1Use of energy by moving object

If signal transmission periodicity and transmissions per burst are reduced to save energy, then power consumption decreases, but network performance may be impacted

Engineering Contradiction:

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements dynamic adjustment of signal transmission parameters (periodicity and transmissions per burst) based on real-time traffic conditions. The base station monitors traffic patterns and dynamically modifies synchronization signal and reference signal transmission characteristics, transitioning from static to adaptive operation to optimize the trade-off between energy consumption and network performance.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes physical transmission parameters (signal periodicity and number of transmissions per burst) to achieve energy savings. By reducing the periodicity interval and decreasing transmissions per burst during low-traffic conditions, the system modifies operational parameters to lower power consumption while maintaining acceptable performance levels.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If dynamic control signaling is used to modify burst signal parameters, then resource utilization improves, but control signaling overhead increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies partial control signaling by only modifying burst signal parameters when traffic conditions warrant changes. Instead of continuously adjusting parameters, the system selectively applies control signaling during periods when resource optimization is beneficial, reducing unnecessary overhead while maintaining improved resource utilization during appropriate time windows.

Inventive Principle:

AI summary

Downlink signals, such as synchronization signals and/or reference signals, may be used for facilitating communications between communication devices. The downlink signals may be dynamically reconfigured, for reduced resource consumption, using control channel signaling with reduced resource overhead. Reconfiguration of downlink signals may be based on determined traffic volume in the communication network to minimize any impact of the reconfiguration on network performance.
