BRDMA Resource Allocation via Dynamic BRBG and RC Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resource allocation and management methods do not effectively address the needs for Block Repeat Division Multiple Access (BRDMA) systems, leading to inefficiencies in resource utilization and communication reliability, especially in scenarios with co-channel interference between adjacent cells.
Innovation Solution
A BRDMA-based resource allocation and management method that selects and allocates Block Repeat Resource Block Groups (BRBGs) with appropriate Repeat Factors (RF) and assigns Repeat Codes (RC) sequences to ensure service requirements are met, while adjusting the number of Block Repeat Blocks (BRBs) based on operating environments to balance communication reliability and cell capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Block Repeat Division Multiple Access is used to reduce co-channel interference and improve communication reliability, then communication reliability is improved, but resource utilization efficiency deteriorates due to lack of explicit resource allocation methods
Solution Approach 1:
The patent segments time-frequency resources into Block Repeat Resource Block Groups (BRBGs) with different Repeat Factors, allowing differentiated resource allocation for different users and services. This segmentation enables efficient resource utilization while maintaining the interference reduction benefits of BRDMA.
Solution Approach 2:
The patent implements dynamic resource allocation where the base station dynamically selects and allocates BRBGs with appropriate Repeat Factors based on real-time channel conditions, user requirements, and system load. This dynamic approach optimizes resource utilization efficiency while ensuring communication reliability.
2Reliability
If Repeat Factor is increased to improve service quality and reduce interference, then service quality is improved, but cell capacity deteriorates due to increased resource consumption
Solution Approach 1:
The patent applies different Repeat Factors to different Block Repeat Resource Block Groups allocated to different users or different parts of the same user's data. Users with poor channel conditions receive higher Repeat Factors for better reliability, while users with good conditions use lower Repeat Factors to conserve resources, thus maintaining cell capacity.
Solution Approach 2:
The patent changes the Repeat Factor parameter dynamically based on channel quality indicators, user mobility, and service requirements. This parameter adaptation allows the system to optimize the trade-off between service quality and cell capacity by using higher Repeat Factors only when necessary.
3Productivity
If dynamic allocation and adjustment of BRBGs and RC sequences is implemented to balance communication reliability and cell capacity, then resource utilization is enhanced, but system complexity increases
Solution Approach 1:
The patent pre-defines multiple Block Repeat Resource Block Groups with different Repeat Factors and pre-generates Repeat Code sequences. This preliminary preparation reduces the complexity of real-time resource allocation, as the base station only needs to select from pre-configured options rather than creating resources dynamically.
Solution Approach 2:
The patent implements feedback mechanisms where user equipment reports channel quality and reception status, allowing the base station to adjust BRBG allocation and RC sequence selection based on actual system performance. This feedback-driven approach optimizes resource utilization while keeping system complexity manageable through iterative refinement.
