This application provides a method and an apparatus for updating a timing offset, and is particularly applicable to an NTN network such as satellite communication. The terminal side method includes: A terminal receives a timing offset difference ΔKoffset, and updates a timing offset based on the ΔKoffset to obtain an updated timing offset. The network side method includes: A network device determines a timing offset difference ΔKoffset, and sends the ΔKoffset to a terminal device, wherein the ΔKoffset is used for the terminal device to update a timing offset.

A network performance detection method and apparatus, and a related network device are disclosed. According to the network performance detection method, a first IFIT header includes reporting manner indication information indicating that reporting is performed by an egress node device. After obtaining a first IFIT detection packet including the first IFIT header, a first network device can provide and process a second IFIT detection packet, where the second IFIT detection packet is obtained by adding a first device identifier and a first data flow detection result to the first IFIT detection packet. In other words, a detection result obtained by detecting a first data flow is reported only by the egress node device, and all node devices on a transmission link of the first data flow each includes the detection result in a same IFIT detection packet and sends the same IFIT detection packet to the egress node device.

A channel state information measurement method includes receiving, by a terminal device, configuration information from a network device. The configuration information includes first indication information and second indication information. The first indication information indicates K channel measurement signal resources, K is greater than or equal to 2, the second indication information indicates the terminal device is to measure aggregated channel state information (CSI) based on N channel measurement signal resources, and N is less than or equal to K. The method also includes measuring, by the terminal device, the N channel measurement signal resources based on the configuration information. The method further includes obtaining, by the terminal device, the aggregated CSI through calculation based on N measurement results. The aggregated CSI is CSI of M antenna ports, and M is a sum of quantities of antenna ports of the N channel measurement signal resources.
