Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of backscatter communication systems with existing new radio (NR) systems leads to conflicts, affecting communication performance due to unconsidered impacts on NR channel or signal transmission.
Innovation Solution
A conflict processing method and apparatus that prioritize and manage the transmission of information in backscatter communication systems to avoid conflicts with NR systems, either by discarding the transmission of conflicting information or by allocating transmission resources based on determined priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If backscatter communication system transmits information using NR channels, then communication functionality is enhanced, but transmission conflicts with NR channels occur affecting communication performance
Solution Approach 1:
The patent applies preliminary action by having the backscatter communication device determine transmission priorities of NR channels before actual transmission occurs. The device proactively identifies potential conflicts and pre-determines which channels should be transmitted first, avoiding conflicts rather than resolving them during transmission. This is implemented through priority determination based on channel types, transmission directions, and time domain relationships before the actual backscatter transmission happens.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting transmission priorities based on varying conditions such as channel types (control channels vs. data channels), transmission directions (downlink vs. uplink), and time domain relationships. The priority values are not fixed but change according to these parameters, allowing the system to adapt to different transmission scenarios and resolve conflicts optimally under varying operational conditions.
2Reliability
If transmission priority is determined for conflict resolution, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex priority determination into multiple independent aspects: channel type classification (control channels, data channels, reference signals), transmission direction identification (downlink, uplink, sidelink), and time domain relationship analysis. Each aspect can be evaluated separately and combined to determine overall priority, making the complex decision process more manageable and implementable through modular logic.
Solution Approach 2:
The patent uses parameter changes to simplify the complexity management by establishing clear rules for how priority values change based on identifiable parameters. Instead of complex algorithms, the system uses parameter-based rules such as 'control channels have higher priority than data channels,' 'downlink transmissions take precedence over uplink,' and 'overlapping time domains require priority resolution.' These parameter-based rules make the complexity more structured and easier to implement.
Data Source
AI summary
This application discloses a conflict processing method, a terminal, and a network side device. The conflict processing method includes: performing, by a first device, a target operation in a case that there is a conflict between transmission of first information and transmission of second information. The target operation includes discarding the transmission of the first information or discarding the transmission of the second information, the first information includes information carried in a channel or a signal of a backscatter communication system, and the second information includes information other than the first information.
