WTRU Uplink Resource Prioritization for Overlap Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless transmit/receive units (WTRUs) face challenges in efficiently handling overlapping uplink resources due to insufficient processing time, leading to conflicts and inefficiencies in data transmission.
Innovation Solution
The WTRU determines processing times for overlapping uplink resources and designates one as a prioritized resource based on thresholds, generates a single or multiple transport blocks and control information, and performs preemption procedures to manage conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the WTRU transmits on multiple overlapping uplink resources, then the data transmission capacity is improved, but the processing time requirement increases and conflicts occur
Solution Approach 1:
The patent segments the uplink transmission by dividing overlapping resources into prioritized and non-prioritized categories. The WTRU identifies a first uplink resource as prioritized and a second uplink resource as non-prioritized when they overlap in time, then transmits only on the prioritized resource. This segmentation resolves the contradiction by selecting one resource for transmission rather than attempting to use both simultaneously, thereby maintaining processing time requirements while ensuring reliable data transmission.
2Reliability
If the WTRU designates a prioritized uplink resource from overlapping resources, then transmission conflicts are reduced, but the resource utilization efficiency decreases
Solution Approach 1:
The patent applies preliminary action by establishing clear prioritization criteria before transmission occurs. The WTRU is configured to determine which uplink resource has higher priority based on pre-defined rules (such as resource type, QoS requirements, or network configuration) before the actual transmission decision is made. This preliminary designation of prioritized resources eliminates conflicts during transmission while maintaining efficient resource utilization, as the WTRU can confidently transmit on the prioritized resource without needing to evaluate multiple overlapping options in real-time.
3Reliability
If the WTRU performs preemption procedures on overlapping transmissions, then transmission conflicts are resolved, but the system complexity increases
Solution Approach 1:
The patent applies inversion by reversing the traditional approach to conflict resolution. Instead of implementing complex preemption procedures where one transmission actively interrupts or cancels another, the WTRU inverts the logic by selecting only the prioritized uplink resource for transmission and simply not transmitting on the non-prioritized overlapping resource. This inverted approach resolves transmission conflicts effectively while minimizing system complexity, as it eliminates the need for active preemption mechanisms and focuses on straightforward resource selection based on pre-established priorities.

AI summary
Systems, methods, and devices for transferring data with different reliabilities. A wireless transmit/receive unit (WTRU) is configured with a first modulation and coding set (MCS) table and a second MCS table. The WTRU monitors for a radio network temporary identifier (RNTI). If the WTRU detects a first value for the RNTI, data is transferred with a first reliability. If the WTRU detects a second value for the RNTI, data is transferred with a second reliability.
