Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink switching is performed frequently between multiple bands to improve spectrum utilization, then throughput and spectrum utilization are improved, but the time interval between switching operations becomes insufficient leading to transmission inefficiency
Solution Approach 1:
The patent applies preliminary action by performing uplink switching operations in advance according to a pre-configured switching pattern before the minimum time interval expires. The UE is configured with a switching pattern that includes switching points and time intervals, allowing the UE to proactively switch uplink bands at predetermined moments rather than waiting for buffer thresholds to be reached, thus maintaining continuous transmission while respecting minimum interval constraints.
2Reliability
If uplink switching is performed with sufficient time interval to ensure stable transmission, then transmission reliability is improved, but spectrum utilization and throughput are reduced
Solution Approach 1:
The patent applies dynamics by making the uplink switching pattern configurable and adaptable. The network can dynamically adjust the switching pattern parameters (time intervals, switching points) based on channel conditions, buffer states, and QoS requirements. This allows the system to optimize between reliability and productivity by adjusting the switching frequency and timing according to real-time conditions, rather than using fixed switching intervals.
3Adaptability or versatility
If multiple uplink bands are configured to enable flexible switching, then adaptability and spectrum utilization are improved, but device complexity increases
Solution Approach 1:
The patent applies feedback by implementing a switching pattern configuration mechanism where the network provides feedback to the UE about the configured switching pattern, and the UE reports its capability and status back to the network. The network can adjust the switching pattern based on UE feedback regarding buffer states, channel conditions, and switching capability. This feedback loop simplifies the complexity by allowing centralized management of the switching logic while enabling the UE to operate autonomously according to the configured pattern.
