Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The R17 unified transmission configuration indicator framework does not provide a method for determining beam information and power control parameter information of the Sounding Reference Signal (SRS), which is essential for establishing consistent beam links and ensuring accurate data transmission in wireless communications systems.
Innovation Solution
A parameter determining method and apparatus that determine configuration information of the SRS within the unified transmission configuration indicator framework, including beam information and power control parameter information, using various methods such as common configuration information, MAC CE indications, and protocols like R15 and R16, to ensure consistent understanding between network devices and terminal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the R17 unified TCI framework is implemented, then common beam information can be indicated to terminal devices through downlink signaling, but the method for determining beam information and power control parameter information of SRS is not provided
Solution Approach 1:
The patent applies universality by enabling the unified TCI framework to serve multiple purposes: it provides common beam information for downlink channels while also determining beam information and power control parameters for uplink SRS through the same framework, making the system more versatile without adding separate mechanisms
Solution Approach 2:
The patent uses downlink signaling as an intermediary to convey SRS configuration information. The network device indicates TCI states through downlink signaling, which terminal devices then use to determine both downlink beam information and uplink SRS parameters, effectively using the downlink channel as a mediator to solve the information loss problem
2Manufacturing precision
If separate configuration methods are used for different channels, then specific beam information can be controlled, but system complexity increases
Solution Approach 1:
The patent merges the configuration of beam information and power control parameters for SRS with the existing unified TCI framework. Instead of creating separate configuration mechanisms, it combines these functions into the existing downlink signaling system, reducing overall system complexity while maintaining precise control
Solution Approach 2:
The unified TCI framework is designed to serve multiple functions simultaneously: it provides beam information for downlink channels, determines uplink SRS beam information, and controls power parameters, thereby reducing the need for separate configuration systems and lowering overall complexity

AI summary
A parameter determining method includes determining configuration information of an SRS in a unified transmission configuration indicator framework, where the configuration information of the SRS includes at least one of beam information of the SRS or power control parameter information of the SRS.
