Title:
A method and a device for determining the distance between devices for device two device communication and proximity service
Document Type and Number:
Japanese Patent JP6203832
Kind Code:
B2
Abstract:
Various systems, methods, apparatuses, and computer-readable media for communicating from device to device are described. Device to Device (D2D) communication may bypass use of a network when devices are in communicable proximity of each other. Knowledge of the relative locations of devices that either are already in D2D mode or are not yet in D2D mode but are capable of using D2D mode may be useful. Therefore, various techniques are described for determining distance between two or more devices. Relative locations may also be used to determine the proximity of two devices for some proximity service of common interest.
