Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems with Non-Terrestrial Networks (NTN), the challenge lies in accurately indicating frequency domain resources and beams for uplink and downlink transmissions, as existing methods fail to ensure that control and data information use the same beam, leading to potential reception or transmission issues.
Innovation Solution
The solution involves generating and transmitting downlink control signaling that includes both frequency domain indication and beam indication information, ensuring that the indicated frequency domain resource corresponds to the same beam, thereby aligning the resources and beams for proper communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate beam indication and frequency domain resource indication are used in downlink control signaling, then flexibility in resource allocation is improved, but reliability of transmission is worsened because control and data information may use different beams
Solution Approach 1:
The patent combines beam indication information and frequency domain resource indication information into a unified downlink control signaling structure. By merging these previously separate indications, the system ensures that control information and data information use the same beam, thereby maintaining reliability while preserving allocation flexibility.
Solution Approach 2:
The patent implements feedback mechanisms where the network device receives uplink feedback information from user equipment and uses this feedback to adjust and optimize the unified beam and resource indication. This feedback loop ensures that the system adapts to channel conditions while maintaining consistent beam usage for control and data transmissions.
2Adaptability or versatility
If beam and frequency domain resource indication are separated in uplink control and data information, then resource management flexibility is improved, but communication reliability is worsened due to potential beam mismatch
Solution Approach 1:
The patent merges uplink beam indication and uplink frequency domain resource indication into a unified signaling approach. This ensures that uplink control information and uplink data information are transmitted using the same beam, eliminating beam mismatch issues while maintaining flexible resource management capabilities.
Solution Approach 2:
The system employs feedback mechanisms where user equipment sends uplink feedback that helps the network device optimize the unified beam and resource allocation. This feedback ensures reliable uplink communication while preserving resource management flexibility through adaptive adjustments.
3Measurement precision
If multiple beams are used for different frequency domain resources, then resource allocation precision is improved, but system complexity is worsened due to increased indication overhead
Solution Approach 1:
The patent combines beam indication and frequency domain resource indication into a single unified signaling mechanism. This merging reduces the overall indication overhead and simplifies the system architecture while maintaining precise resource allocation, as the unified indication inherently links specific beams with specific frequency domain resources.
