink sending timing of the second node device, and receive, through the receiver, data sent by the second node device, where the first node device is a parent node device of the second node device.

Abstract: This application provides an information transmission method and an apparatus and relates to the field of communications technologies, to resolve a problem of power waste caused when a communications device blindly monitors downlink control information in all monitoring occasions. The method includes: determining, by a communications device, information about a target beam; determining a target monitoring occasion based on the information about the target beam and a mapping relationship between information about a beam and a monitoring occasion, where the target monitoring occasion is in a system information window, and the system information window is used for OSI; and monitoring downlink control information in the target monitoring occasion.

Abstract: A patch-upgrade-based file processing method includes receiving a file access request, where the file access request includes storage path information, determining whether the storage path information exists in an association relationship is between original file path information and patch upgrade file path information when the storage path information indicates a first partition, querying the association relationship to obtain patch upgrade file path information corresponding to the storage path information when the storage path information exists in the association relationship between the original file path information and the patch upgrade file path information, and obtaining, from a target partition indicated by the patch upgrade file path information, a patch upgrade matching the patch upgrade file path information.

Abstract: 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).

Abstract: An FBMC signal transmitting method and receiving method, a transmitter, and a receiver are provided. The transmitting method includes: generating offset quadrature amplitude modulation OQAM symbols included on at least two subbands; mapping an OQAM symbol on each subband onto a respective subcarrier to obtain a frequency-domain signal, where a first frequency interval exists between adjacent subcarriers in a same subband, a second frequency interval exists between adjacent subcarriers that belong to two adjacent subbands, the second frequency interval is a sum of the first frequency interval and a guard band interval, and the guard band interval is a fractional multiple of the first frequency interval; generating an FBMC signal out of the frequency-domain signal; and transmitting the FBMC signal to a receiver.

Abstract: 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 a lock revocation request carrying the to-be-written data to the second storage array; after storing the to-be-written data, the second storage array 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.
