Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in improving communication quality and reducing latency and power consumption when transmitting data to multiple terminals without passing through intermediate devices.
Innovation Solution
A communication device with a transfer unit that determines whether data is to be multicast and transmits it directly to other terminals without intermediaries, using modes like intermittent or relay transmission to optimize latency and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted through intermediate communication devices, then transmission reliability is improved, but latency increases
Solution Approach 1:
The patent introduces a determination unit that acts as a smart intermediary to decide whether data should be transmitted directly or through intermediate devices. This intelligent mediation allows the system to bypass intermediate devices when direct transmission is feasible, reducing latency while maintaining reliability through selective use of intermediate devices when needed.
Solution Approach 2:
The system dynamically adjusts the transmission path based on real-time conditions. The determination unit evaluates whether to use direct transmission or relay transmission through intermediate devices, allowing the system to adapt to changing network conditions and optimize the balance between reliability and latency.
2Reliability
If data is transmitted through intermediate communication devices, then transmission reliability is improved, but power consumption increases
Solution Approach 1:
The determination unit serves as an intelligent intermediary that decides when to use intermediate devices for transmission. By selectively enabling intermediate device usage only when necessary for reliability, the system avoids the continuous power consumption that would result from always using intermediate devices, thus optimizing the reliability-power consumption tradeoff.
Solution Approach 2:
The system changes the transmission parameter (direct vs. relay transmission) based on data type and network conditions. This parameter switching allows the system to minimize power consumption by using direct transmission when possible while maintaining reliability through relay transmission when needed.
3Productivity
If multicast transmission is performed without determining data type, then transmission efficiency is improved, but communication quality deteriorates
Solution Approach 1:
The determination unit performs preliminary classification of data types before transmission. By identifying whether data is control data or other data in advance, the system can apply appropriate transmission methods (direct transmission for control data, multicast for other data), ensuring both efficiency and communication quality without requiring complex real-time decisions during transmission.
Solution Approach 2:
The patent applies different transmission qualities to different data types. Control data receives higher quality treatment through direct transmission to ensure reliability, while other data can use efficient multicast transmission. This local quality differentiation optimizes overall system performance by matching transmission methods to data requirements.
Data Source
AI summary
A controller, which is a communication device, includes: a transfer unit including a function of transferring data received from a first terminal to another communication device via wireless communication; and a determination unit configured to determine whether first information is included in the data received by the transfer unit, the first information indicating that the data is to be multicast. The transfer unit is further configured to multicast the data to a second terminal when the determination unit determines that the first information is included in the data, the second terminal and the first terminal being different terminals.
