Engineering Contradiction Analysis
1Productivity
If full duplex technology is applied in cellular networking, then spectral efficiency is improved, but interference problems occur
Solution Approach 1:
The terminal device performs preliminary measurement and recording of full duplex information before establishing a connection with the network device. This preliminary action allows the terminal to have ready the necessary information about interference characteristics, enabling the network to configure appropriate communication modes without causing harmful interference while maintaining high spectral efficiency.
2Productivity
If full duplex technology is applied in cellular networking, then spectral efficiency is improved, but communication stability deteriorates
Solution Approach 1:
The terminal device provides feedback information about recorded full duplex characteristics to the network device during connection establishment. This feedback mechanism enables the network to adjust communication parameters based on actual interference conditions, maintaining both high spectral efficiency and communication stability through continuous adaptation.
3Productivity
If network devices configure full duplex communication modes, then spectral efficiency is improved, but device complexity increases
Solution Approach 1:
The terminal device autonomously performs measurement and recording of full duplex information, and automatically provides this information to the network device during connection establishment. This self-service approach reduces the network device's configuration complexity by eliminating the need for manual measurement and analysis, while still enabling optimized spectral efficiency.

AI summary
An information acquisition method, applied to a network device is provided. The method includes receiving first indication information sent by a first terminal device, in which the first indication information is configured to indicate to the network device that the first terminal device has recorded full duplex information. The recorded full duplex information may be information about the network device supporting a full duplex communication, which is measured and recorded based on a configuration requirement of the network device when the first terminal device is in an idle state.
