Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming is extended to multiple TRPs with multiple antennas, then signal transmission quality can be improved, but the complexity of antenna grouping and beamforming configuration increases
Solution Approach 1:
The patent divides the beamforming configuration into separate beam groups, where each beam group corresponds to a specific TRP. This segmentation allows independent configuration and management of beamforming parameters for each TRP, reducing the overall complexity while maintaining the benefits of multi-TRP signal transmission.
Solution Approach 2:
The patent introduces a universal beam group configuration mechanism that can be applied across multiple TRPs. The beam group structure serves multiple functions: identifying TRPs, configuring beam directions, and managing antenna selections. This multi-functional approach simplifies the configuration process compared to handling each TRP independently with separate parameters.
2Productivity
If multiple TRPs with multiple antennas are used for parallel transmission, then data stream transmission capacity increases, but the complexity of performing beamforming measurements and selections increases
Solution Approach 1:
The patent segments the beam measurement process into TRP-specific measurements within each beam group. Instead of performing a single complex measurement across all TRPs and antennas simultaneously, the system measures beam characteristics for each TRP separately, then combines the results. This segmentation reduces the measurement complexity and enables systematic evaluation of multiple data streams.
Solution Approach 2:
The patent implements a feedback mechanism where beam measurement results are used to select optimal beam groups for data transmission. The UE feeds back beam measurement information to the network, which then uses this feedback to determine the best beams for parallel data stream transmission. This feedback loop enables adaptive beam selection that optimizes transmission capacity while managing measurement complexity.
3Reliability
If the number of antennas participating in beamforming is increased, then signal transmission quality improves, but the complexity of configuring and managing beam groups increases
Solution Approach 1:
The patent creates a universal beam group configuration framework that handles multiple antennas and TRPs through a standardized structure. The beam group configuration follows uniform rules and procedures regardless of the number of TRPs or antennas involved. This universality makes the configuration process more manageable and less complex compared to ad-hoc configuration approaches.
Solution Approach 2:
The patent performs preliminary configuration of beam groups before actual data transmission. Beam directions, antenna selections, and TRP associations are pre-configured in beam groups, allowing the system to quickly switch between different beam configurations during operation. This preliminary setup reduces the complexity of real-time configuration adjustments.
