Multicast Data Reception in V2V Communication Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Vehicle-to-Vehicle (V2V) communication systems, existing technologies face challenges in efficiently managing multicast data transmission, leading to increased load on receiving communication apparatuses due to the need to receive information from distant sources, which can result in inefficient resource allocation and processing burdens.
Innovation Solution
A communication apparatus and base station system that utilizes a receiver to receive predetermined multicast data based on a corresponding relationship between identification information and geographical area information, allowing for targeted data transmission and reception, with a controller managing message requests and resource allocation to optimize data transfer across geographical zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multicast data is transmitted from distant communication apparatuses across geographical areas, then data coverage is improved, but receiving apparatuses experience increased processing load and resource consumption
Solution Approach 1:
The system segments the multicast data transmission by introducing area identification information that divides the coverage into distinct geographical zones. Receiving apparatuses only process and receive multicast data corresponding to their current area, rather than processing all multicast data from all areas. This segmentation reduces the processing load while maintaining comprehensive area coverage through coordinated transmission from multiple base stations.
2Adaptability or versatility
If multicast data is transmitted to all areas regardless of relevance, then data availability is improved, but resource allocation efficiency deteriorates
Solution Approach 1:
The system applies local quality by making multicast data transmission area-specific rather than universal. Each base station transmits multicast data tagged with area identification information relevant only to its local geographical area. Receiving apparatuses filter and process only the locally relevant data, improving resource allocation efficiency while maintaining data availability for all areas through the distributed base station network.
3Loss of information
If receiving apparatuses process all multicast data from all areas, then information completeness is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary action by tagging multicast data with area identification information before transmission. Receiving apparatuses use this pre-applied tagging to efficiently filter and select only the data relevant to their current area, avoiding the need to process all multicast data. This preliminary classification maintains information completeness for each local area while significantly reducing processing complexity.

AI summary
A communication apparatus according to one embodiment includes a receiver configured to receive predetermined information from a base station. The predetermined information indicates a corresponding relationship between identification information for identifying multicast data and area identification information for identifying a geographical area. The receiver is configured to receive predetermined multicast data from the base station based on the predetermined information. The predetermined multicast data includes data from another communication apparatus in a first area in which the communication apparatus is located.
