Adaptive Control Channel Overhead Management in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation wireless communication networks, such as 5G, face challenges in reducing control channel overhead, which increases signaling overhead and reduces data transmission resources, thereby limiting throughput and capacity.
Innovation Solution
The implementation of an overhead management component that determines the redundancy version state for control channel transmission based on device characteristics, such as speed and service type, to optimize the inclusion of redundancy version information, thereby reducing control channel overhead and enhancing power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundancy version information is always included in control channel transmission, then reliability of data transmission is improved, but control channel overhead increases
Solution Approach 1:
The patent applies dynamics by making the control channel format adaptive rather than static. The network device dynamically selects between first and second control channel formats based on device characteristics (speed, service type), allowing the system to optimize between reliability and overhead in real-time根据不同场景调整控制信息
Solution Approach 2:
The patent applies local quality by differentiating control channel transmission based on specific device characteristics. High-speed devices or devices with specific service requirements receive control channels with redundancy version information (first format), while other devices receive control channels without such information (second format), tailoring the quality of control information to local needs
2Productivity
If control channel overhead is reduced, then data transmission resources increase, but reliability of control information transmission may deteriorate
Solution Approach 1:
The patent applies parameter changes by modifying the control channel format parameters based on device characteristics. The network device changes the parameter of redundancy version information inclusion according to device speed and service type, optimizing the balance between control channel overhead and reliability for different scenarios
Solution Approach 2:
The system dynamically adjusts the control channel format to match transmission conditions. For high-speed devices where reliability is critical, the first format with redundancy version information is used. For other devices, the second format with reduced overhead is used, making the system adaptive to different operational requirements

AI summary
Controlling and reducing overhead in control channels in 5G or other next generation communication systems is provided herein. In connection with a data transmission between a device and a network node device, an overhead management component (OMC) can analyze one or more factors associated with the device, including speed or Doppler metric(s) of the device, type of service associated with the device, historical HARQ statistics for the device, configured threshold value for CSI estimation, device capability regarding redundancy version support, or another factor(s). Based on analysis results, OMC can determine whether to utilize a single redundancy version state or a multiple redundancy versions state. If the single redundancy version state is selected, OMC can generate control information that does not include redundancy version information, the control information being communicated via a control channel OMC can communicate RRC signal to the device to indicate the determined redundancy version state.
