Reference Signal Configuration for 5G Service Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems struggle to support various service types, numerical configurations, and multiple access modes due to symmetric reference signal allocation, which limits their ability to adapt to different system frequencies and access modes in 5G mobile communication systems.
Innovation Solution
A method for configuring a reference signal configuration parameter, including frequency-domain density, minimum frequency domain resource allocation units, and resource occupation symbol identifiers, is implemented to enable the reference signal to support various service types, numerical configurations, and multiple access modes by dynamically configuring these parameters for User Equipment (UE) through a network side device.

Engineering Contradiction Analysis
1Adaptability or versatility
If symmetric reference signal allocation is used, then the reference signal can be transmitted in conventional communication systems, but the system cannot adapt to various service types, numerical configurations and multiple access modes in 5G mobile communication systems
Solution Approach 1:
The patent applies dynamics by making the reference signal configuration parameters (frequency-domain density, minimum frequency domain resource allocation unit, resource occupation symbol identifier) adjustable and flexible. The network side device can dynamically configure these parameters based on different service types, numerical configurations, and multiple access modes, allowing the reference signal to adapt to various 5G communication scenarios rather than using a fixed symmetric allocation pattern.
Solution Approach 2:
The patent changes the parameters of the reference signal configuration by introducing frequency-domain density, minimum frequency domain resource allocation unit, and resource occupation symbol identifier as configurable parameters. These parameters can be adjusted according to different communication needs, enabling the reference signal to support diverse service types and access modes while maintaining manageable configuration complexity through structured parameterization.
2Adaptability or versatility
If the reference signal configuration parameters are dynamically configured, then the system can support various service types and multiple access modes, but the configuration process becomes more complex
Solution Approach 1:
The patent segments the reference signal configuration into distinct parameters: frequency-domain density, minimum frequency domain resource allocation unit, and resource occupation symbol identifier. This segmentation allows each parameter to be independently configured and optimized for different service types and access modes, making the overall configuration process more manageable and systematic despite the increased adaptability requirements.
Solution Approach 2:
The network side device acts as an intermediary that handles the dynamic configuration of reference signal parameters. By centralizing the configuration function in the network side device, the patent simplifies the configuration process for user equipment while maintaining the ability to support various service types and multiple access modes through network-controlled parameter adjustment.
