Communication Group TDM Scheduling to Reduce Wireless Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-communication group systems, wireless communication between devices often suffers from interference due to the use of the same wireless transmission method by different groups, leading to poor flexibility and high costs, especially in scenarios like Internet of Vehicles, in-vehicle, family, and wearable devices.
Innovation Solution
Implementing time-division multiplexing (TDM) to allocate distinct time-domain resources to different communication groups, ensuring they communicate at different times to avoid interference and improve performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication groups use the same wireless transmission method in the same carrier, then wireless communication flexibility is improved, but interference between communication groups occurs
Solution Approach 1:
The patent segments the time-domain resources by dividing them into multiple communication group-specific time resources. Each communication group is assigned dedicated time slots (first time-domain resource for first group, second time-domain resource for second group), preventing simultaneous transmissions that cause interference while maintaining wireless flexibility.
Solution Approach 2:
The patent implements periodic time-division multiplexing where communication groups transmit in alternating time slots. The first communication group transmits during its allocated time period, then the second communication group transmits during its allocated time period, creating a periodic pattern that eliminates interference while enabling continuous wireless communication.
2Ease of operation
If wireless communication is used instead of wire, then flexibility is improved, but interference between groups occurs due to shared transmission methods
Solution Approach 1:
The patent segments time-domain resources into group-specific allocations, giving each wireless communication group dedicated time slots. This segmentation allows wireless communication to maintain its flexibility advantage over wired connections while eliminating interference through temporal separation of transmissions.
Solution Approach 2:
The patent establishes periodic transmission patterns where communication groups alternate in using the wireless medium. This periodic action enables wireless communication flexibility while preventing simultaneous transmissions that would cause interference between groups.

AI summary
The present application provides a communication method, apparatus and device and a storage medium. A first communication device determines a first time-domain resource used by a first communication group where the first communication device is located, and communicates with other communication devices in the first communication group by using the first time-domain resource. The first time-domain resource used by the first communication group is different from a second time-domain resource used by a second communication group, and the first communication group and the second communication group are any two of a plurality of communication groups coexisting in a target communication system; thus, the use of different time-domain resources for communication among communication devices in the plurality of communication groups coexisting in the target communication system effectively avoids interferences among the communication groups and improves the communication performance among the communication devices.
