The invention provides a 5G network slice + BWP-based radio frequency remote unit, which is characterized by comprising a digital processing unit, a radio frequency small signal unit, a power amplification (PA) unit, a low noise amplifier (LNA) unit, a radio frequency filter unit, a power supply unit and a shell, the radio frequency small signal unit is connected with the digital processing unit, connected with the radio frequency filter unit through the power amplification PA unit and connected with the low noise amplifier LNA unit, the power supply unit provides power, the power supply unit is arranged in the shell and supplies power through a photoelectric hybrid cable, and the shell is internally or externally provided with an antenna. According to the invention, the 5G network slice and the 5G BWP are combined, end-to-end distribution of the 5G network is realized, a more flexible network adaptation mode and differentiated service are matched for application expansion of the 5G enabling vertical industry, flexible transmission bandwidth configuration of a network side and a UE side is realized, and smooth operation of an NR system is possible.
Description
technical field [0001] The present invention relates to the field of network topology, in particular to a radio frequency remote unit based on 5G network slicing+BWP. Background technique [0002] In the 5G era, different services have diverse network requirements. In order to adapt to the needs of different services, the concept of supporting end-to-end slicing is proposed in the 5G network. End-to-end network slicing can provide differentiated virtual networks in terms of delay, security, mobility, and transmission rate in different application scenarios. From another perspective, network slicing technology can virtualize network hardware resources Then, based on different business requirements, virtualized network resources are reorganized on demand to form multiple logical networks that are isolated from each other to provide efficient network services for different business scenarios. According to the current industry consensus on network slicing, network slicing has ...
