Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink and downlink channels are transmitted in overlapping time-frequency resources, then resource utilization efficiency is improved, but interference between channels increases
Solution Approach 1:
The patent segments the uplink and downlink channels into different frequency resources within the same slot for XDD operation, or into different time resources for TDD operation. This segmentation allows overlapping transmission while reducing interference by ensuring proper resource separation when needed.
Solution Approach 2:
The patent transitions from traditional single-dimension resource allocation to multi-dimensional resource management by configuring uplink and downlink resources across both frequency and time dimensions simultaneously, enabling flexible overlapping transmission patterns that optimize both utilization and interference management.
2Duration of action of stationary object
If XDD system configures uplink and downlink in different frequency resources of same slot, then service continuity is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic resource configuration where the system can adaptively switch between XDD mode (different frequency resources in same slot) and TDD mode (different time resources) based on service requirements. This dynamic approach maintains service continuity while managing complexity through flexible, condition-based operation.
Solution Approach 2:
The patent changes the resource allocation parameters dynamically, switching between frequency-domain separation (XDD) and time-domain separation (TDD) configurations. This parameter change allows the system to maintain service continuity for extended periods while adapting to different operational conditions.
3Productivity
If overlapping uplink channels are transmitted, then data rate is improved, but interference management difficulty increases
Solution Approach 1:
The patent incorporates feedback mechanisms where the base station receives uplink channels and provides processing feedback to the terminal. This feedback loop enables continuous optimization of interference management while maintaining high data rates through overlapping transmissions, as the system can adjust based on received signal quality and interference levels.
Data Source
AI summary
Methods and apparatuses in a wireless communication system are provided. Capability information regarding the terminal is transmitted. The capability information is associated with an X division duplexing (XDD) system. Resource configuration information is received based on the resource configuration information. A resource on which uplink control information (UCI) is to be transmitted is determined. The UCI is transmitted on the determined resource. The XDD system configures an uplink resource and a downlink resource in a same slot in different frequency resources.
