Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems, particularly in future radio communication systems like NR, face challenges in configuring CORESET and BWP effectively, leading to potential deterioration in communication throughput and frequency use efficiency when controlling based on Bandwidth Parts.
Innovation Solution
A user terminal with a control section that determines the relationship between a control resource set and a BandWidth Part, enabling transmission and/or reception based on detected downlink control information within the specified CORESET and BWP, allowing for appropriate configuration and management of CORESET and BWP parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control is performed based on BWP configuration, then frequency use efficiency is improved, but communication throughput may deteriorate
Solution Approach 1:
The patent applies dynamics by making the control resource set configuration adaptable and changeable based on BWP status. The network device can dynamically adjust whether a control resource set is associated with a deactivated BWP, allowing the system to transition between different control configurations depending on whether bandwidth parts are active or deactivated, thus resolving the contradiction between frequency efficiency and throughput
Solution Approach 2:
The patent changes the parameter of control resource set association by introducing a configurable parameter that determines whether control resource sets can be associated with deactivated BWPs. By adjusting this parameter, the system can optimize for either frequency efficiency (when associated) or throughput (when not associated), depending on operational requirements
2Adaptability or versatility
If multiple BWPs are configured for UE, then flexible control is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing the control resource set configuration to serve multiple functions: it can be associated with both active and deactivated BWPs, and the same configuration mechanism handles both cases. This multi-functional approach allows flexible control across different BWP states without requiring separate complex configuration systems for each state
Solution Approach 2:
The patent applies preliminary action by pre-configuring control resource sets that can be associated with deactivated BWPs before activation occurs. This allows the system to have control resources ready in advance, reducing the complexity of dynamic reconfiguration when BWPs are activated or deactivated

AI summary
A user terminal according to one aspect of the present invention includes: a control section that decides a relationship between a certain control resource set and a certain BandWidth Part (BWP); and a transmission/reception section that, when detecting downlink control information in the certain control resource set, performs transmission and/or reception in the certain BWP based on the relationship. According to the one aspect of the present invention, it is possible to prevent a communication throughput from lowering even when performing control based on a BWP.
