Abstract
The present invention relates to a method for performing a device-to-device cooperative transmission (D2D CT) using a multi-carrier in a wireless access system, including the steps of: enabling a source device to perform a network entry process with a base station using a primary carrier; enabling the source device to receive control information related to a dedicated carrier used for D2D CT from the base station through the primary carrier; and enabling the source device to transmit an uplink signal to a collaborative device using the dedicated carrier.
Claims18
A method for performing a device-to-device (D2D) communication, the method comprising:
- receiving, by a device, first information on a configuration for the D2D communication from a base station (BS) via a first carrier;
- receiving, from the BS, second information on a power control for a D2D transmission to an adjacent device;
- selecting, by the device, a second carrier, among a plurality of carriers, to be used for the D2D communication with the adjacent device;
- transmitting, by the device and to the BS, third information on the selection of the second carrier;
- and
- performing, by the device, a D2D reception from the adjacent device or the D2D transmission to the adjacent device by using the second carrier,
- wherein both of the D2D reception and the D2D transmission use an uplink resource.
A device for performing a device-to-device (D2D) communication, the device comprising:
- a transceiver;
- a processor configured to control the transceiver thereby performing:
- receiving first information on a configuration for the D2D communication from a base station (BS) via a first carrier;
- receiving, from the BS, second information on a power control for a D2D transmission to an adjacent device;
- selecting a second carrier, among a plurality of carriers, to be used for the D2D communication with the adjacent device;
- transmitting, to the BS, third information on the selection of the second carrier;
- and
- performing a D2D reception from the adjacent device or the D2D transmission to the adjacent device by using the second carrier,
- wherein both of the D2D reception and the D2D transmission use an uplink resource.
