Aggregating Data Frames to Reduce Wireless Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmitting/receiving methods in wireless personal area networks waste power due to redundant synchronization and header sections in data frames, leading to increased transmission time and device operating time, even when data is relayed between devices with the same transmission source and destination.
Innovation Solution
A data transmitting/receiving method that reduces redundant sections by generating new synchronization and header sections, combining payloads from multiple data frames, and transmitting them as a single data frame, allowing for reduced transmission time and power consumption by shortening active periods and extending inactive sleep modes.

Engineering Contradiction Analysis
1Reliability
If data frames are sequentially relayed from lower-level device to higher-level device with individual synchronization and header sections, then each device can independently process and forward data, but the transmission time increases and power consumption increases due to redundant sections
Solution Approach 1:
The patent combines multiple data frames from different slave devices into a single aggregated data frame at the master device. Instead of each relayed frame containing its own synchronization section and header section, the master device creates one unified data frame that consolidates all payloads, eliminating redundant synchronization and header sections across multiple transmissions.
Solution Approach 2:
The master device performs multiple functions: it receives data frames from multiple slave devices, aggregates their payloads, generates a single synchronization section and header section for the aggregated data, and transmits the unified frame. This multi-functional approach replaces the need for each intermediate device to perform separate transmission operations with individual frame structures.
2Ease of operation
If individual synchronization and header sections are included in each data frame for relayed data, then each transmission is self-contained and can be processed independently, but the overall transmission time increases
Solution Approach 1:
The patent merges multiple individual data frames into a single aggregated frame at the master device. The synchronization section and header section are generated once for the aggregated frame rather than being repeated in each individual frame, significantly reducing the total transmission time while maintaining the ability to process data from multiple sources.
3Reliability
If data frames with complete synchronization and header sections are transmitted for each relayed data unit, then each frame is self-sufficient for processing, but the active period of devices must be extended
Solution Approach 1:
The master device aggregates payloads from multiple slave devices into a single data frame structure, eliminating the need for each slave device to transmit complete frames with full synchronization and header sections. This reduces the active period required for data transmission while maintaining reliable delivery through the aggregated frame structure.

AI summary
Provided is a data transmitting/receiving method capable of effectively suppressing power consumption. The data transmitting/receiving method includes: establishing synchronization between the master device and the slave device; receiving the data frame; extracting the payloads from the received data frame; generating a new payload section by combining the extracted payloads with another payload extracted from another data frame received from another device or a new payloadgenerated by the device; generating a new synchronization section and a new header section; generating a new data frame by combining the new synchronization section and the new header section that are generated with the new payload section; and transmitting the generated new data frame.
