Reference Signal Omission or Delay for SRS Resource Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms to handle resource conflicts in reference signal transmissions, leading to resource waste and miscommunication between base stations and user equipment due to prioritization rules that limit the availability of sounding reference signal (SRS) resources.
Innovation Solution
A mechanism for determining whether to omit or postpone conflicting reference signal transmissions by considering transmission properties and resource overlap, allowing dynamic decision-making based on factors like length, ratio, location, and purpose of SRS resources.

Engineering Contradiction Analysis
1Device complexity
If fixed prioritization rules are used to handle reference signal transmission conflicts, then the decision-making process is simple, but resource utilization is inefficient and communication consistency deteriorates
Solution Approach 1:
The patent implements dynamic decision-making by evaluating multiple transmission properties (length, ratio, location, purpose) of reference signal transmissions rather than using fixed prioritization rules. The base station and UE dynamically determine whether to omit or postpone conflicting transmissions based on real-time assessment of these properties, enabling efficient resource utilization while maintaining communication consistency.
2Reliability
If reference signal transmissions are postponed to ensure resource availability, then transmission conflicts are resolved, but time loss increases and productivity decreases
Solution Approach 1:
The patent segments the reference signal transmission collection into individual transmissions that can be independently evaluated. By assessing each transmission's properties (length, ratio, location, purpose) separately, the system can selectively omit only the conflicting transmissions while maintaining others, rather than postponing the entire collection. This segmentation approach resolves conflicts without causing unnecessary time loss.
3Reliability
If all conflicting reference signal transmissions are omitted, then resource conflicts are avoided, but measurement precision and communication reliability deteriorate
Solution Approach 1:
The patent applies local quality by differentiating between individual transmissions within the collection based on their specific properties. Instead of uniformly omitting all conflicting transmissions, the system evaluates each transmission's length, ratio, location, and purpose to determine the most appropriate action. This localized approach maintains measurement precision by preserving essential transmissions while avoiding conflicts in others.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a collection of reference signal transmissions. The UE may identify a resource overlap between the collection of reference signal transmissions and another resource that is unavailable for reference signal transmissions. The UE may identify one or more transmission properties for the collection of reference signal transmissions. The UE may determine, based at least in part on the one or more transmission properties and the resource overlap, whether to omit one or more of the reference signal transmissions of the collection of reference signal transmissions in the corresponding resource overlap or to delay transmission of the collection of reference signal transmissions. The UE may transmit at least a portion of the collection of reference signal transmissions based at least in part on the determining.
