Solution Overview

Problem

Current wireless communication systems face challenges in handling high-frequency data signaling, particularly at frequencies above 52.6 GHz, due to increased data rates and processing speed requirements, which are not adequately addressed by existing technologies, leading to issues with code block size and signaling overhead.

Innovation Solution

The implementation of a method and device for wireless communication networks that utilize a code block size and length based on indications from control information messages, allowing for efficient data signaling with reduced overhead by mapping code blocks to integer numbers of allocation units and using modulation and coding schemes to optimize data transmission.

Core Design Contradiction:

ProductivityVSSpeed

Solution Approach 1:

The patent segments the data transmission into code blocks that can be independently processed. By dividing the overall data stream into smaller code blocks, the system can process multiple blocks in parallel, thereby increasing processing speed and reducing latency while maintaining the high data rates enabled by higher frequencies

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary actions by pre-configuring code block sizes and processing parameters before actual data transmission. This allows the system to be prepared for high-speed processing in advance, reducing the latency that would otherwise occur during dynamic parameter adjustment at transmission time

Solution Approach 1:

The patent dynamically changes the code block size parameter based on the specific transmission conditions, data size, and frequency band being used. This allows optimization of processing latency by using smaller blocks when needed, while avoiding excessive signaling overhead by adapting the block size to match the actual requirements of each transmission scenario
