Scheduling Request Resource Selection for Timely Delay Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in existing communication technologies is that user equipment (UE) lacks appropriate scheduling request (SR) resources for timely delay information reporting, leading to delayed or lost buffered data due to the base station's inability to schedule data effectively.
Innovation Solution
A method and apparatus for determining and configuring SR resources based on network-side information to ensure timely reporting of delay information, allowing the UE to send SRs on designated resources for delay information reports, thereby enabling the base station to schedule buffered data efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE uses existing SR resources for non-delay information reports, then the SR resource configuration is simple, but the delay information report cannot be sent timely leading to data loss
Solution Approach 1:
The patent segments SR resources into two distinct types: first SR resources for delay information reports and second SR resources for non-delay information reports. This segmentation allows the UE to selectively use appropriate resources based on the report type, ensuring timely delivery of delay information while maintaining clear resource management and configuration.
Solution Approach 2:
The patent introduces a new dimension of resource allocation by configuring SR resources at the logical channel group (LCG) level rather than just at the UE level. This dimensional change enables more granular control over SR resource usage, allowing specific LCGs to be associated with appropriate SR resources based on whether they carry delay-sensitive information.
2Loss of time
If the UE waits for PUSCH resource allocation for delay information reporting, then resource allocation is efficient, but the reporting is delayed causing buffered data loss
Solution Approach 1:
The patent enables preliminary action by allowing the UE to send SRs for delay information reports immediately on pre-configured first SR resources without waiting for PUSCH allocation. This preliminary SR transmission triggers urgent PUSCH resource allocation, ensuring that delay information reaches the base station within the critical time window while still maintaining efficient resource allocation through subsequent PUSCH assignment.

AI summary
A method for sending the scheduling request (SR) for the delay information report 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, or second configuration information, used to indicate at least one sending resource for an SR for a non-delay information report.
