Wireless Node Resource Allocation for Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G networks, there is a challenge in efficiently scheduling control information transmissions when multiple service priorities are involved, leading to potential decreases in transmission quality and efficiency due to the lack of consideration for control information demands during data channel scheduling.
Innovation Solution
A method where a first signaling determines a radio resource block and bit block size for data, and a second signaling adjusts the number of Resource Elements (REs) occupied by control information, taking into account different priorities and formats to ensure flexible allocation and avoid conflicts between high and low priority transmissions.

Engineering Contradiction Analysis
1Productivity
If a scheduling signaling of a physical-layer data channel is transmitted without considering control information demands, then data transmission efficiency is improved, but control information transmission quality deteriorates
Solution Approach 1:
The patent applies preliminary action by determining the number of resource elements for control information sub-signal before finalizing the data channel scheduling. The method calculates the control information resource requirement based on the second signaling parameters, then adjusts the data channel resource allocation accordingly to ensure both control and data transmissions are properly accommodated.
Solution Approach 2:
The patent implements dynamics by making the resource element allocation for control information adjustable and adaptive. The number of resource elements is dynamically determined based on the second signaling parameters and the timing relationship between first and second signalings, allowing the system to flexibly adapt to different control information demands while maintaining data transmission efficiency.
2Reliability
If multiple service priorities are considered in scheduling, then transmission reliability is improved, but scheduling complexity increases
Solution Approach 1:
The patent applies local quality by differentiating the handling of control information and data based on their respective priorities. The method determines the number of resource elements for control information sub-signal using specific parameters from the second signaling when priority considerations are needed, while using simpler parameters from the first signaling when priority differentiation is not required, thus adding complexity only where necessary.
Solution Approach 2:
The patent implements parameter changes by using different sets of parameters for determining resource element allocation depending on priority requirements. The method switches between using second signaling parameters (when priority consideration is needed) and first signaling parameters (when simple allocation suffices), thereby managing complexity through conditional parameter selection.
3Productivity
If resource elements are dynamically adjusted for control information, then transmission efficiency is improved, but signaling complexity increases
Solution Approach 1:
The patent applies universality by designing the second signaling to serve multiple functions: it not only carries data scheduling information but also provides parameters for determining control information resource element allocation. This multi-functionality allows the system to achieve dynamic resource adjustment without introducing separate dedicated signaling for control information allocation.
Solution Approach 2:
The patent implements merging by combining the control information resource determination function with the existing data channel scheduling signaling. The second signaling that originally served data scheduling now also provides the basis for determining control information resource elements, reducing the need for additional separate signaling mechanisms.
Data Source
AI summary
Method and device in nodes used for wireless communication. A first node receives a first signaling, receives a second signaling, and transmits a first signal in a first radio resource block. The first signal comprises a second sub-signal; a value of a first field in the first signaling is used to indicate a first offset from a first offset set, a value of a first field in the second signaling is used to indicate a second offset from a second offset set, only the second offset is used to determine a number of Resource Element(s) (RE(s)) occupied by the second sub-signal in the first radio resource block; the first signaling is used to determine a first priority, the second signaling is used to determine a second priority, a signaling format of the first signaling is used to determine that the first offset set is related to the first priority.
