USER EQUIPMENT OF DEVICE-TO-DEVICE COMMUNICATIONS AND RESOURCE SELECTION METHOD THEREOF

摘要

The invention relates to a user equipment of device-to-device communications and a resource selection method thereof. The user equipment includes a resource selection device and a transceiver device. The resource selection device is configured to create a state machine model, which includes an in-coverage state and an out-of-coverage state corresponding to a base station. The resource selection device is also configured to select a corresponding device-to-device communication resource in response to a current state of the user equipment during transferring of the user equipment from the in-coverage state to the out-of-coverage state or from the out-of-coverage state to the in-coverage state. The transceiver device is configured to perform a device-to-device communication with another user equipment according to the corresponding device-to-device communication resource. The resource selection method includes the steps corresponding to the operations of the user equipment.

主权项

1. A user equipment (UE) of device-to-device (D2D) communications, comprising:
a resource selection device, being configured to create a state machine model that comprises an in-coverage state and an out-of-coverage state corresponding to a base station, and configured to select a corresponding D2D communication resource in response to a current state of the UE during transferring of the UE from the out-of-coverage state to the in-coverage state or from the in-coverage state to the out-of-coverage state; and a transceiver device, being configured to perform a D2D communication with another UE according to the corresponding D2D communication resource.
