SRS Resource Set Configuration for Shared Uplink Reference Validity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current mobile communications systems, network devices cannot determine whether a same SRS resource can be configured in multiple SRS resource sets, affecting the validity of mobile communication.
Innovation Solution
The network device sends configuration information to the terminal device to determine if a target SRS resource can be configured in multiple SRS resource sets, considering factors such as SRS usage, time domain characteristics, and downlink beam reports to ensure valid resource configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network device configures multiple SRS resource sets for the terminal device, then the beam management capability is improved, but the network device cannot determine whether a same SRS resource can be configured in the plurality of SRS resource sets, affecting validity of mobile communication
Solution Approach 1:
The patent introduces a new parameter 'usage' with different values (beam management, codebook-based transmission, non-codebook-based transmission, antenna switching) to differentiate SRS resource set configurations. By changing the parameter values, the system enables the network device to determine whether the same SRS resource can be configured in multiple SRS resource sets, thus resolving the reliability issue while maintaining adaptability
Solution Approach 2:
The patent introduces configuration information as an intermediary that carries the usage parameter from the network device to the terminal device. This intermediary enables the transmission of determination criteria, allowing the terminal device to correctly interpret whether the same SRS resource can be shared across multiple SRS resource sets, thereby resolving the communication validity problem
2Productivity
If the network device configures the same SRS resource in multiple SRS resource sets, then the resource utilization efficiency is improved, but the complexity of determining resource configuration validity increases
Solution Approach 1:
The patent uses the 'usage' parameter to simplify the determination process. Instead of complex validation logic, the network device simply checks whether the usage parameter values match. This parameter-based approach enables efficient resource utilization while keeping the determination complexity low
Solution Approach 2:
The patent applies different usage parameter values to different SRS resource sets based on their specific purposes. By assigning appropriate usage values locally to each resource set, the system enables precise control over resource sharing decisions, improving resource utilization without requiring global complex validation
