Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless communication systems operate in shared frequency bands, then spectrum utilization is improved, but interference from co-located-device systems increases
Solution Approach 1:
The patent introduces a frame structure as an intermediary carrier to transmit interference coordination information between wireless communication systems and co-located-device systems. This frame includes interference coordination operation information that enables the systems to coordinate their operations and reduce mutual interference while maintaining spectrum sharing.
Solution Approach 2:
The patent implements a feedback mechanism where interference coordination operation information is transmitted through frames, allowing receiving devices to provide feedback about interference conditions. This enables dynamic adjustment of transmission parameters to optimize spectrum utilization while managing interference from co-located devices.
2Adaptability or versatility
If interference coordination operation information is transmitted through frames, then interference coordination capability is improved, but communication overhead increases
Solution Approach 1:
The patent designs a universal frame structure that can carry multiple types of information including interference coordination operation information, resource allocation information, and acknowledgment information. This multi-functional frame reduces the need for separate dedicated frames for each type of information, thereby reducing overall communication overhead while maintaining comprehensive interference coordination capability.

AI summary
Provided are a wireless communication method and a communication device. The method comprises: on the basis of interference information, a first device sends a first frame to a second device, the first frame being used for indicating interference coordination operation information of one or more links and/or one or more subchannels/operating frequency bands. In the present application, the first device can send the first frame to the second device to indicate the interference coordination operation information of the one or more links and/or the one or more subchannels/operating frequency bands. On the basis of the interference coordination operation information, coordination of interference on the transmission link and/or the subchannel/operating frequency band is facilitated, thereby reducing the influence thereof on data transmission of a wireless communication system.
