SRS Antenna Switching Synchronization Across Multiple SRS Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna switching configurations in communication systems fail to synchronously update SRS resources during configuration changes, leading to incomplete power-saving needs and inefficient communication performance.
Innovation Solution
A method for synchronously updating antenna switching configurations for different SRS types, including P-SRS, SP-SRS, and AP-SRS, by selecting and sending SRS resources based on target configurations to ensure consistent use of Tx/Rx antennas or ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate updates are performed for SRS resources of different types during antenna switching configuration, then the system can handle each SRS type independently, but the updates are not synchronized leading to incomplete power-saving and inefficient resource usage
Solution Approach 1:
The patent combines the update operations for SRS resources of different types into a single synchronous update process. When an antenna switching configuration is changed, the system simultaneously updates all SRS resources (first SRS type and second SRS type) to the target configuration, ensuring synchronization and complete power-saving rather than updating them separately
Solution Approach 2:
The patent creates a universal update mechanism that applies to all SRS resource types. The same update logic and configuration changes are applied consistently across different SRS types, ensuring that the antenna switching configuration change is reflected in all SRS resources simultaneously, thereby achieving both synchronization and efficient power-saving
2Adaptability or versatility
If antenna switching configuration is changed for one SRS type, then that specific SRS type can utilize the new configuration, but other SRS types may not reflect the change leading to inconsistent Tx/Rx antenna usage
Solution Approach 1:
The patent implements a universal antenna switching configuration update mechanism that affects all SRS resource types simultaneously. The same configuration changes are applied to both first and second SRS types, ensuring that the Tx/Rx antenna assignments remain consistent across all SRS resources and maintaining system stability while achieving adaptability
3Ease of manufacture
If SRS resources are not synchronously updated, then the system can simplify the update process, but it leads to incomplete power-saving and inefficient terminal resource usage
Solution Approach 1:
The patent merges multiple separate update operations into a single synchronous update process. By combining the updates for different SRS types into one operation, the system maintains relative simplicity while achieving complete power-saving, as all SRS resources are updated together rather than requiring multiple separate update cycles

AI summary
A method for sending sounding reference signal (SRS) used for antenna switching configuration is performed by a terminal. The method includes: determining an SRS type configured by the terminal for antenna switching configuration, wherein the SRS type includes at least two different SRS types; determining that an antenna switching configuration corresponding to an SRS resource of a first SRS type is changed to a target antenna switching configuration, and synchronously updating an antenna switching configuration corresponding to an SRS resource of a second SRS type as the target antenna switching configuration; selecting an SRS resource corresponding to the target antenna switching configuration as a target SRS resource; and sending the SRS resource of the first SRS type and the SRS resource of the second SRS type based on an antenna or an antenna port corresponding to the target SRS resource.
