Detection Assistance Apparatus for WiGig Access Point Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
WiGig communication systems face challenges in discovering access points with small coverage areas due to limited signal range, leading to increased search loads for radio terminals.
Innovation Solution
A communication system that includes a radio base station, an access point, and a detection assistance apparatus, where the radio terminal detects a signal broadcast from the detection assistance apparatus to initiate a discovery procedure for the access point, allowing for channel information exchange to facilitate connection to the access point with a smaller coverage area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a radio terminal performs discovery procedure by directly detecting access point signals, then the discovery can be initiated, but the search load increases and discovery efficiency decreases due to small coverage area
Solution Approach 1:
A detection assistance apparatus is introduced as an intermediary between the radio terminal and the access point. The detection assistance apparatus broadcasts a detection signal that helps the radio terminal locate the access point more efficiently. This mediator resolves the contradiction by providing an intermediate detection layer that reduces the direct search burden on the terminal while maintaining discovery capability.
Solution Approach 2:
The detection assistance apparatus performs preliminary detection actions by broadcasting detection signals before the actual discovery procedure. This preliminary action prepares the radio terminal by providing initial location information, thereby reducing the subsequent search load and improving overall discovery efficiency.
2Speed
If the access point uses a small coverage area for WiGig service, then high-speed data communication is achieved, but the discovery range is limited
Solution Approach 1:
The system adds a spatial dimension to the coverage structure by introducing a detection assistance apparatus with a larger coverage area that encompasses or overlaps with the access point's smaller coverage area. This dimensional expansion allows terminals outside the immediate access point range to detect and initiate connection procedures, effectively extending the discovery range without compromising the high-speed communication capability within the core coverage area.

AI summary
A communication system 1 comprises: a radio base station 100 having a first coverage area 100 A; an access point 200 having a second coverage area 200 A; and a detection assistance apparatus 300 having a third coverage area 300 A. A radio terminal 100 existing in the radio base station 100 starts a discovery procedure for the access point 200, after detecting a detection-use signal broadcast from the detection assistance apparatus 300.
