Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In burst interference systems, conventional cellular communication methods fail to adapt channel encoding based on interference conditions, leading to inefficiencies due to high-power burst interference sources.
Innovation Solution
A control device dynamically configures channel encoding manners for semi-static scheduling configurations, transport blocks within specific bit ranges, and downlink control channels based on current time, geographic position, and channel interference conditions, using polar, LDPC, or Reed-Solomon encoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cellular communication encoding methods are used, then the system maintains standard compatibility, but the system fails to resist high-power burst interference
Solution Approach 1:
The patent implements dynamic channel encoding by selecting different encoding schemes (polar, LDPC, Reed-Solomon) based on real-time interference conditions, geographic position, and time. The control device determines the appropriate encoding manner adaptively rather than using a fixed conventional encoding method, thereby resolving the contradiction between maintaining standard compatibility and achieving interference resilience.
Solution Approach 2:
The patent changes the encoding parameters dynamically by selecting from multiple encoding schemes based on interference level thresholds, time of day, and geographic location. When burst interference is detected above a threshold, the system switches to more robust encoding schemes like Reed-Solomon, thereby improving anti-interference capability while maintaining adaptability to different operational conditions.
2Reliability
If dynamic encoding configuration is implemented, then anti-interference capability is improved, but system complexity increases
Solution Approach 1:
The patent pre-configures multiple encoding schemes (polar, LDPC, Reed-Solomon) and establishes interference threshold levels in advance. The control device has pre-prepared encoding configurations that can be quickly selected based on current conditions, avoiding the need for complex real-time encoding decisions and reducing system complexity while maintaining communication resilience.
Solution Approach 2:
The system implements feedback mechanisms where the control device monitors interference conditions, determines appropriate encoding schemes, and sends configuration information back to terminal devices. This closed-loop feedback approach automates the encoding selection process, improving communication resilience without requiring complex manual configuration or decision-making at the terminal side.
3Productivity
If encoding is optimized for interference conditions, then communication efficiency under interference improves, but processing overhead increases
Solution Approach 1:
The patent applies different encoding schemes to different channels and data types based on their specific requirements. For example, downlink control channels may use polar encoding under normal conditions, while data channels experiencing burst interference switch to Reed-Solomon encoding. This localized optimization improves communication efficiency under interference without requiring all channels to undergo complex encoding decisions, thereby reducing overall processing overhead.

AI summary
Provided are a channel encoding method and a control device. In the channel encoding method, a control device sends configuration information to a controlled device, wherein the configuration information is used for configuring one of the following: a channel encoding manner corresponding to at least one semi-persistent scheduling configuration; a channel encoding manner corresponding to a first transport block, with the number of bits of the first transport block being less than a first threshold value and greater than a second threshold value; and a channel encoding manner corresponding to a first downlink control channel.
