1Productivity

If wider bandwidth and higher energy consumption are used to achieve higher throughput and larger coverage, then network performance is improved, but energy consumption and signal processing complexity increase making it unsustainable

Engineering Contradiction:
Improvenetwork throughputVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent introduces a reconfigurable intelligent surface (RIS) as an intermediary component between the base station and user equipment. The RIS consists of multiple programmable reflecting elements that can dynamically adjust the phase and amplitude of reflected signals. This intermediary surface enables the network to achieve higher throughput and coverage by intelligently manipulating radio wave propagation, thereby avoiding the need to increase bandwidth and energy consumption at the base station and user equipment.

Engineering Contradiction:
Improvenetwork coverageVSAvoidsignal processing complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The reconfigurable intelligent surface acts as a mediator that extends network coverage by reflecting and redirecting radio signals to areas with poor coverage. The RIS can be deployed in strategic locations to bounce signals around obstacles and into shadowed regions, thereby expanding coverage area without requiring the base station to increase transmission power or bandwidth, thus avoiding increased signal processing complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs dynamic reconfiguration of the intelligent surface's reflecting elements in real-time based on channel conditions and user requirements. The phase and amplitude coefficients of each reflecting element can be dynamically adjusted to optimize signal propagation patterns, enabling the system to adaptively extend coverage areas without increasing overall system complexity through static high-power transmissions.
