Uplink Reporting Conflict Resolution via Priority Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in efficiently processing beam reporting, CSI reporting, and beam failure recovery requests due to resource conflicts in uplink channel resources, leading to potential interruptions and reduced reliability in beam links.
Innovation Solution
A method for determining resource conflicts between different types of reporting information and prioritizing their transmission, where the user side device transmits reporting information with the highest priority level first and may drop or delay lower-priority information, using joint encoding or multiplexing to maximize uplink channel resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If beam reporting, CSI reporting, and beam failure recovery requests are transmitted simultaneously, then information completeness is improved, but resource conflict occurs leading to transmission reliability degradation
Solution Approach 1:
The patent segments the transmission process by dividing reporting information into different priority levels (first priority and second priority). This segmentation allows the system to handle multiple reporting types (beam reporting, CSI reporting, beam failure recovery requests) separately based on their urgency, ensuring that critical information is transmitted reliably while less critical information can be deferred or dropped during resource conflicts.
Solution Approach 2:
The patent implements preliminary action by determining priority levels for different reporting information types before actual transmission occurs. The network device pre-configures priority relationships among various reporting types, and the terminal device pre-identifies which reports have higher or lower priority. This preliminary prioritization enables rapid conflict resolution when resource conflicts arise, without requiring complex real-time arbitration.
2Loss of information
If all reporting information is transmitted without prioritization, then information completeness is improved, but resource utilization efficiency deteriorates due to conflicts
Solution Approach 1:
The patent applies local quality by assigning different transmission qualities (priorities) to different types of reporting information based on their specific characteristics. Beam failure recovery requests are assigned high priority because they affect link reliability, while CSI reporting may be assigned lower priority as it is more tolerant of delays. This localized quality differentiation optimizes resource utilization by allocating more resources to critical transmissions and fewer resources to less critical ones.
Solution Approach 2:
The patent changes the parameter of transmission priority dynamically based on the type of reporting information. By adjusting the priority parameter (from first priority to second priority), the system can adapt resource allocation to match the actual needs of different reporting types, thereby improving overall resource utilization efficiency while ensuring that no critical information is lost.
3Reliability
If high-priority reporting information is transmitted first, then transmission reliability of critical information is improved, but information completeness may be compromised due to dropping lower-priority reports
Solution Approach 1:
The patent extracts and separates high-priority reporting information from low-priority reporting information during the transmission process. When a resource conflict is detected, the system extracts only the necessary high-priority information for immediate transmission and sets aside or drops the low-priority information. This extraction approach ensures that critical information (such as beam failure recovery requests) is transmitted reliably without being blocked by less important reports.

AI summary
The present disclosure provides a reporting information transmission method, a user side device and a network side device. The reporting information transmission method includes: determining whether there is a resource conflict between uplink channel resources for carrying at least two pieces of reporting information, the at least two pieces of reporting information at least including two of a beam failure recovery request, SS block-based beam reporting, CSI-RS-based beam reporting, and CSI reporting; and when there is the resource conflict between the uplink channel resources, transmitting one or more of the at least two pieces of reporting information.
