SRS Resource Reporting for Dynamic Uplink Channel Sounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for adjusting sounding reference signal (SRS) transmission resources in terminals are inflexible and unable to dynamically respond to changes, leading to ineffective and non-real-time performance.
Innovation Solution
Terminals report expected related information for SRS transmission to network devices, allowing dynamic adjustment of resources such as ports, frequency domains, and time domains, while network devices indicate permission for such reporting to ensure timely and accurate configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminals use existing mechanisms for adjusting SRS transmission resources, then resource configuration can be maintained, but the system lacks flexibility and cannot dynamically respond to changes
Solution Approach 1:
The patent implements dynamic adjustment of SRS transmission resources by allowing terminals to report expected related information (such as expected SRS transmission ports, frequency domain resources, and time domain resources) to the network device. The network device can then dynamically modify resource configuration based on actual channel conditions and network requirements, transforming the static resource allocation into a dynamic adaptive system that responds to changing conditions in real-time.
Solution Approach 2:
The patent establishes a feedback mechanism where terminals report expected SRS transmission information to the network device, which then adjusts resource configuration accordingly. This closed-loop feedback system enables the network device to continuously optimize SRS transmission resources based on terminal reports and network state, improving both adaptability and response time compared to open-loop static configuration.
2Measurement precision
If terminals dynamically report expected SRS transmission information, then resource configuration accuracy and timeliness improve, but system complexity increases
Solution Approach 1:
The patent applies partial action by having terminals report only the expected SRS transmission information that is most critical for resource configuration (such as expected ports, frequency resources, and time resources) rather than complete transmission details. The network device processes only the necessary subset of information to make configuration decisions, reducing processing complexity while maintaining sufficient accuracy for effective resource allocation.
3Productivity
If network devices allow terminal reporting of expected SRS information, then resource allocation timeliness improves, but control overhead increases
Solution Approach 1:
The patent extracts only the essential elements of SRS transmission information that are necessary for resource configuration (expected transmission ports, frequency domain resources, time domain resources) and separates these from other transmission details. By reporting only these extracted key parameters, the terminal reduces control signaling overhead while providing the network device with sufficient information to make timely resource allocation decisions, improving productivity without excessive overhead.
