Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in NR, the fixed number of symbols per slot and data symbols in existing resource allocation methods are inefficient due to varying transmission bandwidths and UE capabilities, leading to suboptimal resource utilization.
Innovation Solution
A method where a base station determines a specified number of symbols and maximum bandwidth for a UE, selects a maximum transmission block size, and performs resource allocation based on UE capability information, allowing for variable data symbol allocation and efficient use of resources in the time-frequency domain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed number of symbols per slot and fixed number of data symbols are used in resource allocation, then resource allocation is simplified, but resource utilization efficiency deteriorates due to varying transmission bandwidths and UE capabilities
Solution Approach 1:
The patent applies dynamics by making the number of data symbols variable rather than fixed. The base station determines a specified number of symbols based on UE capability information and transmission conditions, allowing the resource allocation to adapt dynamically to different scenarios while maintaining manageable complexity through structured determination methods
Solution Approach 2:
The patent changes the parameter of symbol count from a fixed value to a variable parameter determined by UE capabilities and transmission conditions. This allows the system to optimize resource utilization by adjusting the number of data symbols according to actual needs while maintaining systematic control through defined determination procedures
2Adaptability or versatility
If variable numbers of symbols are allocated for data transmission to support different services, then service adaptability is improved, but resource allocation complexity increases
Solution Approach 1:
The patent uses parameter changes by adjusting the number of data symbols based on service requirements and UE capabilities. Different services (eMBB, mMTC, URLLC) can be supported by varying the symbol count parameter while maintaining systematic control through defined determination methods that prevent complexity from becoming unmanageable
Solution Approach 2:
The patent applies dynamics by enabling the resource allocation system to adapt to different service types and UE capabilities through variable symbol allocation. The base station dynamically determines the specified number of symbols based on received UE capability information and current transmission conditions, allowing flexible service support with controlled complexity
3Adaptability or versatility
If maximum bandwidth of 400 MHz is supported to accommodate all UE capabilities, then system capability is improved, but resource allocation efficiency deteriorates for UEs with limited bandwidth
Solution Approach 1:
The patent applies local quality by tailoring the resource allocation to each UE's specific bandwidth capability. Instead of uniformly allocating resources based on maximum bandwidth, the base station determines the specified number of symbols and maximum bandwidth allocable for each UE based on their individual capabilities, optimizing resource usage for each user's actual needs
Solution Approach 2:
The patent changes the bandwidth parameter from a fixed maximum value to a variable parameter adapted to each UE's capability. The base station adjusts the maximum bandwidth allocable and specified number of symbols based on UE capability information, allowing the system to support both high-bandwidth and low-bandwidth UEs efficiently without waste
