Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-beam transmission is used for power-saving signal, then transmission simplicity is maintained, but multi-beam coverage capability is lost
Solution Approach 1:
The patent divides the power-saving signal transmission into multiple beams across different time units. Each beam corresponds to a specific time unit, allowing the network to transmit power-saving signals to terminal devices in RRC idle state through multiple beams simultaneously, achieving multi-beam coverage while maintaining manageable complexity through systematic segmentation of transmission opportunities.
2Reliability
If terminal monitors power-saving signal continuously, then power-saving signal reception reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic monitoring of power-saving signals at specific time units rather than continuous monitoring. The terminal device monitors power-saving signals only at predetermined time units configured by the network, which maintains reliable reception of power-saving information while significantly reducing power consumption compared to continuous monitoring.
3Area of stationary object
If power-saving signal is transmitted on all time units, then signal coverage is maximized, but transmission resource waste increases
Solution Approach 1:
The patent applies local quality by transmitting power-saving signals only on specific time units corresponding to actual beam directions needed for coverage. Instead of transmitting on all time units uniformly, the system selectively transmits on predetermined time units based on beam configuration, optimizing energy utilization while maintaining necessary coverage in relevant directions.
