PUCCH Resource Selection for SR, HARQ, and UEI Beam Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing overlapping resources for Physical Uplink Control Channel (PUCCH) transmissions, particularly for Scheduling Request (SR), UE-Initiated beam reporting, and Hybrid Automatic Repeat Request (HARQ) in next-generation networks like 5G, leading to potential misalignment in network understanding of multiplexed content.
Innovation Solution
A method for User Equipment (UE) to determine and manage overlaps among PUCCH resources for SR, UEI beam reporting, and HARQ, and transmit HARQ and information to a network node, ensuring proper resource allocation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple PUCCH resources are allocated for SR, UEI beam reporting, and HARQ transmissions, then the coverage of control information is improved, but resource overlap and misalignment between network and UE occur
Solution Approach 1:
The patent introduces a feedback mechanism where the UE transmits indication information about the selected PUCCH resource code-point to the network node. This feedback loop ensures that the network is informed of the UE's resource selection, enabling proper alignment and avoiding misalignment issues in subsequent communications.
Solution Approach 2:
The patent uses indication information as an intermediary element that carries details about the selected PUCCH resource. This intermediary mechanism bridges the UE and network node, ensuring that both sides have consistent understanding of which resource was selected, thereby resolving the misalignment problem.
2Loss of energy
If PUCCH resources are multiplexed to reduce overhead, then spectrum efficiency is improved, but network understanding of multiplexed content becomes misaligned
Solution Approach 1:
The UE provides feedback to the network node about which PUCCH resource code-point was selected from the multiplexed set. This feedback ensures that despite resource multiplexing, the network maintains accurate understanding of the intended transmission, preventing misalignment while preserving spectrum efficiency.
3Adaptability or versatility
If UE autonomously selects PUCCH resources without network coordination, then transmission flexibility is improved, but resource conflicts and misalignment increase
Solution Approach 1:
The patent introduces indication information as an intermediary that conveys the UE's autonomous resource selection to the network. This allows the UE to maintain transmission flexibility by autonomously selecting resources, while the intermediary ensures the network is informed, preventing alignment losses.

AI summary
Methods, systems, and apparatuses are provided for transmitting reports in a wireless communication system, wherein a method for a User Equipment (UE) comprises determining an overlap among a first set of Physical Uplink Control Channel (PUCCH) resources for Scheduling Request (SR), a second set of PUCCH resources for an indication associated with UE-Initiated (UEI) beam reporting and a third PUCCH resource for a Hybrid Automatic Repeat Request (HARQ), and transmitting the HARQ and information to a network node, wherein the information indicates one code-point among the first set of PUCCH resources for SR and the second set of PUCCH resources for the indication.
