Reduced Interframe Spacing in Wireless Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in frame throughput due to overhead from processing and transmission of frames, particularly in the handling of physical and medium access control layer information, which results in increased time and processing requirements for acknowledging and setting up each frame.
Innovation Solution
Implementing a reduced interframe spacing (RIFS) interval and suppressing acknowledgment responses to decrease the time between frame transmissions, allowing the existing PHY layer configuration to be sustained for subsequent frames without requiring a teardown and setup process, thereby enhancing data throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional interframe spacing is used to ensure proper PHY layer setup and acknowledgment, then transmission reliability is maintained, but frame throughput decreases due to increased time overhead between frames
Solution Approach 1:
The patent extracts and removes the acknowledgment response mechanism from the traditional frame transmission sequence. By suppressing ACK frames and eliminating the teardown/setup process between frames, the system eliminates the time-consuming acknowledgment phase while maintaining throughput through continuous transmission modes
Solution Approach 2:
The patent performs preliminary configuration by establishing PHY layer settings before frame transmission begins. The transceiver is pre-configured with transmission parameters, power levels, and modulation schemes, allowing frames to be transmitted continuously without repeated setup procedures between each frame
2Reliability
If acknowledgment responses are transmitted for each frame, then transmission reliability is improved, but system efficiency deteriorates due to increased overhead and processing time
Solution Approach 1:
The patent extracts and removes the acknowledgment response mechanism from the traditional frame transmission sequence. By suppressing ACK frames and eliminating the teardown/setup process between frames, the system eliminates the time-consuming acknowledgment phase while maintaining throughput through continuous transmission modes
Solution Approach 2:
The patent enables continuous transmission by eliminating the stop-and-wait acknowledgment protocol. Frames are transmitted in continuous bursts without interruption for ACK responses, maintaining the transmission channel in an active state and maximizing the utilization of the communication medium
3Manufacturing precision
If PHY layer teardown and setup is performed for each frame, then transmission accuracy is maintained, but device complexity increases due to repeated configuration processes
Solution Approach 1:
The patent performs preliminary configuration by establishing PHY layer settings before frame transmission begins. The transceiver is pre-configured with transmission parameters, power levels, and modulation schemes, allowing frames to be transmitted continuously without repeated setup procedures between each frame
Solution Approach 2:
The patent creates a universal transmission mode that can handle multiple frames with a single PHY layer configuration. The same configuration serves for transmitting sequences of frames, eliminating the need for frame-specific setup procedures and reducing overall system complexity
