Sidelink Resource Configuration for Out-of-Coverage Collision Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sidelink communication systems face challenges in efficiently configuring resources for vehicle-to-everything (V2X) communications, particularly in managing collisions and latency issues, especially for out-of-coverage terminals.
Innovation Solution
The implementation of a software-configurable air interface manager that dynamically configures parameters such as waveform, frame structure, multiple access scheme, and coding/modulation to optimize sidelink communications, allowing for flexible resource allocation and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If preconfigured uplink resources are allocated for sidelink communications, then resource allocation efficiency is improved, but interference to other communications increases
Solution Approach 1:
The patent implements dynamic resource allocation where the network entity can adjust or release preconfigured uplink resources based on current network conditions and traffic demands. This allows the system to transition from static preconfiguration to adaptive resource management, optimizing the balance between allocation efficiency and interference mitigation.
Solution Approach 2:
The patent modifies resource allocation parameters by introducing mechanisms to release or modify preconfigured resources. The network entity can change resource allocation states from preconfigured to dynamically allocated based on conditions, thereby adjusting system behavior to reduce interference while maintaining efficiency.
2Object-affected harmful factors
If dynamic resource allocation is implemented, then interference is reduced, but resource allocation complexity increases
Solution Approach 1:
The patent segments resource allocation into two distinct modes: preconfigured resources for low-complexity scenarios and dynamically allocated resources for interference-sensitive scenarios. This segmentation allows the system to select appropriate allocation methods based on conditions, reducing overall complexity while managing interference.
Solution Approach 2:
The network entity acts as an intermediary that manages the transition between preconfigured and dynamic resource allocation. It receives conditions from user equipment and decides whether to maintain, release, or modify resource configurations, thereby simplifying the complexity burden on individual devices.
3Quantity of substance
If preconfigured resources are maintained without release mechanisms, then resource availability is improved, but resource waste increases
Solution Approach 1:
The patent implements a resource release mechanism where preconfigured uplink resources can be discarded (released) when no longer needed or when conditions change. The network entity can send release indications to user equipment, allowing resources to be recovered and reallocated to other uses, thereby eliminating waste while maintaining availability when needed.
Solution Approach 2:
The patent introduces periodic evaluation of resource allocation conditions where the network entity assesses whether preconfigured resources should be maintained or released based on current traffic patterns and network state. This periodic review prevents permanent resource allocation and enables adaptive resource management.

AI summary
A sidelink (SL) configuration for SL communications directly between a communication terminal and another communication terminal is separate from a communication network link configuration for communications with network equipment in some embodiments. An SL configuration, which could be an SL reconfiguration or an SL preconfiguration for use by the communication terminal after the terminal transitions from in coverage to out of coverage, could be transmitted through network/terminal signaling, and detailed examples of such signaling are disclosed herein. An SL configuration could be or include an SL bandwidth part (BWP) configuration and an SL communication resource configuration, such as one or more resource pools, within the SL BWP. An SL configuration that is determined and transmitted by network equipment to one or more terminals could also or instead involve a common or initial SL configuration to be used for SL communications by multiple communication terminals.
