Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication protocols are supported across diverse wireless devices and base stations, then the network's compatibility and coverage are improved, but the system complexity and difficulty of managing communication protocols increase
Solution Approach 1:
The patent segments the communication protocol support by introducing a protocol indication field that divides the protocol stack into identifiable layers (RRC, PDCP, RLC, MAC, PHY). Each layer can be independently configured and managed, allowing the network to handle multiple protocols without overwhelming system complexity. The segmentation enables selective activation of protocol features based on device capabilities and network conditions.
Solution Approach 2:
The patent implements dynamic protocol configuration where the network can adjust protocol parameters, bandwidth parts, and carrier aggregation settings in real-time based on traffic load, device capabilities, and channel conditions. This dynamic adaptation allows the system to maintain compatibility across diverse devices while managing complexity through flexible, condition-based protocol selection rather than static universal support.
2Productivity
If protocol configuration is optimized for specific wireless device capabilities, then communication efficiency is improved, but the difficulty of detecting and measuring device-specific parameters increases
Solution Approach 1:
The patent employs preliminary action by implementing capability indication mechanisms where devices pre-report their supported protocols, bandwidth part preferences, and carrier aggregation capabilities before actual data transmission. The network uses this advance information to pre-configure optimal protocol stacks and parameters, eliminating the need for complex real-time detection and measurement during communication establishment.
Solution Approach 2:
The patent implements feedback loops where devices report channel quality indicators, buffer status, and protocol performance metrics back to the network. The network uses this feedback to continuously optimize protocol configuration for each device, achieving high communication efficiency through adaptive tuning rather than complex initial detection of all device parameters.
3Productivity
If bandwidth parts and carrier aggregation are dynamically adjusted, then resource allocation efficiency is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent applies local quality by configuring different bandwidth parts and protocol parameters for different frequency resources and device locations. Instead of uniformly complex processing across all resources, the network assigns simplified protocol stacks to devices with basic capabilities while providing enhanced protocol features only to devices that require and can handle them. This localized optimization improves resource allocation efficiency without universally increasing device complexity.
Data Source
AI summary
A wireless device receives one or more radio resource control (RRC) messages. The RRC messages indicate a cell group comprises a first cell and a second cell and transmission based on a demodulation reference signal (DM-RS) bundle is enabled for the first cell. The wireless device further receives a downlink control information (DCI) scheduling, for the first cell, transmission of one or more repetitions of an uplink signal within the DM-RS bundle. The wireless device transmits the one or more repetitions within the DM-RS bundle. The wireless device skips monitoring, during a time duration corresponding to the DM-RS bundle, downlink signals via the first cell of the cell group and the second cell of the cell group.
