Separate Power Control Adjustment States for SRS and PUSCH
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack the ability to configure separate power control adjustment states for sounding reference signal (SRS) transmissions and physical uplink shared channel (PUSCH) transmissions, leading to inefficiencies in power management and interference management between SRS and PUSCH resources.
Innovation Solution
Implementing a method where a user equipment (UE) and base station can configure separate power control adjustment states for SRS transmissions and PUSCH transmissions, allowing for distinct power control settings indicated by a first or second SRS power control adjustment state, which are managed through uplink power control configurations and DCI formats like DCI 2_3, enabling independent power control for SRS and PUSCH.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate power control adjustment states are configured for SRS and PUSCH transmissions, then power control accuracy and interference management are improved, but device complexity and configuration overhead increase
Solution Approach 1:
The patent segments the power control adjustment states into separate configurations for SRS transmissions and PUSCH transmissions. By introducing distinct power control adjustment state indicators for SRS resources, the system divides the previously unified power control mechanism into independent controllable units, enabling separate optimization of power control accuracy for each transmission type while managing complexity through structured segmentation.
Solution Approach 2:
The patent adds a new dimension to power control configuration by introducing separate power control adjustment state indicators specifically for SRS transmissions. This dimensional expansion allows the system to independently control power parameters along the SRS transmission dimension without affecting PUSCH power control, thereby improving overall power control accuracy while maintaining manageable configuration complexity through organized parameter separation.
2Object-affected harmful factors
If separate power control adjustment states are configured for SRS and PUSCH transmissions, then interference management between SRS and PUSCH is improved, but uplink power control configuration overhead increases
Solution Approach 1:
The patent segments interference management into separate power control adjustment mechanisms for SRS and PUSCH transmissions. By configuring independent power control adjustment state indicators for SRS resources, the system creates separate control pathways that enable targeted interference management between SRS and PUSCH transmissions, reducing mutual interference while organizing configuration overhead through structured parameter separation.
Solution Approach 2:
The patent applies local quality by configuring power control adjustment states specifically tailored for SRS transmissions rather than using a unified approach. This localized power control configuration allows the system to optimize interference management for SRS-specific conditions and requirements, applying appropriate power control parameters locally to SRS resources while maintaining separate PUSCH power control, thereby improving interference management efficiency.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an uplink power control configuration for a sounding reference signal (SRS) resource set associated with an uplink component carrier, wherein the uplink power control configuration configures separate power control adjustment states between SRS transmissions and physical uplink shared channel (PUSCH) transmissions, and wherein the uplink power control configuration indicates one of a first SRS power control adjustment state or a second SRS power control adjustment state. The UE may transmit, to the base station, an SRS based at least in part on the uplink power control configuration for the SRS resource set. Numerous other aspects are described.
