Wireless Data Pre-Processing for 5G MAC PDU Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE systems face limitations in improving data processing speed due to the inability of terminals to perform data pre-processing before receiving uplink transmission resource allocation, which restricts the achievement of high data rates and low latency required for next-generation mobile communication systems.
Innovation Solution
A method and apparatus for a transmitting device that acquires and pre-processes data in multiple layers before receiving resource allocation information, generating a MAC protocol data unit based on pre-processed data and received resource allocation information, enabling efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data pre-processing is performed before resource allocation in LTE systems, then data processing speed increases, but the concatenation function of the RLC layer prevents this operation
Solution Approach 1:
The patent applies preliminary action by performing data pre-processing operations (such as MAC PDU construction, segmentation, and header addition) before the terminal receives uplink resource allocation information from the network. This allows the terminal to prepare data packets in advance, reducing processing latency when resources are allocated and achieving high data rates required for 5G systems.
2Loss of time
If data pre-processing is performed before resource allocation, then latency is reduced, but current LTE architecture does not support this timing
Solution Approach 1:
The patent enables the terminal to perform data pre-processing and generate MAC PDUs before receiving resource allocation information. By preparing data in advance, the terminal reduces processing time and latency when resources are allocated, meeting the low latency requirements of next-generation mobile communication systems.
3Speed
If high data rates up to 20 Gbps are achieved, then next-generation system requirements are met, but current processing architecture cannot support this speed
Solution Approach 1:
The patent implements data pre-processing before resource allocation, allowing the terminal to construct MAC PDUs, perform segmentation, and add headers in advance. This preliminary processing reduces the processing burden during actual transmission and enables the system to achieve high data rates up to 20 Gbps required for 5G communication systems.
