Terminal SRS Transmission Control for Resource Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Rel-15/16 NR standards fail to handle cases of SRS resource overlap, leading to inappropriate SRS transmission and decreased system throughput.
Innovation Solution
A terminal is equipped with a control section that determines whether to transmit or switch SRS resources based on a time difference between SRS resources, ensuring appropriate SRS transmission by controlling the transmission in different SRS resources when the time difference is smaller than a given value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SRS resources are configured with small time difference to increase measurement flexibility, then adaptability is improved, but transmission reliability deteriorates due to resource overlap conflicts
Solution Approach 1:
The patent implements dynamic control of SRS transmission by introducing a time difference threshold mechanism. When the time difference between overlapping SRS resources is below the threshold, the system dynamically adjusts transmission behavior through priority determination and cancellation mechanisms, allowing flexible adaptation while maintaining reliability through controlled conflict resolution
Solution Approach 2:
The patent changes the transmission parameter state by introducing a threshold-based decision mechanism. The control section compares the time difference parameter against a threshold to determine transmission behavior, transforming the static transmission approach into a parameter-driven dynamic system that resolves conflicts based on temporal relationships
2Device complexity
If existing Rel-15/16 NR standards are used without enhancement, then device complexity is reduced, but productivity decreases due to inappropriate SRS transmission
Solution Approach 1:
The patent applies preliminary action by performing conflict detection and resolution before SRS transmission occurs. The control section determines whether to cancel or transmit SRS resources in advance by evaluating time difference thresholds, preventing inappropriate transmission that would reduce system throughput while maintaining manageable complexity through proactive conflict management

AI summary
A terminal according to one aspect of the present disclosure includes: a control section that performs, for transmission of a reference signal for measurement (Sounding Reference Signal (SRS)) of an SRS resource of at least one of a plurality of SRS resources, control of whether to perform transmission or transmission in a different SRS resource, when a time difference between the plurality of SRS resources is smaller than a given value; and a transmitting section that transmits the SRS, based on a result of the control. According to one aspect of the present disclosure, it is possible to appropriately perform SRS transmission.
