SRS Resource Configuration for 5G Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, the transmit power of SRS resources is low due to limited frequency domain density, specifically supported only at comb-2 and comb-4 structures, which affects their effectiveness in beam management and positioning.
Innovation Solution
Distributing SRS resources at equal intervals in the frequency domain with more than 4 subcarriers, such as comb-6, comb-8, or comb-12 structures, to increase transmit power and improve frequency domain density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If SRS resources are distributed at comb-2 and comb-4 structures in frequency domain, then frequency domain density is limited, but transmit power becomes low
Solution Approach 1:
The patent changes the frequency domain density parameter from traditional comb-2 and comb-4 structures to comb-6, comb-8, or comb-12 structures. This parameter change increases the number of subcarriers allocated to SRS resources, thereby increasing both frequency domain density and transmit power simultaneously, resolving the technical contradiction.
2Power
If SRS resources are distributed at equal intervals with more than 4 subcarriers, then transmit power increases, but frequency domain density structure becomes more complex
Solution Approach 1:
The patent segments the frequency domain into multiple subcarriers and allocates SRS resources at equal intervals across these subcarriers. By using comb-6, comb-8, or comb-12 structures, the frequency domain is divided into more segments, which increases transmit power while maintaining a regular, systematic allocation pattern that manages complexity.
