Wireless Relay Control for High-Frequency Dead Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless relay devices, such as reflectors and smart repeaters, lack control mechanisms to enable or disable radio signal relay between a base station and a terminal effectively, particularly in high-frequency bands where dead zones are common due to strong rectilinearity of radio waves.
Innovation Solution
A wireless relay device equipped with a communication unit to receive control information from a base station, a control unit to manage relay functions based on this information, and a relay unit to transmit and receive signals accordingly, enabling or disabling the relay of radio signals based on the control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless relay device is deployed to relay radio signals in high-frequency bands, then communication quality can be improved by covering dead zones, but the device lacks effective control mechanisms to enable or disable relay functions dynamically
Solution Approach 1:
The patent implements a feedback mechanism where the wireless relay device receives control information from the base station through signaling, allowing the relay device to dynamically adjust its relay function based on network conditions and commands, thus resolving the lack of control capability while maintaining communication quality improvement
Solution Approach 2:
The patent enables the relay device to transition between relay and non-relay states dynamically based on control information received from the base station, allowing flexible adaptation to different communication scenarios and network conditions in high-frequency bands
2Area of stationary object
If relay function is continuously enabled to cover dead zones, then communication coverage is improved, but energy consumption increases and network interference may increase
Solution Approach 1:
The patent enables periodic or conditional activation of the relay function based on control information from the base station, allowing the relay device to operate only when needed for coverage enhancement rather than continuously, thus reducing energy consumption while maintaining coverage where required
Solution Approach 2:
The patent allows selective relay activation in specific areas or time periods based on network conditions, enabling the relay function to be applied locally rather than universally, which reduces overall energy consumption while maintaining coverage in dead zones where it is most needed

AI summary
A wireless relay device includes: a communication unit that receives signaling including control information related to a relay function from a base station; a control unit that controls the relay function based on the control information; and a relay unit that executes the relay function of receiving a first signal from the base station, transmitting the first signal to a terminal, receiving a second signal from the terminal, and transmitting the second signal to the base station, in which the control unit enables or disables transmission and reception of the first signal and transmission and reception of the second signal based on the control information.
