METHOD AND APPARATUS FOR SUPPORTING DEVICE TO DEVICE COMMUNICATION SERVICE IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention provides a method and apparatus for supporting device-to-device (D2D) communication in a wireless communication system. The present invention obtains information on time and resources required for signal transmission of corresponding user equipment (UE), estimates transmission time of the signal transmission by using the information on time and resources, and checks propagation delay by comparing the estimated transmission time with reception time of a signal transmitted from an actual corresponding UE. The present invention compares the checked propagation delay with predetermined reference values for converting to D2D communication and determines whether to perform D2D communication. Also, the determining D2D communication may include determining conversion to D2D communication by taking account of a channel state of a received signal.

主权项

1. A method for supporting device-to-device (D2D) communication in a wireless communication system, the method comprising:
receiving a request message, which includes time information and resource information with respect to a signal of a corresponding user equipment (UE), for D2D communication from a network; estimating a channel state with respect to the signal of the corresponding UE by using the time information and the resource information; determining availability of D2D communication by taking account of the channel state; and transmitting a response message which includes indication information on the availability of D2D communication to the network.
