Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently using bandwidths, especially in high-density environments where multiple terminals and base terminals need to communicate simultaneously.
Innovation Solution
A wireless communication terminal that performs a contention procedure in each of a plurality of channels, selecting a random value within a contention window to access available channels, thereby efficiently utilizing multiple channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single channel is used for wireless communication, then device complexity is reduced, but bandwidth utilization and data communication efficiency deteriorate in high-density environments
Solution Approach 1:
The patent segments the wireless communication system into multiple independent channels (first channel and second channel). The terminal performs separate contention procedures on each channel, allowing parallel data transmission across multiple channels. This segmentation enables the system to achieve higher overall bandwidth utilization and data communication efficiency by distributing traffic across multiple channels rather than congesting a single channel.
2Productivity
If multiple channels are accessed simultaneously, then bandwidth utilization improves, but the probability of data collision and transmission error increases
Solution Approach 1:
The patent implements preliminary actions by performing contention procedures on multiple channels before actual data transmission. The terminal selects random values within contention window ranges for each channel and performs backoff counting independently on each channel. This preliminary channel access preparation ensures that when data transmission begins, the terminal has already secured reliable access to multiple channels, reducing the probability of collisions and transmission errors while maintaining high bandwidth utilization.
3Reliability
If contention window range is increased to reduce collision probability, then data transmission reliability improves, but access time and latency increase
Solution Approach 1:
The patent transitions from a single-dimensional channel access approach to a multi-dimensional approach by operating on multiple channels simultaneously. Instead of increasing the contention window range on a single channel (which increases access time), the terminal performs independent contention procedures on multiple channels with smaller contention window ranges. This dimensional change allows the system to achieve collision avoidance through channel diversity rather than through time-based backoff extension, thereby maintaining lower access latency while improving reliability.
