Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in resource configuration, particularly in network energy saving modes, leading to increased power consumption and signaling overhead due to frequent BWP switching and resource state changes.
Innovation Solution
The method involves configuring periodic resources in a first bandwidth part (BWP) and maintaining an active state in a network energy saving (NES) mode, with specific conditions allowing deactivation of resources, reducing unnecessary power consumption and signaling by minimizing state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BWP switching is performed frequently to adapt to different service requirements, then system adaptability is improved, but power consumption increases and resource usage efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource configuration by introducing a dormant state for BWPs that can be quickly activated or deactivated based on service requirements. This dynamic state management allows the system to adapt to different services without frequent full BWP switches, reducing the energy overhead associated with complete resource reconfiguration while maintaining system adaptability.
Solution Approach 2:
The patent applies local quality by maintaining different states for different BWPs simultaneously - some BWPs can be active while others are dormant. This allows the system to optimize resource usage locally in each BWP based on specific service needs, rather than uniformly switching all resources, thereby reducing overall power consumption while preserving adaptability where required.
2Productivity
If periodic resources are deactivated upon BWP switching to an inactive BWP, then resource usage efficiency is improved, but signaling overhead increases due to frequent activation/deactivation commands
Solution Approach 1:
The patent applies preliminary action by pre-configuring periodic resources in dormant BWPs without immediately deactivating them upon BWP switching. The resources remain in a configured but inactive state, allowing quick reactivation when needed without requiring full reconfiguration signaling. This reduces signaling overhead while maintaining resource usage efficiency through selective activation.
Solution Approach 2:
The patent implements continuity of useful action by maintaining the configuration of periodic resources across BWP transitions in dormant state. Instead of completely deactivating and reactivating resources with each BWP switch, the configuration persists continuously, eliminating the need for repeated activation/deactivation signaling while ensuring resources are available when the BWP becomes active again.
3Loss of information
If periodic resources are maintained active in inactive BWPs to reduce signaling overhead, then signaling efficiency is improved, but power consumption increases
Solution Approach 1:
The patent resolves this contradiction through dynamic state management, introducing a dormant state that allows resource configurations to persist without being fully active. Resources in dormant BWPs are configured and can be quickly activated, but do not consume full power until actually activated. This dynamic approach reduces signaling overhead compared to frequent reconfiguration while avoiding continuous power consumption of fully active resources.
4Productivity
If BWP switching is performed to optimize resource allocation, then resource allocation efficiency is improved, but system complexity increases due to multiple resource state management
Solution Approach 1:
The patent applies segmentation by dividing BWP states into distinct categories: active, dormant, and inactive. This segmentation allows the system to manage resource allocation efficiently by transitioning between well-defined states, reducing the complexity of managing multiple resource states compared to a continuous spectrum of states. Each state has clear activation/deactivation rules, simplifying the overall management logic.

AI summary
A method and apparatus for configuring a resource in a wireless communication system, disclosed in the present specification, comprise the steps of: configuring a periodic resource in a first bandwidth part (BWP); performing BWP switching in which an active BWP is changed from the first BWP to a second BWP; maintaining an active state of the periodic resource on the basis of a network energy saving (NES) mode configured in a UE, even if the BWP switching is performed; and deactivating the periodic resource on the basis of a specific condition being satisfied when the first BWP is a deactivated BWP, wherein, even if the BWP switching is performed, the active state of the periodic resource can be maintained on the basis of the NES mode.
