Angle Measurement Capability Negotiation for Accurate Device Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing angle measuring methods in communication devices often fail due to mismatched angle measuring capabilities between transmitter and receiver devices, leading to inaccurate distance and positioning measurements.
Innovation Solution
A method and apparatus for communication devices to negotiate and determine their respective roles as transmitting or receiving sides for angle of arrival (AOA) or angle of departure (AOD) measurements by exchanging angle measuring capability information, ensuring compatible antenna configurations for accurate angle calculations.

Engineering Contradiction Analysis
1Measurement precision
If angle measuring methods are implemented in communication devices, then positioning accuracy is improved, but device compatibility fails due to mismatched angle measuring capabilities between transmitter and receiver
Solution Approach 1:
The patent applies preliminary action by introducing a capability negotiation phase before actual angle measurement. The transmitter and receiver exchange capability information messages to determine compatible measurement methods in advance, ensuring that both devices agree on the angle measuring approach before execution, thereby preventing compatibility failures while maintaining positioning accuracy
Solution Approach 2:
The patent employs parameter changes by dynamically selecting different angle measuring parameters (AOA, AOD, or both) based on the negotiated capabilities of the devices. The system adjusts the measurement parameters according to what each device supports, allowing flexible adaptation to different device configurations while achieving accurate positioning
2Adaptability or versatility
If angle measuring capability negotiation is implemented, then device compatibility is improved, but communication overhead increases due to additional message exchanges
Solution Approach 1:
The patent applies universality by designing capability information messages that serve multiple functions: they not only convey angle measuring capabilities but also establish the basis for subsequent measurement operations. This multi-functional approach reduces the need for separate negotiation and measurement setup messages, thereby minimizing communication overhead while ensuring device compatibility
