MAC Uplink Resource Prioritization for Overlapping SR and Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in seamlessly providing services due to conflicts and collisions among multiple resources, leading to inefficient resource usage and degraded performance indicators.
Innovation Solution
A method and user equipment for prioritizing uplink radio resources based on priority values, excluding lower-priority resources from transmission to ensure high-priority resources are used effectively, thereby optimizing resource allocation and reducing inefficiencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple uplink radio resources are allocated simultaneously, then service diversity and data transmission capacity are improved, but resource conflicts and collisions occur leading to degraded performance
Solution Approach 1:
The patent introduces priority values as a new parameter to characterize uplink radio resources. By assigning different priority values to different resources, the system enables differentiated handling of conflicting resources, allowing high-priority resources to be transmitted while low-priority resources are dropped, thus resolving resource conflicts while maintaining overall system productivity
Solution Approach 2:
The patent segments the set of uplink radio resources into different priority levels. By dividing resources into high-priority and low-priority groups, the system can apply different transmission strategies to each segment, ensuring that critical data transmission is maintained while non-critical transmissions are managed during resource conflicts
2Adaptability or versatility
If resource allocation is increased to support more services, then service coverage is improved, but resource conflicts and collisions increase
Solution Approach 1:
The patent adds priority values as a distinguishing parameter for different uplink radio resources. This parameter enables the system to differentiate between resources allocated for different services, allowing the network to identify and resolve conflicts by prioritizing certain services over others when resource collisions occur
Solution Approach 2:
The priority value acts as an intermediary mechanism between resource allocation and conflict resolution. By introducing this intermediate parameter, the system can mediate resource conflicts through prioritization rules, enabling seamless service provision even when multiple services compete for the same resources

AI summary
Provided is an operating method of a user equipment (UE) in a wireless communication system, the operating method including determining, by a medium access control (MAC) entity, a resource corresponding to an uplink radio resource or a scheduling request (SR) transmission resource, identifying, by the MAC entity, at least one uplink radio resource or at least one SR transmission resource other than a deprioritized resource, which overlaps with the resource on a time axis, and identifying, by the MAC entity, a prioritized resource for transmitting at least one of data, control information, or an SR, based on the priority of the at least one uplink radio resource other than the deprioritized resource, the priority of the at least one SR transmission resource other than the deprioritized resource, and a priority of the resource.
