Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SRS time-domain resource selection methods do not adequately consider differences in interference levels on different symbols due to factors like atmospheric waveguides, leading to suboptimal allocation and degraded uplink and downlink system performance.
Innovation Solution
A method for dynamically selecting SRS time-domain resources by evaluating performance parameters, including interference influence factors, to identify and replace suboptimal configurations with those offering improved system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SRS is allocated on U subframes to increase the number of SRS time-domain symbols, then SRS capability and period are improved, but the number of available symbols for uplink service channels is reduced, resulting in increased uplink code rate and decreased throughput
Solution Approach 1:
The patent implements dynamic selection of SRS time-domain resource configuration, allowing the system to adaptively choose between different SRS allocation schemes (S subframe or U subframe) based on real-time channel conditions and interference levels, rather than using a fixed allocation pattern
Solution Approach 2:
The system dynamically changes the time-domain resource configuration parameters of SRS, including the selection of specific symbols and subframes, based on measured interference levels and channel conditions to optimize the balance between SRS capability and uplink throughput
2Productivity
If SRS is allocated on S subframes to avoid uplink service channel resource reduction, then uplink throughput is maintained, but interference from atmospheric waveguide and remote cells is significantly higher, degrading SRS-based channel estimation accuracy
Solution Approach 1:
The system measures interference levels on different SRS symbols and uses this feedback information to dynamically select the optimal SRS time-domain resource configuration, switching between S subframe and U subframe allocations based on measured conditions
Solution Approach 2:
The system dynamically changes the time-domain resource configuration parameters of SRS, including the selection of specific symbols and subframes, based on measured interference levels and channel conditions to optimize the balance between throughput and estimation accuracy
3Device complexity
If a fixed SRS time-domain resource configuration is used, then system complexity is reduced, but the system cannot adapt to varying interference conditions, leading to degraded performance in atmospheric waveguide scenarios
Solution Approach 1:
The patent transforms the static SRS resource configuration into a dynamic system that can adapt to varying interference conditions, implementing a selection mechanism between different pre-configured SRS time-domain resource patterns based on measured channel conditions
Solution Approach 2:
The system pre-configures multiple SRS time-domain resource configurations and prepares selection criteria in advance, allowing rapid adaptation to changing conditions without complex real-time optimization calculations
