1Productivity

If signal transmission periodicity and transmissions per burst are reduced, then resource utilization is improved, but network performance may be impacted

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic control signaling that allows burst signal parameters (periodicity, transmissions per burst) to be adjusted in real-time based on traffic patterns. This dynamic adaptation enables the system to reduce resource utilization during low-traffic periods while maintaining adequate signal transmission during high-traffic periods, thus resolving the contradiction between resource efficiency and network performance

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes signal parameters (periodicity, transmissions per burst) based on determined traffic patterns to optimize resource usage. By modifying these parameters dynamically rather than using fixed values, the system achieves reduced resource utilization without significantly impacting network performance when traffic conditions permit

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

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

Engineering Contradiction:

Improveresource overheadVSAvoidcontrol complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent uses existing control channels (PDCCH, MAC CE) for their primary control functions while also utilizing them to convey energy saving indications. This multi-functionality allows the system to reduce resource overhead without adding separate dedicated signaling channels, thereby avoiding excessive increase in control complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces energy saving indications as intermediary signals that trigger parameter modifications. These indications act as mediators between traffic pattern determination and actual parameter changes, simplifying the control architecture by using standardized indication mechanisms rather than complex direct control protocols

Inventive Principle:

Principle #24Intermediary (Mediator)

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.
