Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face interference issues during non-scheduling periods in terminal devices, particularly in LTE systems, where operations like data retransmission and scheduling requests can disrupt other communication modes, and current solutions do not adequately address these interferences.
Innovation Solution
A terminal device and method that receive control signaling from a base station to stop specific operations within non-scheduling periods, such as DRX retransmission and scheduling requests, to reduce interference, and optionally send interference frequency instructions to switch to frequencies that minimize cross-system interference.

1Productivity
If data transmission operations are conducted within the non-scheduling period (such as data retransmission and scheduling request transmission), then communication efficiency is improved, but interference on other communication modes occurs
Solution Approach 1:
The patent segments the non-scheduling period into multiple sub-periods, allowing different types of operations to be performed in different sub-periods. This segmentation enables the terminal to conduct data retransmission in one sub-period while avoiding scheduling request transmissions in another sub-period, thereby reducing interference on other communication modes while maintaining overall communication efficiency
Solution Approach 2:
The patent dynamically adjusts the terminal's operation behavior based on real-time conditions. By receiving control signaling from the base station that indicates whether scheduling request transmissions should be performed in the non-scheduling period, the terminal can adapt its transmission strategy dynamically - performing operations when appropriate and avoiding them when they would cause interference, thus balancing communication efficiency with interference reduction
2Object-affected harmful factors
If TDM scheme divides communication into scheduling period and non-scheduling period using DRX mechanism, then interference between adjacent frequency ranges is reduced, but data transmission operations in non-scheduling period still cause interference
Solution Approach 1:
The patent further segments the non-scheduling period into multiple sub-periods and selectively permits or prohibits scheduling request transmissions in specific sub-periods based on control signaling from the base station. This refined segmentation allows the system to maintain the interference-reducing benefits of TDM while eliminating residual interference caused by operations in the non-scheduling period
Solution Approach 2:
The patent implements a feedback mechanism where the base station monitors the terminal's operations and sends control signaling to adjust the terminal's behavior in the non-scheduling period. This feedback loop enables the base station to detect when interference is occurring and instruct the terminal to adjust its transmission strategy, thereby continuously optimizing the balance between communication efficiency and interference reduction

AI summary
Embodiments of the present invention disclose a terminal device and a method thereof for reducing interference in a device, which belong to the field of interference processing. The method includes: receiving a control signaling for interference processing sent by a base station; and according to the control signaling, stopping a related operation within a non-scheduling period of a communication mode corresponding to the control signaling. The terminal device includes: a receiving module, and a stopping module. The embodiments of the present invention enable other communication modes to carry out data transmission within the non-scheduling period of the communication mode corresponding to the control signaling, by way of stopping by the terminal device a related operation within the non-scheduling period of the communication mode corresponding to the control signaling according to the control signaling for interference processing sent by the base station. This reduces the interference to the other communication modes due to the communication mode corresponding to the control signaling within the non-scheduling period, and thus reduces interference in the terminal device within the non-scheduling period.
