A method for switching signal processing modes in network devices, allowing them to transition between a base station mode with strong signal processing capabilities and a relay mode with reduced processing capabilities, thereby optimizing energy consumption and service performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the network device shuts down the radio frequency channel for energy saving, then energy saving gain is improved, but service performance deteriorates due to loss of emergency service capabilities
Solution Approach 1:
The network device dynamically switches between base station mode and relay mode based on service requirements. In base station mode, the device performs full signal processing including baseband processing for emergency services. In relay mode, the device performs only radio frequency signal processing for normal services, achieving energy saving while maintaining service performance through dynamic adaptation.
2Reliability
If the base station performs full signal processing including baseband processing, then service performance is improved, but power consumption increases
Solution Approach 1:
The base station performs only the necessary portion of signal processing based on operational mode. In relay mode, it performs partial signal processing (radio frequency processing only) without excessive baseband processing, reducing power consumption while still fulfilling relay functionality. In base station mode, it performs full signal processing when needed for emergency services.
3Adaptability or versatility
If the network device switches between base station mode and relay mode, then adaptability is improved, but device complexity increases
Solution Approach 1:
The signal processing functionality is segmented into distinct modules: radio frequency signal processing module and baseband signal processing module. The switching module can selectively activate or deactivate these modules based on operational mode, reducing overall device complexity by allowing individual modules to be simplified or removed depending on the chosen mode rather than requiring full functionality in all modes.

AI summary
A method for switching a signal processing mode is provided. The method includes: A signal processing mode of a network device includes a first mode and a second mode. Processing, by the network device, a signal in the first mode includes processing a baseband signal of the signal; and processing, by the network device, the signal in the second mode includes amplifying and forwarding a radio frequency signal of the signal but does not include processing the baseband signal of the signal. A plurality of signal processing modes of the network device are configured, to enable the signal processing modes of the network device to better adapt to different communication scenarios, balancing an energy saving gain and service performance of the network device.
