Engineering Contradiction Analysis
1Productivity
If SRS transmission power is controlled using multiple parameters (first parameter, second parameter, and third parameter), then communication efficiency and flexibility are improved, but device complexity and control complexity increase
Solution Approach 1:
The patent implements dynamic SRS transmission power control by allowing the system to adaptively select between different parameter sets (first and second parameters, or first, second, and third parameters) based on current communication conditions. This enables the control mechanism to be flexible and responsive to changing channel conditions while maintaining manageable complexity through structured parameter selection
Solution Approach 2:
The patent changes the parameters used for SRS power control dynamically - using different combinations of parameters (first parameter alone, first and second parameters, or all three parameters) depending on the specific communication scenario. This parameter variability allows the system to optimize communication efficiency for different conditions without requiring a permanently complex control structure
2Measurement precision
If SRS transmission power is determined based on multiple parameters, then transmission power control precision is improved, but signaling overhead and processing requirements increase
Solution Approach 1:
The patent applies partial parameter sets for SRS power control - using only the necessary subset of parameters (first parameter, or first and second parameters, or all three) based on the specific communication needs. This avoids the overhead of always transmitting and processing all possible parameters, while still achieving sufficient precision when required
Solution Approach 2:
The first parameter serves multiple functions - it can be used alone for basic power control or in combination with second and third parameters for enhanced control precision. This multi-functionality reduces overall signaling overhead by eliminating the need for separate mechanisms for different control scenarios

AI summary
A user equipment (UE) is described. The UE includes reception circuitry configured to receive information of a first parameter, a second parameter, and a third parameter for a sounding reference signal (SRS) bandwidth in an uplink bandwidth part (UL BWP). The UE also includes transmission circuitry configured to transmit the SRS. In a case that the first parameter and the second parameter are received, a transmission power of the SRS is determined based on the first parameter and the second parameter. In a case that the first parameter, the second parameter, and the third parameter are received, the transmission power of the SRS is determined based on the first parameter, the second parameter, and the third parameter.
