Multi-Panel Uplink Scheduling for Overlap Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks do not effectively address time-domain overlaps in simultaneous uplink transmissions by multi-panel UEs, leading to communication failures and inefficiencies in multi-TRP scenarios.
Innovation Solution
A method for a user equipment (UE) to resolve time-domain overlaps in uplink transmissions by selecting antenna panels and managing simultaneous transmissions using multiplexing or dropping based on scheduling configurations, signaling, and predetermined rules to ensure no more than one transmission occurs at a given time via a same component carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous multi-panel uplink transmissions are performed, then throughput and network performance are improved, but time-domain overlaps cause communication failures and reliability deteriorates
Solution Approach 1:
The patent segments the uplink transmission resources by associating different transmissions with different antenna panels. When time-domain overlaps are detected, the UE resolves conflicts on a per-panel basis, allowing simultaneous transmissions on different panels while preventing conflicts within the same panel. This segmentation enables maintaining high throughput through parallel transmissions while ensuring reliability by preventing overlapping transmissions within each panel.
Solution Approach 2:
The patent implements dynamic transmission management where the UE continuously monitors for time-domain overlaps and adaptively adjusts transmissions based on detected conflicts. The system dynamically selects which transmissions to perform or drop based on real-time overlap detection, enabling flexible resource utilization that maximizes throughput while preventing communication failures from simultaneous transmissions on the same panel.
2Adaptability or versatility
If multiple transmissions are scheduled on the same antenna panel, then resource utilization is improved, but time-domain overlaps cause transmission conflicts and productivity decreases
Solution Approach 1:
The patent employs dynamic conflict resolution mechanisms that monitor scheduled transmissions and adaptively manage resource allocation. When time-domain overlaps are detected on the same antenna panel, the system dynamically determines which transmissions to perform and which to drop, optimizing resource utilization while preventing transmission conflicts that would reduce productivity.
Solution Approach 2:
The patent implements feedback-based transmission management where the UE detects time-domain overlaps and uses this information to make informed decisions about which transmissions to perform. The system continuously monitors transmission schedules and adjusts resource utilization based on detected conflicts, ensuring high transmission efficiency while maintaining flexible resource allocation.
3Reliability
If per-panel transmission resolution is implemented, then communication reliability is improved, but device complexity increases due to additional panel management
Solution Approach 1:
The patent segments the transmission management function by antenna panel, with each panel independently resolved for time-domain overlaps. This segmentation approach improves reliability by ensuring no conflicts occur within each panel while keeping the complexity manageable through modular per-panel processing rather than complex global coordination.
Solution Approach 2:
The patent implements self-service transmission resolution where the UE autonomously detects time-domain overlaps and resolves conflicts without requiring complex network coordination. The device independently manages its own panel assignments and transmission decisions, improving reliability through consistent panel-specific resolution while avoiding the complexity of external coordination mechanisms.

AI summary
The disclosure relates to a method to be performed by a user equipment (UE). The method includes: receiving a scheduling configuration that configures the UE to perform a plurality of transmissions on a plurality of uplink (UL) resources; selecting, based on a mapping of the plurality of UL resources to antenna panels, a plurality of antenna panels for the plurality of transmissions; and, on a per-panel basis, resolving a time-domain overlap for at least two of the plurality of transmissions such that no more than one transmission is transmitted by each panel at a given time via a same component carrier (CC). The disclosure also relates to another method as well as a UE.
