Wireless Communication Channel Segmentation for Stable Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, devices face instability in transmitting high-capacity data due to contention with multiple devices for channel access, leading to degraded transmission performance, especially when multiple devices are nearby and competing for limited resources.
Innovation Solution
The method involves dividing communication periods into specific intervals to communicate with a particular predetermined device using low power, allowing stable communication without interfering with other devices, and utilizing channel resources occupied by unspecified devices to maintain connectivity, while reducing overhead by designing antennas for dedicated communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device performs contention-based wireless channel access to communicate with another device at short range, then the device can access the wireless channel through contention with other devices, but the transmission performance degrades when multiple devices compete for limited channel resources
Solution Approach 1:
The patent segments the communication approach into two distinct modes: contention-based access for general devices and dedicated resources for particular devices. This segmentation allows the system to simultaneously support both ad-hoc communication and reliable high-capacity data transmission by assigning different access mechanisms to different communication scenarios.
Solution Approach 2:
The patent changes the parameter of channel access from dynamic contention-based to static dedicated allocation for particular devices. By transforming the access mode parameter, the system ensures that high-capacity data transmission is not affected by channel contention, thereby improving transmission performance and reliability.
2Adaptability or versatility
If multiple devices are located at short range and desire to access the wireless channel, then channel access becomes more competitive, but the ratio of resources available to each device decreases
Solution Approach 1:
The patent implements a universal channel access mechanism that serves multiple functions: contention-based access for general devices and dedicated resource allocation for particular devices. This multi-functionality allows the system to adapt to different communication needs while ensuring that high-capacity data transmission always has sufficient resources available.
3Reliability
If a device needs to transmit high-capacity data with very high QoS requirements, then seamless transmission is required, but contention with multiple devices causes transmission instability
Solution Approach 1:
The patent applies preliminary action by pre-allocating dedicated channel resources for particular devices before high-capacity data transmission begins. This advance preparation ensures that when high-capacity data needs to be transmitted, the required resources are already reserved and available, eliminating the instability caused by contention and enabling seamless transmission.
