Solution Overview
Problem
Existing 5G mobile communication systems face challenges in managing uplink and downlink transmissions on overlapping frequency-domain resources, leading to mutual interference and inefficient resource utilization.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink and downlink transmissions are performed on overlapping frequency-domain resources, then resource utilization is improved, but mutual interference occurs and transmission reliability deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where the network can flexibly configure and adjust uplink and downlink frequency-domain resources based on real-time traffic conditions and channel states. This dynamic adjustment allows the system to optimize resource utilization while preventing interference by adapting resource assignments to current system needs, resolving the contradiction between high resource utilization and transmission reliability.
Solution Approach 2:
The patent changes the parameter of frequency-domain resource allocation from static to configurable, allowing the network to adjust the frequency ranges, bandwidths, and resource block assignments for uplink and downlink transmissions. By modifying these parameters dynamically, the system can avoid overlapping resources when interference would occur while maintaining high utilization when resources can be efficiently shared, thus resolving the reliability-utilization contradiction.
2Reliability
If frequency-domain resources are allocated separately for uplink and downlink, then transmission reliability is maintained, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent makes frequency-domain resources universal by allowing the same frequency resources to be used for both uplink and downlink transmissions under controlled conditions. Through configurable resource allocation, the system can assign frequency resources that serve multiple purposes - acting as uplink resources when needed and downlink resources when needed, or being shared between directions with appropriate interference management. This multi-functionality increases resource utilization efficiency while maintaining reliability through proper configuration.
Solution Approach 2:
The patent applies preliminary action by pre-configuring frequency-domain resource allocation patterns and interference avoidance rules before actual transmissions occur. The network pre-establishes resource allocation schemes that anticipate potential interference scenarios, allowing the system to maintain high resource utilization while ensuring transmission reliability is preserved through pre-planned resource separation or sharing strategies.
3Productivity
If flexible resource allocation is implemented, then resource utilization is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the network monitors the actual performance and interference levels of configured frequency-domain resources, then adjusts resource allocations based on this feedback. The system receives feedback on transmission quality, resource utilization effectiveness, and interference conditions, and uses this information to dynamically optimize resource configuration. This feedback loop allows the system to achieve high resource utilization while managing complexity through data-driven decision-making rather than overly complex predetermined schemes.
Data Source
AI summary
A terminal and a method performed by the terminal are disclosed. The method includes receiving, from a base station, configuration information on frequency domain resources; identifying a symbol corresponding to both an uplink RB and a downlink RB based on the configuration information; and in case that an SS/PBCH block comprising synchronization signals and a physical broadcast channel is in the symbol, skipping a transmission of an uplink channel on the uplink RB of the symbol.
