Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication technologies, the fixed maximum resource block allocation based on channel bandwidth leads to low spectrum utilization due to varying transmission capabilities among terminal devices using the same channel bandwidth.
Innovation Solution
Determining the maximum number of transmission resource blocks for a terminal device based on its reported capability information and configuring resource blocks accordingly to optimize resource allocation and improve spectrum utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If maximum resource block allocation is fixed based on channel bandwidth, then resource allocation is simple and standardized, but spectrum utilization is low due to varying terminal device capabilities
Solution Approach 1:
The patent transforms the fixed resource block allocation into a dynamic configuration based on terminal device capability. The network device determines the maximum number of transmission resource blocks according to capability information reported by the terminal device, allowing the allocation to adapt to different terminal capabilities while maintaining standardized procedures.
Solution Approach 2:
The patent changes the allocation parameter from a fixed value based solely on channel bandwidth to a variable value that incorporates terminal device capability information. This parameter change enables the system to optimize spectrum utilization by tailoring resource block allocation to individual terminal capabilities.
2Adaptability or versatility
If resource blocks are allocated based on channel bandwidth only, then configuration is standardized, but it leads to resource wastage for terminals with lower transmission capabilities
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device reports its capability information to the network device. The network device then uses this feedback to determine the appropriate maximum number of transmission resource blocks, ensuring that resource allocation matches actual terminal capabilities and avoids wastage.
Solution Approach 2:
The patent applies local quality by tailoring resource block allocation to individual terminal device capabilities rather than applying a uniform standard. Each terminal receives resource block configuration customized to its specific transmission capabilities, optimizing resource utilization while maintaining standardized configuration procedures.
