Sidelink Dynamic Resource Allocation for Hybrid Traffic Demand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems waste semi-static sidelink resources when there is no traffic, leading to inefficiencies and resource wastage.
Innovation Solution
Implementing a hybrid resource allocation system that combines semi-static and dynamic resource regions, allowing UEs to dynamically request additional resources in the dynamic region when needed, thereby optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If semi-static sidelink resources are allocated for each link, then communication reliability is improved, but resource wastage increases when there is no traffic
Solution Approach 1:
The patent applies dynamics by transitioning from static resource allocation to dynamic resource allocation. The system maintains semi-static resources for reliable communication while introducing dynamic resource selection mechanisms that allow UEs to adapt resource usage based on actual traffic conditions, eliminating wastage during idle periods while preserving reliability during active communication.
Solution Approach 2:
The patent segments resource allocation into two distinct types: semi-static resources that provide reliability guarantees and dynamic resources that optimize for current traffic conditions. This segmentation allows the system to maintain reserved resources for critical communications while freeing up resources during low-traffic periods, resolving the contradiction between reliability and resource wastage.
2Stability of the object's composition
If semi-static resources are allocated per link, then communication stability is improved, but signaling overhead increases
Solution Approach 1:
The patent implements partial action by allocating semi-static resources only for the minimum necessary stable communication requirements, rather than full resource allocation. Dynamic resource selection supplements this partial allocation only when needed, reducing overall signaling overhead while maintaining communication stability through the semi-static portion.
Solution Approach 2:
The patent makes resources universal by creating a shared dynamic resource pool that multiple UEs can access based on current needs, rather than dedicating exclusive resources to each link. This multi-functionality allows the same resources to serve multiple purposes and multiple UEs, reducing total signaling requirements while maintaining stability through the semi-static allocation.
3Adaptability or versatility
If dynamic resource selection is implemented, then resource allocation flexibility is improved, but system complexity increases
Solution Approach 1:
The patent segments the resource allocation system into semi-static and dynamic components, where the complex dynamic selection operates only on the flexible portion of resources. This segmentation isolates the complexity to manageable portions while maintaining overall flexibility, as the semi-static portion handles stable requirements and the dynamic portion handles adaptive needs.
Solution Approach 2:
The patent implements self-service through autonomous UE-based dynamic resource selection, where UEs independently select resources from the dynamic pool based on their own traffic conditions without requiring complex centralized control. This distributes the complexity from the network to individual devices, improving flexibility while managing system complexity through decentralized decision-making.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select one or more additional resources in a dynamic resource region for a second set of communications to a second UE, the one or more additional resources being in addition to one or more resources in a semi-static resource region for a first set of communications to the second UE. The UE may transmit, to the second UE, a request that the one or more additional resources be reserved for the second set of communications to the second UE. Numerous other aspects are described.
