Communication Device Adaptive Transmission Scheme Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in choosing a transmission scheme, leading to increased time in completing communications, especially when lower effective rate schemes are selected later in the order, resulting in prolonged communication times.
Innovation Solution
A control method for a communication device that adjusts the schedule to prioritize transmission schemes with a higher probability of success, advancing successful schemes earlier and delaying less successful ones, allowing for quicker communication completion.

Engineering Contradiction Analysis
1Speed
If transmission schemes are tried in descending order of effective rate, then communication speed is improved when high-rate schemes succeed, but communication time increases when low-rate schemes are selected later in the order
Solution Approach 1:
The patent dynamically adjusts the trial order of transmission schemes based on historical success/failure information. Instead of using a fixed descending order of effective rate, the system adaptively reorders schemes by combining effective rate with success probability, allowing the trial sequence to change according to actual communication conditions and terminal characteristics
Solution Approach 2:
The patent changes the parameter of trial order by calculating a composite score that combines effective rate and success probability. This transforms the static parameter (effective rate only) into a dynamic parameter (composite score) that reflects both transmission efficiency and historical performance, enabling optimized scheme selection
2Productivity
If transmission schemes with higher effective rates are tried first, then communication efficiency is improved, but reliability decreases when radio conditions change and lower rate schemes are needed
Solution Approach 1:
The patent implements feedback by collecting success/failure information from previous communication trials and using this information to adjust the trial order of transmission schemes. The system continuously learns from past performance and adapts its scheme selection strategy, ensuring both high efficiency and reliability by prioritizing schemes that have proven successful under similar conditions

AI summary
A control method for a communication device including a communication interface for communicating with a wireless terminal includes successively selecting one transmission scheme included in a plurality of transmission schemes according to schedule information and using the selected one transmission scheme for a trial of communications with the wireless terminal via a communication interface in a first period (S201); determining which transmission scheme of the plurality of transmission schemes has succeeded in communicating with the wireless terminal in the first period (S203); and adjusting the schedule information so that a trial of communications using a transmission scheme determined as having succeeded in communicating with the wireless terminal is started earlier in a second period subsequent to the first period than in the first period (S204).
