UE IDC Interference Handling via Information Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) experiences inaccurate measurement results or connection failure reports due to in-device coexistence (IDC) interference, where transmitting and receiving modules using different radio access technologies operate on adjacent or resonant frequencies, leading to interference and affected measurement or connection failure reports.
Innovation Solution
The UE processes information by transmitting or skipping transmission of first and second information, where the first information is not affected by IDC interference and the second information is affected, with additional information indicating IDC interference presence, and network devices receive and transmit this additional information to handle the interference effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE transmits measurement results or connection failure reports, then network devices can obtain information for network optimization and connection management, but the accuracy of the reported information deteriorates due to IDC interference affecting the UE's transceiver modules
Solution Approach 1:
The patent segments the information transmission by introducing an indication field that separates affected information from unaffected information. The UE divides its report into parts: measurement results/connection failure reports that are affected by IDC interference and those that are not, allowing the network device to process only the reliable portions for decision-making
Solution Approach 2:
The patent introduces an intermediary indication field (specifically a first indication information bit) that mediates between the UE and network device. This indication field signals to the network device whether the reported measurement results or connection failure reports are affected by IDC interference, enabling the network device to adjust its processing accordingly without requiring complex interference cancellation at the UE side
2Adaptability or versatility
If UE includes multiple transceiver modules using different radio access technologies, then the UE can support multiple RATs for enhanced connectivity and functionality, but IDC interference occurs when transmitting and receiving frequencies are adjacent or resonant
Solution Approach 1:
The patent implements a feedback mechanism where the UE monitors its own transceiver operations and provides feedback to the network device through the indication field. When the UE detects that IDC interference is affecting its measurements or connection status, it sets the indication field to signal this condition, enabling the network device to receive feedback about the quality of the reported information and adjust its operations accordingly
Solution Approach 2:
The patent converts the harmful effect of IDC interference into beneficial information by using the interference condition itself as a signaling mechanism. The indication field transforms the problem of interference into a useful signal that tells the network device how to interpret the reported data, turning a negative factor into a source of operational intelligence

AI summary
Embodiments of this application disclose an information processing method, a device, and a system. A specific solution is as follows: The UE performs any one of the following processing in a case that IDC interference is present in the UE: transmitting first information, transmitting additional information, transmitting first information and additional information, transmitting first information, second information, and additional information, skipping transmitting first information, skipping transmitting second information, or skipping transmitting first information and second information, where the first information is the information provided by the UE and not affected by IDC interference, the second information is the information provided by the UE and provided by the UE and IDC interference, and the additional information is used to indicate that the UE is affected by IDC interference.
