V2X Resource Allocation for Secondary Link Channel State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resource allocation methods for Vehicle-to-Everything (V2X) services, specifically in NR V2X mode 1, fail to accurately allocate resources for multiple secondary links maintained by a single transmitting UE, leading to inadequate or excessive resource allocation, resulting in delayed data transmission or resource waste.
Innovation Solution
A resource allocation method where the transmitting UE acquires and reports secondary link information, including channel state information associated with a destination identifier, allowing the base station to allocate resources more accurately based on data transmission requirements for each secondary link, thereby distinguishing and managing multiple secondary links effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station allocates resources for multiple secondary links maintained by the same transmitting UE, then data transmission can be enabled on multiple links, but the allocated resources do not meet data transmission requirements (either too few causing delay or excessive causing waste)
Solution Approach 1:
The patent segments the resource allocation process by introducing separate resource allocation auxiliary information for each secondary link. Instead of allocating resources as a single block, the system divides the allocation into link-specific segments, where each segment includes channel state information and resource requirements tailored to individual secondary links. This segmentation enables precise resource distribution that matches the actual needs of each link.
Solution Approach 2:
The patent implements a feedback mechanism where the transmitting UE reports channel state information and resource allocation auxiliary information to the base station for each secondary link. This feedback loop allows the base station to continuously monitor the actual channel conditions and adjust resource allocation accordingly, ensuring that resources are allocated accurately based on real-time requirements rather than static assumptions.
2Device complexity
If the base station allocates resources without link-specific information, then the allocation process is simple, but the allocated resources do not match actual channel state requirements
Solution Approach 1:
The patent applies preliminary action by having the transmitting UE prepare and report resource allocation auxiliary information before the base station makes final resource allocation decisions. The UE pre-gathers channel state information and calculates required resources for each secondary link, then transmits this information to the base station. This preliminary preparation enables the base station to make informed allocation decisions without requiring complex real-time calculations.

AI summary
Disclosed are a resource allocation method and apparatus for a V2X service, and a storage medium, a terminal and a base station. The method comprises: for an auxiliary link having a requirement for resource allocation, acquiring resource allocation auxiliary information of the auxiliary link; and sending auxiliary link information, wherein the auxiliary link information comprises the resource allocation auxiliary information, and the resource allocation auxiliary information is associated with a destination identifier of the auxiliary link. By means of the solution provided in the present invention, content included in auxiliary link information reported by a UE in a mode 1 can be optimized, such that a resource allocated by a base station to an auxiliary link is better fitted to the actual channel state of the auxiliary link, thereby preventing causing confusion between a plurality of auxiliary links.
