Solution Overview
Problem
Current wireless communication standards lack a unified solution to efficiently support both high data rates and low latency in unlicensed frequency bands like 2.4 GHz, 5 GHz, and 6 GHz.
Innovation Solution
A method and apparatus in a wireless communication device that dynamically selects between Listen Before Talk (LBT) and Frequency Hopping (FH) channel access mechanisms based on data properties such as bandwidth and latency requirements, allowing for flexible channel access to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If LBT is used with large channel bandwidth to support high data rates, then data rate is improved, but access delay increases
Solution Approach 1:
The patent applies dynamics by making the channel access mechanism selectable based on data characteristics. The system dynamically switches between LBT and FH mechanisms depending on whether the data requires high data rate or low latency, allowing the system to adapt its behavior rather than being fixed to one mechanism
Solution Approach 2:
The patent changes the parameter of channel access mechanism selection based on data properties. By monitoring data characteristics (such as latency requirements or data rate needs), the system adjusts the access mechanism parameter to match the specific transmission requirements, optimizing performance for each case
2Loss of time
If FH is used with small channel bandwidth to meet latency requirements, then access delay is reduced, but data rate decreases
Solution Approach 1:
The system dynamically adapts the channel access mechanism based on the specific data transmission requirements. When low latency is needed, FH is activated; when high data rate is the priority, LBT is used. This dynamic adaptation allows the system to optimize for different performance goals without being constrained to a single mechanism
Solution Approach 2:
The patent changes the operational parameters by selecting different channel access mechanisms based on data properties. The system monitors characteristics of the data to be transmitted and adjusts the access mechanism parameter accordingly, switching between FH and LBT to match the performance requirements
3Device complexity
If a single channel access mechanism is used for all data types, then system complexity is reduced, but performance optimization is lost
Solution Approach 1:
The patent applies local quality by tailoring the channel access mechanism to the specific characteristics of each data type. Instead of using a uniform mechanism for all data, the system identifies local requirements (latency-sensitive vs. throughput-sensitive) and applies the appropriate mechanism locally, optimizing performance for each data type while maintaining overall system manageability
