Wireless Data Block Control-Region Payload for Sub-1 ms Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face latency issues in transmitting data, particularly in extreme real-time scenarios, where reducing end-to-end latency beyond 1 ms is necessary to enhance throughput and processing speed.
Innovation Solution
The solution involves allocating payload data to the control region of a data signal block, allowing control and payload data to be transmitted simultaneously, using techniques such as superposition and adaptive modulation, to reduce latency and downlink throughput jitter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If payload data is transmitted only in the payload region of data signal blocks, then control information can be clearly separated and processed, but latency increases to more than 1 ms due to sequential processing requirements
Solution Approach 1:
The patent merges control data and payload data into the same control region of data signal blocks, allowing simultaneous transmission and processing. The receiver processes control data and payload data together in the control region, eliminating the need for sequential processing and reducing latency to less than 1 ms.
Solution Approach 2:
The control region is given multi-functionality by allocating it for both control data transmission and payload data transmission. This allows the control region to serve dual purposes, increasing resource utilization and enabling lower latency transmission without requiring separate dedicated regions.
2Productivity
If the control region is used exclusively for control information, then control data transmission is reliable and simple, but resource utilization is inefficient and throughput is limited
Solution Approach 1:
The control region is designed to handle both control information and payload data, making it a multi-functional resource. This increases throughput by utilizing previously idle control region capacity for data transmission, while the structured allocation method maintains manageable complexity through defined processing procedures.
Solution Approach 2:
The patent adds a new dimension to the control region by superimposing payload data on top of control information in the time-frequency resource grid. This dimensional approach allows simultaneous transmission of both data types without interfering with the fundamental control region structure.
3Loss of time
If control data and payload data are transmitted in separate regions, then processing is straightforward and reliable, but latency cannot be reduced below 1 ms due to processing granularity
Solution Approach 1:
By combining control data and payload data in the control region, the system enables processing at a finer granularity than 1 ms. The receiver processes both data types together in the control region, achieving sub-1 ms latency while maintaining reliability through the structured superposition and processing methods defined in the patent.
Data Source
AI summary
A receiver receives and processes a data signal having at least one data signal block. The data signal block has a number of symbols in the time domain and a number of sub-carriers in the frequency domain. The data signal block includes a control region to provide control data to the receiver and a payload region to provide payload data to the receiver. Payload data is allocated to the control region of the data signal block.
