Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collisions occur in wireless communication networks, particularly in shared resource pools, leading to inefficiencies and potential data loss or delay in transmissions.
Innovation Solution
User equipment determines resource reselection and activation requests based on the type of collision, whether periodic, series, or one-time, to manage resource conflicts effectively.

Engineering Contradiction Analysis
1Productivity
If multiple user equipment share the same resource pool for transmissions, then resource utilization efficiency is improved, but collision between transmissions occurs leading to data loss or delay
Solution Approach 1:
The patent segments the shared resource pool into different resource types (e.g., periodic resources, series resources, one-time resources) and implements different collision handling strategies for each segment. When a collision is detected, the system identifies the resource type and applies specific reselection logic appropriate to that segment, thereby maintaining high resource utilization while preventing transmission failures.
Solution Approach 2:
The patent implements dynamic resource reselection where the resource allocation strategy changes based on the detected collision type. The system transitions from static resource allocation to dynamic adjustment, where resources are reallocated in real-time based on collision detection results, ensuring both high utilization and reliable transmission.
2Reliability
If resource reselection is performed for every collision, then transmission reliability is improved, but system complexity and overhead increase
Solution Approach 1:
The patent applies different quality levels of collision handling to different resource types. For periodic and series resources, full resource reselection and activation is performed. For one-time resources, simpler reselection without activation is sufficient. This localized approach ensures reliability where needed while reducing complexity for transient collisions.
Solution Approach 2:
The patent changes the handling parameters based on collision type detection. The system monitors collision patterns and adjusts the reselection behavior dynamically - applying aggressive reselection for periodic/series collisions and conservative reselection for one-time collisions, thereby optimizing the balance between reliability and complexity.
3Speed
If resource preemption is allowed for high-priority transmissions, then transmission speed for critical data is improved, but collision frequency increases in shared resource pools
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors resource pool usage and collision patterns. When high-priority preemptions occur, the system detects the resulting collisions and triggers compensatory resource reselection for affected low-priority transmissions. This feedback loop maintains overall resource pool efficiency while allowing necessary preemptions for critical data.
Solution Approach 2:
The patent converts the harmful effect of preemption-induced collisions into a benefit by using collision detection as a trigger for systematic resource reselection. The collisions caused by high-priority transmissions are detected and used to initiate coordinated reselection processes that ultimately improve overall resource utilization and prevent future conflicts.

AI summary
Apparatuses, methods, and systems are disclosed for transmissions based on a type of collision. One method (400) includes determining (402) that a first transmission resource corresponding to a first user equipment preempts a second transmission resource corresponding to a second user equipment as a result of a collision between the first transmission re-source and the second transmission resource in a shared resource pool. The method (400) includes transmitting (404), from the second user equipment, a request for resource reselection and activation in response to a type of collision being a periodic collision or a series collision; or transmitting, from the second user equipment, the request for resource reselection in response to the type of collision being a one-time collision.
