Abstract: Embodiments provide a service acceleration method, system, apparatus, and server in an NFV system. For achieving these, a programmable package determining entity in the NFV system can determine a target service function that needs to be accelerated. A target programmable package corresponding to the target service function that needs to be accelerated can be obtained and the target programmable package to an acceleration engine in a network functions virtualization infrastructure (NFVI) can be sent. The acceleration engine runs the target programmable package to accelerate the target service function that needs to be accelerated. A programmable package of the acceleration engine can thus be dynamically replaced, and a service diversity requirement can be met, thereby improving scalability of a service acceleration function.

Abstract: Embodiments of the present invention provide user equipment, including: a transceiver module, configured to receive configuration information, where the configuration information is used to configure at least one physical resource block (PRB) bundling size; and a processing module, configured to determine a precoding resource block group (PRG) size based on the at least one PRB bundling size. The embodiments of the present invention further provide an access device. In technical solutions provided in the embodiments of the present invention, the PRG size is configured by configuring the PRB bundling size.

Abstract: This application discloses a method for sending a demodulation reference signal, a method for receiving a demodulation reference signal, and a communication apparatus. The method for sending a demodulation reference signal includes: A network device generates a first signal and sends the first signal on a first time-frequency resource, where the first signal is formed by superimposing M DMRS port signals, and delay segmentation locations corresponding to at least two of the M DMRS port signals are different. Because the first signal is formed by superposing the M DMRS port signals, that is, the network device sends a plurality of DMRS port signals on a same time-frequency resource, reference signal overheads can be reduced. The network device sends more DMRS port signals on the same time-frequency resource. In this way, the network device can send more streams without increasing pilot overheads.
