Abstract

The invention relates to a method for configuring D2D (device-to-device) communication with a mode 2, in a first user device of a wireless communication system. The wireless communication system includes a service base station, and at least one D2D user device pair, wherein the at least one D2D user device pair includes a first user device as the transmitting party and a second user device as the receiving party. The method comprises the steps: the first user device receives the first resource pool information for D2D data transmission from the service base station; the first user device intercepts and decodes the scheduling distribution of other D2D user device pairs within the detection range so as to obtain the second resource pool information about a second resource pool; and the first user device selects the resource from the second resource pool indicated by the second resource pool information to perform D2D communication with the second user device. Besides, the invention also relates to a method for configuring D2D communication with a mode 2, in the second user device. The method for configuring device-to-device communication with a mode 2 can reduce and even avoid the interference on D2D communication so as to improve the D2D communication performance.

Description

technical field [0001] The present invention relates to wireless communication technologies, in particular, to a method for configuring Mode 2 device-to-device (D2D) communication in a first user equipment of a wireless communication system and a method for configuring a second user equipment in a wireless communication system. A method for device-to-device (D2D) communication in configuration mode 2 in a user equipment, wherein the first user equipment and the second user equipment serve as the sender and receiver of at least one D2D user equipment pair respectively. Background technique [0002] In today's Mode 2 D2D (Device-to-Device) communication, each D2D transmitter selects resources over itself. If two pairs of D2D user equipments use the same radio frequency resource and the receiver of one pair is close to the transmitter of the other pair, the problem of co-channel interference may occur. [0003] The current solution is that the transmitting user equipment can s...
