Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If beamforming operations are configured based on worst-case or minimum-capability assumptions, then all devices can be supported, but resource efficiency deteriorates and network performance is suboptimal
Solution Approach 1:
The patent changes the parameter of beamforming configuration from fixed worst-case assumptions to dynamic configurations based on actual device capabilities. The network node receives capability information from the device and adjusts beamforming parameters (such as number of beams, beam widths, sweeping ranges) accordingly, transforming the system from a static to a parameter-adaptive state that optimizes resource usage.
Solution Approach 2:
The patent introduces dynamics into the beamforming configuration process by making it responsive to real-time device capability information. Instead of using static conservative configurations, the system dynamically adapts beamforming settings based on the specific capabilities of each device, allowing optimal resource allocation while maintaining support for diverse device types.
2Adaptability or versatility
If beamforming operations are configured based on worst-case or minimum-capability assumptions, then compatibility with all devices is ensured, but network performance deteriorates
Solution Approach 1:
The patent transforms beamforming configuration from a fixed conservative setting to a dynamic parameter set based on actual device capabilities. By receiving capability information from devices and adjusting parameters such as beam count, beam width, and sweeping range, the system achieves both high device capability utilization and optimal network performance.
Solution Approach 2:
The patent implements a feedback mechanism where devices transmit their beamforming capability information to the network node. This feedback loop enables the network to make informed configuration decisions that match actual device capabilities, thereby improving both device capability utilization and overall network performance compared to blind worst-case assumptions.
3Reliability
If full-range directional scanning is performed, then signal reception in all directions is ensured, but time consumption and resource usage increase
Solution Approach 1:
The patent applies local quality by adjusting beamforming configuration to match specific device capabilities and requirements. Instead of uniformly performing full-range scanning for all devices, the system tailors the scanning range and beam parameters to each device's actual needs and capabilities, reducing unnecessary time consumption while maintaining adequate signal reception coverage.
Solution Approach 2:
The patent implements partial action by performing beamforming scanning only over the necessary angular range rather than always executing complete full-range scans. By determining appropriate sweeping ranges based on device capabilities and operational context, the system achieves adequate signal reception coverage with reduced time consumption and resource usage.

AI summary
A wireless communication device transmits beam sweeping information that indicates a beam sweeping property of the device, and a network node in an associated wireless communication network configures transmission or reception beamforming with respect to the device at one or more Transmission/Reception in the network, based on the beamforming property. Among the various advantages flowing from configuring network-side beamforming for the device in view of the beamforming property, the network need not configure its beamforming operations according to worst-case or minimum-capability assumptions for the device, and, instead tailors its transmission or reception beamforming in dependence on the beamforming property of the device.
