Non-Uniform Reference Signal Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating and transmitting reference signals in wireless communication systems are resource-intensive and inefficient, particularly in assigning uniform comb-type structures for reference signal resources, which limits data throughput and beamforming capabilities.
Innovation Solution
The system employs non-uniformly distributed frequencies and time slots for reference signals, assigned by a base station to user equipment using a novel resource assignment technique, allowing for sparse resource allocation and improved channel estimation and beamforming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform comb-type structures are used for reference signal resources, then the system structure is simple and easy to implement, but the data throughput is limited and bandwidth usage is inefficient
Solution Approach 1:
The patent applies local quality by transitioning from uniform comb-type structures to non-uniformly distributed reference signals. Different parts of the frequency spectrum are allocated differently based on local channel conditions and requirements. The base station assigns specific non-uniform frequency patterns to different user equipment, allowing each user to have optimized reference signal distribution tailored to their specific needs, thereby improving throughput while maintaining implementation feasibility through standardized non-uniform pattern definitions
2Ease of manufacture
If uniform comb-type structures are used for reference signals, then resource allocation is straightforward, but beamforming capabilities are limited
Solution Approach 1:
The patent implements dynamics by enabling the base station to dynamically assign non-uniform frequency patterns to different user equipment based on real-time channel conditions and beamforming requirements. Instead of static uniform comb-type structures, the system can adapt reference signal distribution to support multiple beams and dynamic resource allocation, improving beamforming capability while maintaining ease of assignment through standardized non-uniform pattern configurations
3Productivity
If non-uniformly distributed frequencies are used for reference signals, then bandwidth usage is reduced and data throughput is enhanced, but the complexity of resource assignment increases
Solution Approach 1:
The patent applies parameter changes by defining non-uniform frequency patterns through standardized parameters such as frequency offsets, spacing factors, and pattern indices. The base station assigns these parameter-based patterns to user equipment, which simplifies the complexity management. The non-uniform distribution is achieved through systematic parameter variation rather than ad-hoc frequency selection, maintaining manageable assignment complexity while achieving improved bandwidth efficiency and throughput
