Information Block Sub-Block Splitting for 5G Uplink Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in 5G New Radio (NR) scenarios, the grant-free access scheme leads to inaccurate determination of uplink resources based on signal-to-interference-plus-noise ratio (SINR), resulting in suboptimal channel transmission quality due to mismatch with current wireless network conditions.
Innovation Solution
A method where user equipment splits information blocks into sub-blocks based on indication information from the base station, allowing for adaptive transmission to match different wireless network channel conditions, and processes these sub-blocks for improved transmission quality.

Engineering Contradiction Analysis
1Speed
If grant-free access scheme is used to reduce delay and increase connected devices, then access speed and device capacity are improved, but channel transmission quality deteriorates due to inaccurate SINR-based resource determination
Solution Approach 1:
The information block is segmented into multiple sub-blocks with different sizes. Each sub-block can be independently processed and transmitted, allowing the system to adapt to different channel conditions without requiring accurate SINR-based resource allocation, thus maintaining both fast access and reliable transmission.
Solution Approach 2:
The patent changes the transmission parameter by using indication information to specify sub-block sizes rather than relying on SINR-based resource determination. This parameter change enables the system to operate effectively in grant-free access mode while maintaining transmission quality.
2Productivity
If scheduling/authorization-based uplink access is used to achieve high throughput and good channel match, then transmission efficiency is improved, but access delay increases and device connection speed decreases
Solution Approach 1:
By segmenting the information block into sub-blocks, the patent enables a hybrid approach where devices can quickly access the network with grant-free transmission while the sub-block structure allows for efficient resource utilization, thus reducing access delay without significantly compromising throughput.
Solution Approach 2:
The base station preliminarily determines sub-block sizes and provides indication information to the device before transmission. This preliminary action enables the device to immediately transmit using the indicated sub-block configuration without waiting for SINR-based scheduling, thus reducing access delay while maintaining transmission efficiency.
