Method for allocating wireless resources in wireless access system and device therefore

摘要

The present invention pertains to a method for allocating wireless resources used in device-to-device communication in a wireless access system which supports device-to-device communication, and a device therefore. Specifically, the invention includes a step for receiving resource control information through a control channel from a base station during device-to-device communication of a first device and a second device, and a step for allocating wireless resources which do not interfere in the device-to-device communication of another device and the second device by using resource control information of the first device when interference with another device occurs due to device-to-device communication of the first device and the second device.

1. A method of allocating a radio resource, which is used for device-to-device (D2D) communication in a wireless access system supportive of the D2D communication, the method, performed in a first device, comprising:
receiving resource control information through a control channel from a base station while the first device performs the D2D communication with a second device; and allocating a radio resource, based on the resource control information, for the D2D communication between the first device and the second device; wherein the allocation of the radio resource does not cause interference with a third device, wherein the resource control information for the D2D communication is transmitted through an e-PDCCH (enhanced Physical Downlink Control Channel), and additional information on the e-PDCCH is transmitted through a legacy PDCCH with a size of one CCE (control channel element), and wherein the resource control information for the D2D communication includes speed information on the second device and moving direction information on the second device.
