Scheduling Request Resource Selection for Delay Information Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User Equipment (UE) faces challenges in determining suitable SR resources for delay information reports, leading to delayed or lost buffered data due to the base station's inability to obtain timely reports, which affects scheduling efficiency.
Innovation Solution
A method where the UE determines a target sending resource for an SR based on SR resource information configured by the network side device, using either first configuration information for dedicated SR resources or second configuration information for shared resources, ensuring timely transmission of delay information reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UE uses existing SR resources configured for non-delay information reports, then the device complexity is reduced and ease of operation is improved, but the reliability deteriorates because the base station cannot obtain delay information reports in a timely manner, leading to data loss
Solution Approach 1:
The patent segments SR resources into two distinct types: first configuration information for delay information report SR resources and second configuration information for non-delay information report SR resources. This segmentation allows the UE to select appropriate resources based on the report type, ensuring timely transmission for delay-sensitive reports while maintaining operational simplicity through configured resource pools.
Solution Approach 2:
The patent applies local quality by assigning specific SR resources tailored to the characteristics of delay information reports. Instead of using a uniform SR resource allocation, the network configures dedicated resources (first configuration information) with appropriate timing and frequency characteristics suited for time-critical delay reports, while separate resources (second configuration information) handle non-time-critical reports.
2Reliability
If the network configures dedicated SR resources for delay information reports, then the reliability of timely report transmission is improved, but the device complexity and resource overhead increase
Solution Approach 1:
The patent implements universality by designing a unified SR resource configuration framework that handles both delay information reports and non-delay information reports. The network configures multiple SR resource pools with different characteristics, and the UE selects the appropriate pool based on the report type, allowing the system to serve multiple purposes through a single configuration mechanism.
Solution Approach 2:
The patent utilizes parameter changes by configuring SR resources with different parameters optimized for specific report types. First configuration information includes parameters suited for time-critical reports (e.g., shorter periodicity, specific frequency locations), while second configuration information contains parameters for non-time-critical reports. The UE adjusts resource selection based on these parameter differences without requiring complex decision logic.
3Loss of substance
If the UE waits for PUSCH resources to be allocated before sending delay information reports, then the loss of substance is reduced by ensuring proper scheduling, but the loss of time increases causing timeout and data loss
Solution Approach 1:
The patent applies preliminary action by pre-configuring SR resources specifically for delay information reports before the UE needs to send such reports. When a delay report needs to be sent, the UE can immediately use the pre-configured first configuration information resources without waiting for dynamic PUSCH allocation, ensuring timely transmission while the network prepares appropriate scheduling based on the received SR.
Solution Approach 2:
The patent enables skipping by allowing the UE to bypass the normal scheduling request and allocation process for delay information reports. Instead of waiting for the standard UL grant allocation sequence, the UE directly transmits the delay report using pre-configured SR resources, rushing through the scheduling process to meet tight timing requirements, and allowing the network to catch up with appropriate PUSCH allocation afterward.

AI summary
This application discloses a method and an apparatus for sending a scheduling request SR for a delay information report, and relates to the field of communications technologies. The method for sending the scheduling request SR for the delay information report in embodiments of this application includes: A terminal determines, in a case that the terminal determines that a delay information report is triggered, a target sending resource for an SR based on SR resource information configured by a network side device, where the SR is triggered by reporting the delay information report. The terminal sends the SR to the network side device on the target sending resource, where the SR resource information includes at least one of the following: first configuration information, used to indicate at least one sending resource for the SR; and second configuration information, used to indicate at least one sending resource for an SR for a non-delay information report.
