Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face challenges in effectively transmitting uplink control information and data, particularly in scenarios requiring low latency and high reliability, such as IoT applications, due to limitations in resource allocation and beamforming techniques.
Innovation Solution
The method involves a UE and base station collaboration using advanced resource allocation strategies and beamforming techniques, including the use of multiple panels for transmission and reception, to optimize uplink control information and data transmission, allowing for efficient transmission even in scenarios with overlapping PUCCH and PUSCH resources across different TRPs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional single-panel transmission is used, then device complexity is reduced, but transmission reliability and efficiency deteriorate in overlapping PUCCH and PUSCH resource scenarios
Solution Approach 1:
The patent divides the transmission system into multiple panels (first panel and second panel), each capable of independent transmission. The UE can selectively activate specific panels for PUCCH or PUSCH transmission based on resource overlap conditions, enabling segmented transmission that improves reliability without requiring all panels to be always active.
Solution Approach 2:
The patent implements dynamic panel selection where the UE determines which panel(s) to activate based on real-time transmission conditions. When PUCCH and PUSCH resources overlap, the UE dynamically switches between single-panel and multi-panel transmission modes, adjusting the transmission configuration adaptively rather than using a fixed panel setup.
2Productivity
If single TRP transmission is used, then resource allocation is simple, but transmission efficiency deteriorates in multi-TRP overlapping resource scenarios
Solution Approach 1:
The patent merges transmission operations across multiple TRPs by allowing the UE to transmit PUCCH and PUSCH simultaneously using different panels when resources overlap. This combining approach enables the system to utilize multiple TRPs' resources efficiently, improving overall transmission productivity while managing complexity through coordinated control.
Solution Approach 2:
The patent creates a universal transmission framework where panels can serve multiple functions - they can be used for PUCCH transmission, PUSCH transmission, or both simultaneously depending on the scenario. This multi-functionality allows the same physical infrastructure to handle various transmission efficiency requirements without dedicated separate systems.
3Adaptability or versatility
If beamforming is optimized for single scenario, then beamforming performance is good for that scenario, but adaptability to different TRP and panel configurations deteriorates
Solution Approach 1:
The patent changes beamforming parameters dynamically based on the active panel configuration and TRP scenario. When multiple panels are activated for overlapping resource transmission, the system adjusts beamforming parameters to optimize signal directionality and interference management for each specific panel-TRP combination, enabling adaptability across different configurations.
