AI Technical Summary

Technical Problem

Existing tagless payment systems for public transportation struggle to accurately distinguish between passenger boarding and alighting times, leading to incorrect payments, especially when the user terminal is near multiple turnstiles.

Method used

Employing ultra-wideband (UWB) communication technology, the access procedure is performed by sending information to the user equipment (UE) including a first hybrid UWB session (HUS) block containing a contention-based ranging block (CBRB), and tagless communication is conducted based on multiple response signals. Precise positioning and payment are achieved using dual-sided bidirectional ranging (DS-TWR) blocks and in-band blocks.

Benefits of technology

It enables accurate identification of passenger location and time in public transportation systems, reducing payment errors and improving the accuracy and efficiency of the payment process.

Abstract

One embodiment of the disclosure relates to an electronic device for performing ultra-wideband (UWB) communication and an operating method thereof. According to one embodiment of the disclosure, a method for performing UWB communication, performed by a first electronic device, can include transmitting, to a terminal, a first ranging measurement message (RMM) including information about a first hybrid UWB session (HUS) block including a contention-based ranging block (CBRB), performing an access procedure with the terminal by receiving, from the terminal in the CBRB, a first response signal including a MAC address, transmitting, to the terminal, a second RMM including information about a second HUS block, receiving, from the terminal, a plurality of second response signals in the second HUS block, and performing a tagless communication with the terminal based on the plurality of second response signals, wherein the second HUS block includes a double-sided two-way ranging (DS-TWR) block and an in-band block.
