Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices face high power consumption during data transmission, which shortens battery life without compromising data quality, and existing methods fail to optimize energy efficiency effectively.
Innovation Solution
A method that selects between two transmission modes: one with more communication resources for shorter intervals and another with fewer resources for longer intervals, allowing data to be buffered and sent in bursts, optimizing power consumption by adjusting the time interval between data transmissions based on measured round trip time.

Engineering Contradiction Analysis
1Reliability
If data is transmitted continuously using available communication resources, then data transmission quality is maintained, but power consumption increases
Solution Approach 1:
The patent implements discontinuous transmission by periodically activating the transmitter only when data is available for transmission, rather than maintaining continuous operation. The transmitter is switched off during time periods when no data needs to be sent, creating a periodic on-off pattern that reduces power consumption while maintaining data transmission quality when active.
Solution Approach 2:
The patent buffers data in a data buffer before transmission, holding data until transmission conditions are favorable or data is ready. This buffering approach allows the system to discard continuous transmission and recover energy by switching the transmitter off, then transmit the buffered data in concentrated periods when power is consumed.
2Use of energy by moving object
If transmitter is switched off for longer periods to save power, then energy consumption decreases, but data transmission delay increases
Solution Approach 1:
The patent performs preliminary buffering of data in the data buffer before transmission is needed. By preparing data in advance and storing it in the buffer, the system can switch the transmitter off for longer periods without incurring transmission delays, as the data is already ready and waiting for transmission opportunities.
Solution Approach 2:
The patent dynamically adjusts the transmission timing based on data availability and buffer status. The transmitter activation is not fixed but adapts to real-time conditions, allowing longer off periods when data accumulation in the buffer justifies it, while maintaining acceptable delay performance by transmitting as soon as data is ready and resources are available.
3Use of energy by moving object
If data is buffered and transmitted in bursts, then power consumption is reduced, but communication resource allocation efficiency decreases
Solution Approach 1:
The patent employs feedback mechanisms where the transmitter and receiver coordinate transmission timing and resource allocation. The receiver provides feedback about data reception status and timing, allowing the transmitter to optimize burst transmission timing and resource usage, improving overall system efficiency despite the discontinuous transmission pattern.

AI summary
A method of transmitting data is described comprising selecting a transmission mode from at least a first and a second transmission mode, wherein according to the first transmission mode data is transmitted in at least two first time periods using first communication resources wherein the at least two first time periods are separated by a first time interval, wherein according to the second transmission mode data is transmitted in at least two second time periods using second communication resources wherein the at least two second time periods are separated by a second time interval, and wherein the first time interval is longer than the second and the first communication resources allow the transmission of a higher amount of data than the second communication resources; and transmitting data according to the selected transmission mode.
