Terminal Panel SRS Resource Association for Uplink Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems lack appropriate control and configuration methods for UL transmission when multiple panels are supported, leading to potential deterioration in communication throughput and quality.
Innovation Solution
A terminal equipped with a receiving section for downlink control information and a control section that associates SRS resource sets with panel identifiers, enabling appropriate UL transmission by judging the number of activated SRS resource sets corresponding to the panel identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple panels are supported for UL transmission, then communication capacity and throughput are improved, but control complexity and configuration difficulty increase
Solution Approach 1:
The patent segments the UL transmission configuration by associating different SRS resource sets with different panel identifiers. Each panel is configured with specific SRS resource sets through panel-specific higher layer signaling, allowing independent control and configuration for each panel while maintaining overall system coordination.
Solution Approach 2:
The patent applies local quality by configuring panel-specific parameters for each panel identifier. Different panels can have different SRS resource set associations, spatial relations, and configuration parameters tailored to their specific characteristics and transmission requirements, rather than using a uniform configuration for all panels.
2Reliability
If multiple panels are configured for UL transmission, then communication quality is improved, but configuration management becomes more difficult
Solution Approach 1:
The patent implements feedback mechanisms where the terminal reports panel identifiers and SRS resource set associations to the network. The network uses this feedback information to configure and manage multiple panels appropriately, adjusting configurations based on actual terminal capabilities and operational status.
Solution Approach 2:
The patent applies preliminary action by pre-configuring panel identifiers and SRS resource set associations before actual UL transmission occurs. The terminal capability signaling and higher layer signaling establish the configuration framework in advance, allowing smooth operation during actual communication without real-time configuration complexity.

AI summary
A terminal according to one aspect of the present disclosure includes: a receiving section that receives downlink control information including at least one of information indicating a specific SRS resource set among one or more activated (Sounding Reference Signal (SRS)) resource sets and information related to an active panel identifier or a panel identifier reported by terminal capability signaling; and a control section that judges an association between the specific SRS resource set and the panel identifier, based on the number of activated SRS resource sets corresponding to the panel identifier.
