User Equipment Relay for Wireless Update Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment outside the coverage area of a wireless access point (AP) cannot obtain timely updates due to limited coverage, and existing solutions that increase signal power lead to communication quality degradation from increased interference.
Innovation Solution
Implement a method where user equipment periodically broadcast beacon messages with information identification, allowing out-of-date devices to establish temporary connections with neighboring devices to receive update information, thereby enabling timely updates without increasing transmit power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If transmit power of wireless AP and user equipment is increased to enlarge signal propagation distance, then coverage area is improved, but signal interference among user equipments increases resulting in communication quality degradation
Solution Approach 1:
The patent introduces intermediate user equipments (relay nodes) that receive information from the wireless AP and forward it to other user equipments. This intermediary mechanism extends coverage without requiring increased transmit power from the AP, thereby avoiding the signal interference and communication quality degradation that would result from power increases.
2Loss of time
If user equipment moves towards wireless AP to obtain update information, then information timeliness is improved, but device mobility and user convenience deteriorate
Solution Approach 1:
The patent enables user equipments to automatically establish temporary connections with neighboring equipments to obtain update information without user intervention or manual movement. The system self-services by autonomously routing information through available relay nodes, maintaining information timeliness while preserving user mobility and convenience.
3Reliability
If temporary connection is established between user equipments for information update, then information transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic temporary connections that are automatically established and torn down based on information update needs. The connection duration and topology are flexible and adaptive, allowing the system to maintain reliability through on-demand connections while minimizing the complexity burden by keeping connections temporary rather than permanent.

AI summary
A method, an apparatus and a system for information transmission are provided. The method includes the following steps. A second user equipment receives update information issued by a wireless access point (AP). The second user equipment is located within a coverage area of the wireless AP. After detecting that the second user equipment has the update information, a first user equipment establishes a connection with the second user equipment and obtains the update information from the second user equipment. A wireless AP of the first user equipment is located outside the coverage area of the wireless AP. In the present invention, the user equipment can update the information without additionally increasing the transmit powers of the wireless AP and the user equipment when located outside the coverage area of the wireless AP, and thus the interference to other equipments is not increased.
