AI Technical Summary
Technical Problem
In UWB communication, communication interruptions can occur due to equipment failure or radio interference, and existing methods to mitigate radio interference are insufficient in resolving communication failures caused by equipment malfunctions.
Method used
A communication method involving a master unit and multiple slave units using different preamble codes, where the master unit checks the communication status of non-communicating slave units with another slave unit to differentiate between radio interference and equipment malfunctions.
Benefits of technology
Enables accurate estimation of the cause of communication interruptions, distinguishing between radio interference and equipment failure, thereby improving communication stability in UWB systems.

Abstract
This technology provides the ability to estimate the cause of communication interruptions in UWB communication. [Solution] An exemplary communication method is a communication method between a master unit and multiple slave units using UWB communication, wherein the master unit communicates with the multiple slave units using multiple different preamble codes, the multiple slave units communicate with each other using preamble codes different from the multiple preamble codes, and when the master unit detects a slave unit among the multiple slave units that it cannot communicate with, it checks the communication status of the other slave unit with the slave unit that cannot communicate.
