Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio transceivers face challenges in achieving high data rates with low energy consumption due to disruptive uncoordinated or spontaneous radio signals, leading to high error rates and failed transmissions.
Innovation Solution
The radio transceiver is trained to send test radio sequences with different transmission properties and receive feedback, allowing it to select the optimal transmission properties for subsequent radio messages, such as highest data rate with lowest energy consumption.

1Productivity
If test radio sequences are transmitted with different transmission properties to select optimal transmission characteristics, then data throughput is maximized and energy consumption is minimized, but device complexity and communication overhead increase
Solution Approach 1:
The system performs preliminary transmission of test radio sequences with different transmission properties (data rates, codes, modulation types, transmission powers) before actual data transmission. The receiver evaluates these test sequences and provides feedback, allowing the transmitter to select optimal transmission characteristics in advance, thereby maximizing data throughput while minimizing energy consumption during actual communication
Solution Approach 2:
The receiver node evaluates the received test radio sequences and transmits feedback information containing reception quality metrics to the transmitter. Based on this feedback, the transmitter selects the optimal transmission property from the tested options, creating a closed-loop adaptive system that optimizes performance while managing complexity through informed decision-making
2Reliability
If multiple test radio sequences with different transmission properties are transmitted, then optimal transmission characteristics can be selected, but transmission time and energy consumption increase
Solution Approach 1:
Instead of exhaustively testing all possible transmission properties, the system transmits a limited set of representative test radio sequences with different transmission properties (data rates, codes, modulation types, transmission powers). This partial action approach finds sufficiently good transmission characteristics without the time cost of complete exhaustive search, balancing reliability improvement with time efficiency
Solution Approach 2:
The test sequence transmission and evaluation occurs as a preliminary step before actual data transmission. By determining optimal transmission characteristics in advance through this preliminary phase, the system ensures reliable transmission during the main data communication phase without repeatedly testing, thereby minimizing total channel occupancy time while maintaining high transmission reliability

AI summary
A radio transceiver for transmitting a radio message is configured to transmit a plurality of test radio sequences, wherein the radio transceiver is configured to transmit different test radio sequences with different transmission characteristics, and each transmission characteristic being one of a plurality of transmission characteristics. The radio transceiver is configured to receive feedback containing information associated with a receiver node receiving any of the plurality of test radio sequences. Based on this feedback, the radio transceiver selects a specific transmission characteristic from the plurality of transmission characteristics and transmits the radio message to the receiver node with that selected transmission characteristic.
