Base Station Resource Information Energy Saving Mode Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Base stations in mobile communication systems face challenges in determining whether received resource information from neighboring stations indicates a usage status under energy-saving mode, leading to potential overloading and inefficient load balancing.
Innovation Solution
Incorporating identification information in resource information to distinguish between usage statuses under energy-saving and normal conditions, allowing base stations to accurately assess load and manage handovers and energy-saving mode applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If energy saving mode is applied to reduce power consumption by stopping radio resources, then power consumption is reduced, but the base station cannot accurately determine resource usage status leading to potential overloading
Solution Approach 1:
The patent introduces an intermediary indicator (energy saving mode indicator) that is transmitted along with resource usage status information. This indicator acts as a mediator that clarifies whether the reported resource usage status is under normal operation or energy saving mode, enabling the receiving base station to accurately interpret the status without requiring additional complex communication overhead.
2Device complexity
If resource information is transmitted without identification of energy saving mode status, then communication overhead is reduced, but the receiving base station cannot appropriately determine handover decisions
Solution Approach 1:
The patent segments the resource status information transmission by separating it into two parts: the resource usage status information and an energy saving mode indicator. This segmentation allows the receiving base station to quickly determine whether the reported status reflects full resource availability or reduced availability due to energy saving mode, enabling accurate handover decisions without requiring complex additional communication protocols.

AI summary
A base station according to an embodiment comprises: a receiver configured to receive resource information indicating a usage status of radio resources of a node to which an energy saving mode in which consumed power is reduced by stopping a use of at least a part of radio resources is applied. The resource information includes identification information for identifying whether or not the usage status indicated by the resource information is a usage status of radio resources available when the energy saving mode is applied.
