Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in handling explosively increasing data traffic, high per-user transmission rates, and supporting a large number of devices with very low end-to-end latency and high-energy efficiency, particularly in the context of multi-panel user equipment (UE) operations.
Innovation Solution
A method for transmitting an uplink channel in a wireless communication system that involves transmitting UE capability information related to multiple panels, receiving scheduling information, and determining the transmission of the uplink channel based on panel-level correspondence and collision handling rules, allowing for simultaneous transmission of multiple channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple uplink channels are transmitted simultaneously through multiple panels, then the data transmission rate and system capacity are improved, but the complexity of scheduling and collision management increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting panel activation states, transmission power levels, and resource allocation parameters based on channel conditions and traffic demands. The base station modifies scheduling parameters such as panel-specific resource grants, power control commands, and collision resolution parameters to optimize multi-panel transmission while managing system complexity.
Solution Approach 2:
The patent implements dynamics by enabling flexible, real-time activation and deactivation of panels based on current transmission needs. The system dynamically adjusts which panels are active, their transmission configurations, and resource allocations according to varying channel conditions, traffic patterns, and interference levels, allowing the system to adapt its complexity to actual operational requirements.
2Reliability
If detailed UE capability information and panel-level correspondence information are transmitted, then the reliability of uplink channel transmission is improved, but the signaling overhead increases
Solution Approach 1:
The patent applies segmentation by dividing UE capability information into hierarchical levels: general UE capabilities, panel-specific capabilities, and panel-level correspondence information. This segmented approach allows the system to transmit only the necessary level of detail for each operational context, reducing overall signaling overhead while maintaining reliability where needed.
Solution Approach 2:
The patent implements local quality by providing detailed panel-level correspondence information only for specific panels or frequency regions where it is needed for reliable operation, rather than uniformly across all panels. The base station selectively requests and processes detailed capability information based on current scheduling requirements, reducing unnecessary signaling overhead.
3Productivity
If panel-specific scheduling information is transmitted for each frequency region, then the efficiency of resource utilization is improved, but the signaling overhead increases
Solution Approach 1:
The patent applies universality by establishing panel-level correspondence that allows a single panel configuration or capability indication to serve multiple frequency regions simultaneously. When panels are designated as corresponding across frequency regions, the same scheduling information can be applied universally across multiple regions, reducing the need for separate panel-specific signaling for each frequency region.
Solution Approach 2:
The patent implements merging by combining panel-level correspondence information across frequency regions, allowing the system to treat corresponding panels in a unified manner. This merging enables the base station to issue consolidated scheduling commands that apply to multiple frequency regions simultaneously, reducing redundant signaling overhead while maintaining efficient resource utilization.
