Base Station Redundancy and Multiplexing for Low Delay Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in achieving both high reliability and low delay, particularly for applications like virtual reality (VR) and augmented reality (AR), where existing methods either increase reliability by repeating data on a time axis but incur significant delay or fail to meet the need for low latency.
Innovation Solution
A communication method and device that generate and transmit redundancy information and multiplexing information to enable repeated transmission of data on a frequency axis, using extended trigger frames to specify redundancy, frequency, and sequence information, allowing data to be transmitted through multiple frequency bands, thereby increasing reliability while reducing delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is repeated on a time axis to increase reliability, then reliability is improved, but delay increases
Solution Approach 1:
The patent transitions from time-axis repetition to frequency-axis repetition. Instead of sending the same data multiple times sequentially in time, the system transmits data across multiple frequency bands simultaneously or in parallel, thereby resolving the contradiction between reliability and delay by changing the dimension of redundancy from temporal to spectral.
2Reliability
If multiple channels are used for simultaneous transmission, then reliability is improved, but system complexity increases
Solution Approach 1:
The base station generates and manages both redundancy information and multiplexing information using a unified control mechanism. The trigger frame structure integrates multiple functions (redundancy specification, frequency allocation, sequence numbering) into a single control message, reducing overall system complexity while enabling multi-channel transmission.

AI summary
The present technology relates to a communication device and a communication method that can achieve communication that has high reliability and low delay. Provided is a communication device that constitutes a base station, the communication device including a control unit that performs a control that generates redundancy information regarding a provision of redundancy for transmission data transmitted by a terminal station or the base station, and multiplexing information regarding multiplexing of the transmission data, and transmits the redundancy information and the multiplexing information that have been generated to the terminal station.
