Wireless Communication Device Data Buffering for Transmission Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face inefficiencies due to high processing speed requirements and the need for re-transmitting payload data, which is time-consuming and costly.
Innovation Solution
A wireless communication method that employs a data processing chip with a data buffer, utilizing a combination of store-and-forward and cut-through modes to pre-fetch and transmit payload data, reducing processing speed demands and avoiding re-fetch during re-transmissions by buffering partial payload in the data buffer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the component operates at high processing speed to meet data transmission requirements, then the data transmission performance is improved, but the cost of the wireless communication device increases
Solution Approach 1:
The patent applies preliminary action by pre-fetching payload data into the data buffer before actual transmission occurs. The component transitions to an active state, pre-fetches a portion of the payload from the host, then transitions to inactive state. When re-transmission is needed, the buffered data is immediately available without requiring the component to re-process or re-fetch the entire payload, thereby reducing processing speed requirements and associated costs while maintaining transmission performance.
2Reliability
If the component re-transmits payload data from scratch, then data reliability is maintained, but the time consumption increases
Solution Approach 1:
The component pre-fetches payload data into the data buffer during an initial active state before transmission begins. When transmission failure occurs and re-transmission is required, the component can immediately access the pre-buffered data without re-fetching from the host, significantly reducing re-transmission time while maintaining data reliability through the buffered copy.
Solution Approach 2:
The data buffer acts as an intermediary between the host and the antenna. Instead of directly fetching data from the host during re-transmission, the component uses the pre-filled data buffer as an intermediate storage, eliminating the time-consuming re-fetch operation while ensuring data integrity for re-transmission.
3Manufacturing precision
If the component continuously monitors and processes all payload data, then data transmission accuracy is improved, but the processing speed requirement increases
Solution Approach 1:
The patent segments the payload data into portions that can be pre-fetched and buffered. The component pre-fetches only the necessary portion of payload data into the data buffer during the initial active state, then transitions to inactive state. This segmentation allows the component to maintain accuracy by having complete data available in the buffer while reducing processing speed requirements by not needing to continuously monitor and process the entire payload stream in real-time during re-transmission.
Data Source
AI summary
The application provides a wireless communication method and a wireless communication device. A part of payload is pre-fetched from a host to a data buffer under a store-and-forward mode before transmission begins. When data transmission begins, the part of the payload pre-fetched in the data buffer is transmitted to an antenna. A remaining part of the payload is fetched to the data buffer under a cut-through mode for payload transmission, wherein the remaining part of the payload is sent from the data buffer to the antenna for radiation.
