Uplink Data Message Transmission in 5G and 6G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication networks face delays in uplink access due to multiple-step procedures and inefficiencies in transmitting data messages, particularly in managing collisions and decoding destination addresses, which hinder low-latency and high-throughput communication.
Innovation Solution
Implementing pre-grant information uploads, parallel signaling of scheduling requests, early disclosure of destination addresses, and user-specific address databases, along with artificial intelligence to optimize network operations, allowing for reduced delays and improved access efficiency in 5G and future 6G networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple-step access procedure is used in 5G networks, then network control and permission management are improved, but transmission latency increases
Solution Approach 1:
The patent applies preliminary action by having the user equipment transmit scheduling requests and buffer status reports before the actual data transmission. The base station receives and processes these preliminary messages in advance, preparing resource allocation decisions before the data arrives, thereby reducing the latency of the subsequent data transmission step.
Solution Approach 2:
The patent introduces intermediary messages (scheduling requests and buffer status reports) that mediate between the user equipment and the base station. These intermediary messages carry essential information about transmission needs and buffer status, enabling the base station to make informed resource allocation decisions without requiring complex real-time negotiations.
2Loss of information
If destination address is transmitted with data message, then complete information transfer is achieved, but processing time increases
Solution Approach 1:
The patent segments the information transfer into separate components: the data message contains only the payload data, while the destination address is transmitted separately through the scheduling request or buffer status report. This segmentation allows the base station to process routing information independently from the data payload, reducing overall processing time while maintaining information completeness.
3Stability of the object's composition
If traditional uplink access protocol is used, then network stability is maintained, but throughput is limited
Solution Approach 1:
The patent introduces dynamic resource allocation where the base station adjusts transmission parameters based on real-time conditions. The scheduling request mechanism allows flexible timing and resource allocation, enabling the system to adapt to varying network conditions and optimize throughput while maintaining stability through controlled access procedures.

AI summary
Transmission of uplink messages by user devices in 5G and 6G involves substantial delays and numerous complex steps. For lower latency and simpler operation, procedures are disclosed by which a user device can transmit an uplink message in an unscheduled but monitored channel, allocated for at-will transmissions. The user device can transmit a header including, for example, the identity code of the user device, the size of a subsequent data message, and the destination address, followed by the data message. To reduce unnecessary delays, the user device can calculate when the data message is expected to be ready to transmit, and can start transmitting the header at an earlier time, calculated to be finished when the data message will be ready. The data message is then transmitted with zero delay. When low latency is required, the disclosed procedures can reduce delays substantially. Many additional aspects are disclosed.
