Solution Overview
Problem
In wireless communication systems, base stations and terminals lack the ability to acquire relative geographical location information, hindering optimization techniques such as beam forming and user scheduling.
Innovation Solution
A communication device that determines a reference geographical location and generates relative location information, transmitting it to communication objects via the air interface to minimize overhead, allowing for improved wireless network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relative geographical location information is transmitted via air interface, then wireless network performance is improved, but communication overhead increases
Solution Approach 1:
The patent applies local quality by transmitting only the necessary relative location information (delta coordinates) rather than complete absolute location data. This selective transmission of locally relevant information reduces overhead while maintaining the performance benefits needed for beam forming and user scheduling.
Solution Approach 2:
The location information is segmented into reference location data and relative offset data. By dividing the complete location information into these components, the system transmits only the variable relative portion over the air interface, reducing overhead while enabling performance optimization through accurate relative positioning.
2Measurement precision
If complete absolute location information is transmitted, then location accuracy is improved, but communication efficiency deteriorates
Solution Approach 1:
The patent extracts only the essential relative location offset information from the complete absolute location data. By taking out and transmitting only the delta coordinates needed for relative positioning, the system maintains location accuracy for network optimization while improving communication efficiency through reduced data transmission.
3Quantity of substance
If no location information is transmitted, then communication overhead is reduced, but beam forming and user scheduling optimization are hindered
Solution Approach 1:
The patent applies partial action by transmitting only the minimum necessary location information (relative offsets) rather than complete location data. This partial transmission is sufficient to enable beam forming and user scheduling optimization while keeping communication overhead low, avoiding the excess of transmitting full absolute coordinates.
