UE-Initiated Beam Reporting Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing resources for user equipment (UE)-initiated reporting, particularly in 5G/NR communication systems where high data rates and robust coverage are required.
Innovation Solution
The implementation of a UE that includes a transceiver configured to receive information for transmitting a beam report, and a processor to determine PUCCH and PUSCH resources, enabling efficient UE-initiated reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE-initiated reporting is implemented for beam reports, then reporting efficiency and reliability are improved, but resource management complexity increases
Solution Approach 1:
The patent segments the reporting process into two distinct parts: a compact indicator transmitted via PUCCH (physical uplink control channel) for efficient resource utilization, and the complete beam report details transmitted via PUSCH (physical uplink shared channel) when needed. This segmentation allows the system to handle UE-initiated reporting with minimal resource overhead by first establishing intent through the indicator, then transferring detailed information only when necessary.
2Productivity
If PUCCH and PUSCH resources are dynamically determined, then resource allocation efficiency is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the UE with multiple PUCCH resources and establishing the framework for dynamic PUSCH resource allocation before actual reporting occurs. The UE processor is pre-programmed with the logic to determine appropriate PUCCH resources based on indicator type and PUSCH resources based on report content, enabling rapid resource selection during actual reporting without requiring complex real-time calculations.

AI summary
Methods and apparatuses for resource management for user equipment (UE)-initiated reporting. A method performed by a UE includes receiving first information related to a physical uplink control channel (PUCCH) for transmission of an indicator to indicate transmission of a beam report, receiving second information related to a physical uplink shared channel (PUSCH) for transmission of the beam report, and determining a PUCCH resource based on the first information. The method further includes determining, based on the indicator or the determined PUCCH resource and the second information, a PUSCH resource, transmitting the indicator via the PUCCH resource, and transmitting the beam report via the PUSCH resource.
