User Apparatus Resource Allocation for D2D Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In D2D communication technologies, such as V2X, the method of allocating separate resource pools for control information and data can lead to increased overhead and delay, especially in high-speed scenarios, making it difficult to satisfy the required conditions for data transmission and reception.
Innovation Solution
A user apparatus that divides messages containing control information and data into partial messages and allocates resources from one or more resource pools to these partial messages, allowing for efficient transmission and reception of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate resource pools are allocated for control information and data in D2D communication, then resource management is simplified, but overhead increases and transmission delay increases
Solution Approach 1:
The patent combines control information and data into a single resource pool for allocation, rather than maintaining separate resource pools. This merging approach reduces the overhead associated with managing multiple resource pools and their respective signaling, while still enabling efficient D2D communication. The base station allocates resources from a unified pool, reducing control signaling overhead and simplifying resource management.
Solution Approach 2:
The patent creates a universal resource pool that serves multiple purposes - both control information and data can be allocated from the same resource pool. This multi-functional approach allows flexible resource allocation where the same pool can adaptively allocate resources to different types of traffic (control or data) based on current needs, reducing the overhead of maintaining separate specialized pools.
2Device complexity
If separate resource pools are allocated for control information and data in D2D communication, then resource allocation is structured, but transmission delay increases
Solution Approach 1:
By merging control information and data allocation into a single resource pool, the patent eliminates the sequential processing delays associated with separate pool allocations. The unified pool allows simultaneous consideration of both control and data resource needs, reducing the time required for resource allocation decisions and enabling faster transmission, which is critical for V2X applications.
Solution Approach 2:
The patent implements dynamic resource allocation from a unified pool that can adapt its allocation strategy in real-time based on traffic conditions. This dynamic approach allows the system to prioritize control information when needed while maintaining the ability to allocate data resources efficiently, reducing transmission delays compared to static separate pool allocations.
3Ease of operation
If separate resource pools are used for control information and data, then resource management is easier, but overhead increases making V2X requirements unsatisfiable
Solution Approach 1:
The patent merges control information and data resource management into a unified allocation process, reducing the overhead associated with managing separate resource pools. This approach maintains ease of operation through centralized control while significantly reducing the signaling overhead and resource waste, enabling V2X applications with their stringent overhead requirements.
Solution Approach 2:
The patent changes the fundamental parameter of resource pool structure from multiple separate pools to a single unified pool. This parameter change reduces overhead by eliminating redundant signaling and management structures, while the flexible allocation mechanisms within the unified pool maintain operational simplicity.

AI summary
A user apparatus in a mobile communication system includes an allocation means that divides a message that includes control information and data into a plurality of partial messages, and allocates resources included in one or more resource pools to the plurality of partial messages; and a transmission means that transmits the plurality of partial messages using the resources allocated by the allocation means.
