User Equipment Sidelink Resource Allocation by Range and Periodicity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently allocating resources for sidelink communications, particularly in scenarios where different types of communications have varying range and periodicity requirements, leading to suboptimal performance and interference issues.
Innovation Solution
A method and apparatus for user equipment (UE) to dynamically allocate resources based on the range and periodicity thresholds of different communication types, such as BRID and DAA, by semi-statically or dynamically configuring resource pools with specific QoS, transmit power, and interference coordination criteria, enabling efficient sidelink communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resources are allocated without considering different communication types, then resource allocation is simple, but interference increases and service quality deteriorates
Solution Approach 1:
The patent segments the resource allocation process by separating different communication types (first type with long-range/high-priority requirements and second type with short-range/low-priority requirements) into distinct resource pools. This allows each communication type to receive appropriate resources without interference, improving service quality while maintaining manageable complexity through structured classification.
Solution Approach 2:
The patent applies local quality by assigning different resource allocation characteristics to different communication types. The first communication type receives resources configured for long-range transmission with higher priority, while the second type receives resources optimized for short-range transmission. This localized optimization ensures each communication type receives tailored service quality matching its specific requirements.
2Object-affected harmful factors
If uniform resource allocation is used for all communications, then system complexity is reduced, but interference between different communication types increases
Solution Approach 1:
The patent divides the resource pool into separate allocations for different communication types, preventing interference by ensuring first type communications and second type communications use distinct resources. This segmentation approach reduces harmful interference while the complexity is managed through clear typological classification and standardized allocation rules for each type.
Solution Approach 2:
The patent introduces communication type classification as an intermediary mechanism that mediates between resource allocation and communication requirements. By categorizing communications into types with different characteristics, the system can allocate resources appropriately without direct complex interactions between all possible communication scenarios, reducing interference while maintaining manageable system complexity.
3Productivity
If dynamic resource allocation based on communication type is implemented, then resource allocation efficiency improves, but allocation delay increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring resource pools for different communication types before actual resource allocation is needed. The system prepares and maintains separate resource pools tailored for first type and second type communications, so when allocation is required, resources can be assigned quickly from pre-prepared pools rather than allocating from scratch, improving efficiency while minimizing delay.
Solution Approach 2:
The patent implements dynamics by enabling the system to adaptively select and allocate resources based on the detected communication type. The resource allocation mechanism dynamically adjusts its behavior according to whether first type or second type communication is detected, allowing efficient resource distribution while the dynamic nature of the system responds quickly to changing conditions without significant delay.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain information associated with a first type of communication and a second type of communication, the first type of communication having a range requirement that satisfies a range requirement threshold and a periodicity that satisfies a periodicity threshold and the second type of communication having a range requirement that does not satisfy the range requirement threshold and a periodicity that does not satisfy the periodicity threshold. The UE may allocate one or more resources for a sidelink communication to be transmitted by the UE based at least in part on the information. Numerous other aspects are described.
