摘要： This application provides a communication method and a related device. The communication method includes: A network device receives a measurement report from a terminal in a single-signaling connected state. The network device determines, based on the measurement report, whether to release a communication connection to the terminal in the single-signaling connected state. According to this application, the terminal in the single-signaling connected state is released at a proper occasion. In this way, it can be ensured that a terminal that cannot continue to receive a service of a current serving cell is released in time, thereby mitigating service impact caused because handover cannot be performed in time. In addition, it can be further ensured that a terminal that can normally receive the service of the current serving cell is not released in advance, thereby reducing system overheads and shortening an access delay.

摘要： This application provides a method for configuring a transmit port of a downlink reference signal and a communication apparatus. A network device indicates, to a terminal device by using first indication information, configurations corresponding to a plurality of transmit ports. Each transmit port may be associated with one piece of delay information, transmit ports associated with same delay information correspond to a same configuration, and at least two transmit ports associated with different delay information correspond to different configurations. The configuration includes one or more of a precoding resource bundling granularity, a subband size, and a pilot density. The network device may select a proper configuration based on different delay information, for example, may use different resource bundling granularities and/or different pilot densities. The terminal device may receive, based on a configuration corresponding to each port, downlink reference signals sent by the plurality of transmit ports. A channel estimated by the terminal device based on this is more accurate, thereby facilitating obtaining a more accurate channel measurement result and improving system performance.

摘要： This application provides a channel measurement method and a communication apparatus. The method may include: A terminal device receives a precoded reference signal and indication information, where the indication information is used to indicate a relative delay between a first delay and a second delay, and the first delay and the second delay are determined through uplink channel measurement; and the terminal device performs channel measurement based on the precoded reference signal and the indication information. According to this application, a relative delay between a plurality of delays is indicated, so that impact of a delay deviation caused by an uplink and downlink timing error can be reduced when channel estimation is performed based on an idea of partial reciprocity.

摘要： Embodiments of the present invention provide a service acceleration method, system, apparatus, and server in an NFV system, so as to improve scalability of a service acceleration function in the NFV system. The method in the embodiments of the present invention includes: determining, by a programmable package determining entity in the NFV system, a target service function that needs to be accelerated; obtaining a target programmable package corresponding to the target service function that needs to be accelerated; and sending the target programmable package to an acceleration engine in a network functions virtualization infrastructure (NFVI). The acceleration engine runs the target programmable package to accelerate the target service function that needs to be accelerated. In the embodiments of the present invention, a programmable package used for service acceleration is not a fixed programmable package pre-installed in the acceleration engine, but is a programmable package dynamically determined based on a service function that needs to be accelerated currently. Therefore, a programmable package of the acceleration engine can be dynamically replaced, and a service diversity requirement can be met, thereby improving scalability of a service acceleration function in the NFV system.
