Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple benchmarks and performance metrics are reported separately for beam prediction, then measurement precision is improved, but overhead and latency increase
Solution Approach 1:
The patent combines multiple benchmark beam reports and performance metrics into a single unified beam report structure. Instead of transmitting separate reports for each benchmark and metric, the invention merges them into one consolidated report that contains all necessary information about predicted beams, benchmark beams, and associated performance metrics, thereby reducing overall reporting overhead while maintaining complete measurement precision
Solution Approach 2:
The unified beam report structure serves multiple functions simultaneously: it reports predicted beam information, benchmark beam information, and performance metrics all in one transmission. This multi-functional approach eliminates the need for separate reporting mechanisms for each type of information, reducing latency and overhead while maintaining comprehensive monitoring capability
2Measurement precision
If multiple benchmarks and performance metrics are reported separately for beam prediction, then measurement precision is improved, but latency increases
Solution Approach 1:
By merging multiple separate reports (predicted beam report, benchmark beam report, and performance metric reports) into a single unified beam report, the invention reduces the number of transmission events required. This consolidation decreases the total time needed for complete performance monitoring feedback, thereby reducing latency while maintaining all measurement precision requirements
Solution Approach 2:
The patent prepares and structures all beam prediction information, benchmark information, and performance metrics in advance within a unified report framework before transmission. This preliminary organization of all required data in a single structure enables more efficient one-time transmission, reducing the cumulative latency that would result from multiple sequential report transmissions
3Quantity of substance
If joint encoding of benchmark beams is implemented, then overhead is reduced, but device complexity increases
Solution Approach 1:
The joint encoding process merges the encoding of predicted beams, benchmark beams, and performance metrics into a single encoding operation. By combining these elements into one unified encoding process rather than separate encoding steps, the invention reduces overall processing overhead and simplifies the encoding architecture, thereby reducing device complexity while achieving overhead reduction

AI summary
Embodiments of the invention relate to beam evaluation for communication devices (100, 300) in a communication system (500). A first communication device (100) jointly encodes a set of benchmark beams for a set of predicted beams to obtain a jointly encoded beam report. The set of benchmark beams are determined based on measured reference signals received from a second communication device (300) in a set of transmit beams of the second communication device (300). The first communication device (100) reports the jointly encoded beam report in a beam report (510) to the second communication device (300). The jointly encoded beam report enables the second communication device (300) to perform beam evaluation in an efficient way with minimal overhead. Furthermore, the invention also relates to corresponding methods and a computer program.
