Random Access via Intermediary Terminal for Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, terminals sensitive to energy consumption face challenges in initiating random access while minimizing energy consumption and maintaining communication performance.
Innovation Solution
A method where a first terminal receives preamble identifier information and random access identifier information from a second terminal, allowing it to obtain random access response information from a network device without sending a random access request, thereby reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal sends a random access request to the network device, then the random access requirement is satisfied, but energy consumption increases
Solution Approach 1:
The patent introduces a second terminal as an intermediary that assists the first terminal in the random access process. The second terminal sends the random access request on behalf of the first terminal, and the first terminal receives the random access response information through the second terminal. This intermediary approach allows the first terminal to satisfy its random access requirement without directly transmitting signals to the network device, thereby reducing its energy consumption.
2Use of energy by moving object
If a terminal uses another terminal to assist in random access, then energy consumption is reduced, but communication complexity increases
Solution Approach 1:
The patent segments the random access process into distinct functional parts: the second terminal handles signal transmission and reception with the network device, while the first terminal handles information processing and response reception. This segmentation allows each terminal to perform specific tasks, reducing the overall complexity for the energy-sensitive first terminal while maintaining complete random access functionality through coordination.

AI summary
A random access method and an apparatus. In the method, random access is completed in a manner in which an agent terminal performs access, so that an access requirement of a terminal can be satisfied under low energy consumption. The method and the apparatus may be applied to application scenarios such as an internet of things (IoT), machine type communication (MTC), massive machine type communication (mMTC), an internet of vehicles, and a connected vehicle.
