Random Access Signaling for Early Data Transmission Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in reducing latency times, particularly in situations where terminal devices and base stations are out of synchronization, which hinders efficient data signal transmission.
Innovation Solution
The implementation of a communication system that incorporates a first signal for random access procedures and a second signal for data transmission, allowing for the integration of control information within the second signal to facilitate early data transmission without full random access procedures, thereby reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a communication protocol is designed to be simple and easy to implement, then device complexity and ease of operation are improved, but the ability to handle complex network scenarios and ensure reliable communication deteriorates
Solution Approach 1:
The communication protocol is divided into distinct message types (unicast message, multicast message, broadcast message) with specific formats for each scenario. This segmentation allows the protocol to maintain simplicity for basic operations while providing specialized handling for complex scenarios through structured message fields and dedicated processing logic.
Solution Approach 2:
The protocol dynamically adapts its behavior based on the communication scenario detected through flag fields in the message headers. The system can switch between unicast, multicast, and broadcast modes depending on the network conditions and requirements, allowing simple basic operations while providing dynamic responses to complex scenarios.
2Adaptability or versatility
If a communication protocol includes comprehensive handling for various network scenarios, then communication reliability and adaptability are improved, but protocol complexity and processing overhead increase
Solution Approach 1:
The protocol uses a unified message format that can handle multiple communication scenarios (unicast, multicast, broadcast) through flag fields and parameter combinations. This universal structure allows a single protocol implementation to provide comprehensive network scenario handling without requiring separate complex protocols for each scenario.
Solution Approach 2:
The protocol introduces intermediary flag fields and control parameters that mediate between the simple message structure and the complex network scenarios. These intermediary elements enable comprehensive scenario handling by providing a layered approach where basic message formats are extended through standardized flags and parameters rather than requiring fundamental protocol complexity.
3Ease of manufacture
If the protocol uses standardized message formats for different communication types, then ease of manufacture and implementation are improved, but the flexibility to handle custom communication needs deteriorates
Solution Approach 1:
The protocol provides standardized message formats that cover common communication needs with partial implementation, while including optional fields and configurable parameters that can be enabled or disabled based on specific requirements. This allows easy implementation of standard scenarios while providing excessive capability (optional features) that can be activated when custom communication flexibility is needed.

AI summary
A communication device performs a random access procedure and includes: a transmission unit capable of transmitting a first signal, which is a signal of the random access procedure, and a second signal, which is not a signal of the random access procedure; and a control unit capable of carrying out control in which first information to be transmitted by the first signal is incorporated into the second signal, and control information related to the second signal is transmitted.
