Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a device reports a high beam switching capability, then resource utilization may be improved, but the configuration may exceed actual device capabilities leading to communication failures
Solution Approach 1:
The patent implements dynamic beam switching configuration where the network can adjust the beam switching configuration based on actual device performance. The configuration is not static but adapts to changing conditions, allowing the system to optimize resource utilization while maintaining reliability by adjusting parameters in real-time based on device feedback and performance metrics.
Solution Approach 2:
The patent employs feedback mechanisms where the device reports its actual beam switching performance and capability to the network. This feedback loop allows the network to adjust the beam switching configuration to match actual device capabilities, preventing over-configuration while maximizing resource utilization. The feedback includes device capability information and performance metrics that guide configuration adjustments.
2Productivity
If the network schedules resources based on a high beam switching configuration, then communication efficiency may be improved, but the device may not be able to perform all scheduled beam switches
Solution Approach 1:
The patent implements a mechanism where the network schedules beam switching configurations that may exceed device capabilities, but the device autonomously determines which beam switches to perform based on its actual capability. This partial action approach allows the system to aim for high communication efficiency while the device selectively executes only those beam switches it can actually perform, maintaining operability.
Solution Approach 2:
The patent changes the parameter of beam switching capability from a fixed reported value to a dynamically adjusted value. The device can adjust its effective beam switching capability based on actual performance, and the network adjusts scheduling parameters accordingly. This parameter change allows the system to optimize for communication efficiency while respecting device operability constraints.
3Reliability
If devices autonomously determine beam switches based on actual capability, then reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts the beam switching decision-making function from the network and places it in the device. Instead of the network controlling every beam switch, the device autonomously determines which beam switches to perform based on its actual capability. This extraction reduces the signaling overhead required for network control while maintaining or improving reliability through device-level intelligence.
Solution Approach 2:
The patent implements self-service where the device autonomously manages its own beam switching operations based on its actual capability. The device monitors its own performance, determines its true beam switching capability, and independently adjusts its beam switching operations without requiring constant network intervention. This self-service approach reduces signaling overhead while maintaining high reliability.

AI summary
The described techniques provide a first device configured to transmit, to a second device, an indication of a beam switching capability. In response, the second device schedules resources for a set of shared channel transmissions based on a first beam switching configuration. If the first beam switching configuration exceeds the beam switching capability of the first device, the first device applies a set of selection rules to the first beam switching configuration to obtain a second beam switching configuration and communicates with the second device according to the second beam switching configuration.
