SELECTION BETWEEN CELLULAR COMMUNICATION LINK AND DEVICE-TO-DEVICE (D2D) COMMUNICATION LINK FOR COMMUNICATION BETWEEN USER EQUIPMENT (UE) DEVICES

摘要

A transmitting user equipment (UE) device selects between a cellular communication link and a device-to-device (D2D) communication link for transmission for data from the transmitting UE device to a receiving UE device. Based on cellular channel characteristic information and D2D channel characteristic information, the UE device selects between the cellular communication link and the D2D communication link. The cellular channel characteristic information is indicative of at least a portion of a cellular communication link through a base station (eNB) and the D2D channel characteristic information is indicative of the D2D communication link between the transmitting UE device and the receiving UE device.

主权项

1. A method comprising:
obtaining, at a transmitting user equipment (UE) device, cellular channel characteristic information indicative of at least a portion of a cellular communication link through the base station and between the transmitting UE device and a receiving UE device; determining, at the transmitting UE device, device-to-device (D2D) channel characteristic information indicative of a D2D communication link between the transmitting UE device and the receiving UE device; and selecting, at the transmitting UE device, a transmission link from the cellular communication link and the D2D communication link for transmitting data from the transmitting UE device to the receiving UE device, the selecting based at least in part on the cellular channel characteristic information and the D2D channel characteristic information.
