Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the wireless communication device uses a fixed operational mode (e.g., equal-gain beamforming or co-phased space-time block coding), then the device complexity is reduced, but the adaptability to different channel conditions deteriorates
Solution Approach 1:
The patent implements dynamic adaptability by enabling the wireless communication device to switch between equal-gain beamforming and co-phased space-time block coding operational modes based on channel conditions. The system transforms phase-related information from one mode to another, allowing flexible adaptation without requiring separate fixed systems for each mode, thus resolving the contradiction between simplified structure and adaptability.
2Reliability
If the device switches between operational modes based on phase information staleness, then the communication quality is improved, but the processing complexity increases
Solution Approach 1:
The patent changes the parameter being monitored from complete channel state information to specifically phase-related information and its staleness. By focusing transformation processing only on phase parameters and triggering mode switching based on phase staleness rather than continuous full-channel analysis, the system improves communication quality while limiting processing complexity growth.
3Productivity
If the device uses equal-gain beamforming with phase information, then the data throughput is increased, but the performance consistency across varying channel conditions deteriorates
Solution Approach 1:
The system dynamically switches between equal-gain beamforming (which provides high throughput when phase information is fresh) and co-phased space-time block coding (which provides consistent performance when phase information is stale). This dynamic adaptation allows the system to maintain performance consistency across varying channel conditions while still achieving high data throughput when conditions permit.

AI summary
A communication device includes antennas to receive a first signal from a remote device, wherein the first signal corresponds to a first operational mode. A baseband processor selects either a first operational mode for transmitting a second signal or a second operational mode for transmitting the second signal. When the second operational mode is selected the baseband processor transforms the phase-related information corresponding to the first operational mode to transformed phase-related information corresponding to the second operational mode. The antennas transmit the second signal to the remote device in accordance with the transformed phase-related information corresponding to the second operational mode.
