Wireless Control Information Arrangement for Throughput Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing control information during frame exchanges, particularly in multi-link communications, which can lead to interference and reduced system throughput.
Innovation Solution
A method and apparatus for wireless communications where a controller determines an arrangement of control information, including in-device interference information, power saving information, sub-band switch information, and transmitter/receiver parameter negotiation, and a wireless transceiver announces this arrangement in a first frame exchange and conducts subsequent exchanges based on it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control information is transmitted in every frame exchange, then communication reliability is improved, but system throughput deteriorates due to increased overhead
Solution Approach 1:
The patent segments control information transmission by dividing frame exchanges into different phases: initial frame exchanges include control information, while subsequent frame exchanges within the same TXOP omit control information. This segmentation allows reliable control information delivery when needed while maximizing throughput during data transmission phases.
Solution Approach 2:
The patent implements preliminary action by establishing control information arrangements during initial frame exchanges before actual data transmission begins. The TXOP holder announces control information arrangements (such as power saving, sub-band switch, and Tx/Rx parameter information) in advance, allowing both devices to optimize subsequent communications without repeated control information overhead.
2Adaptability or versatility
If dynamic parameter negotiation is implemented for each TXOP responder, then communication adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by implementing per-TXOP-responder parameter negotiations where each responder receives customized control information arrangements tailored to its specific requirements. The TXOP holder can differentially set power saving modes, sub-band switches, and Tx/Rx parameters for different responders, optimizing communication for each local context without requiring complex global coordination.
