Uplink Transmission Control for Overlapping Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G radio communication systems, managing overlapping uplink (UL) transmissions with different priorities and cancellation information is challenging, particularly in controlling UL transmission based on cancellation information when multiple signals overlap.
Innovation Solution
A terminal and base station that receive downlink control information related to resource cancellations, allowing for the application of first UL transmission control based on priority and second UL transmission control based on cancellation information when multiple UL transmissions overlap, ensuring appropriate UL transmission even with cancellation operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UL transmission control based on priority is applied, then communication efficiency is improved, but control complexity increases when multiple UL transmissions overlap
Solution Approach 1:
The patent segments the UL transmission control into two distinct control mechanisms: priority-based control and cancellation information-based control. This segmentation allows the system to handle different types of UL transmissions differently, improving overall communication efficiency while managing control complexity through structured classification of control scenarios
Solution Approach 2:
The patent applies preliminary action by pre-configuring priorities for different UL transmissions and pre-establishing cancellation rules before actual transmissions occur. This preliminary configuration enables the terminal to automatically resolve overlapping transmissions without real-time complex decision-making, thus improving efficiency while keeping control complexity manageable
2Reliability
If cancellation operation is applied to UL transmission, then delay reduction and reliability are improved, but transmission control becomes uncertain when overlapping transmissions exist
Solution Approach 1:
The patent implements feedback mechanisms where the terminal reports its UL transmission status and receives updated cancellation information from the base station. This feedback loop ensures that cancellation operations are coordinated with the actual transmission state, improving reliability while maintaining control certainty through continuous status synchronization
Solution Approach 2:
The patent changes the parameter of transmission control by introducing a hierarchical control structure where priority levels and cancellation flags modify the basic transmission behavior. This parameter-based control allows flexible adjustment of transmission characteristics while maintaining deterministic control through well-defined parameter relationships
3Adaptability or versatility
If multiple UL transmissions with different priorities are scheduled, then service diversity is improved, but resource management complexity increases
Solution Approach 1:
The patent applies local quality by assigning different priority levels and control characteristics to different UL transmissions based on their specific service requirements. This allows each transmission to be optimized for its particular service type while the overall system manages complexity through localized rather than global control decisions
Solution Approach 2:
The patent introduces dynamics by allowing the priority and cancellation status of UL transmissions to be dynamically adjusted based on current network conditions and service requirements. This dynamic control enables the system to adapt to diverse services while managing complexity through standardized dynamic adjustment mechanisms rather than static complex configurations

AI summary
A terminal according to an aspect of the present disclosure includes a receiving section that receives downlink control information including information related to a resource for which an UL transmission is canceled, and a control section that performs control to first apply one of first UL transmission control and second UL transmission control and then apply the other when a plurality of UL transmissions that overlap in a time domain are scheduled or configured and at least one of the plurality of UL transmissions uses the resource for which the UL transmission is canceled, the first UL transmission control being based on a priority of each UL transmission, the second UL transmission control being based on information related to the resource for which the UL transmission is canceled.
