Abstract
The present disclosure relates to a method for transmitting and receiving a device-to-device (D2D) signal in a wireless communication system supporting D2D communication, said method, performed by a terminal, comprising the steps of: transmitting a cellular signal on a first subframe of a first component carrier; transmitting a D2D signal on a second subframe of a second component carrier; and when overlapping occurs between the first subframe and the second subframe, dropping the transmission of the D2D signal or reducing transmit power of the D2D signal in a specific interval.
Claims12
A method for transmitting and receiving a device-to-device (D2D) signal by a terminal in a wireless communication system, the method comprising:
- transmitting a cellular signal through a first subframe of a first component carrier;
- transmitting a D2D signal through a second subframe of a second component carrier;
- and
- when overlapping occurs between the first subframe and the second subframe, dropping transmission of the D2D signal in a particular duration or reducing transmission power of the D2D signal.
A method for transmitting and receiving a device-to-device (D2D) signal by a first terminal in a wireless communication system, the method comprising:
- receiving a D2D grant from a base station (BS), the D2D grant including a resource pool used for D2D communication, the resource pool including at least one of a scheduling assignment (SA) resource pool indicating a resource region in which an SA is transmitted and a data resource pool indicating a resource region in which D2D data is transmitted;
- transmitting an SA including information related to D2D data transmission to a second terminal through the SA resource pool;
- and
- transmitting D2D data to the second terminal,
- wherein the D2D grant includes control information related to transmission power control of the SA and/or the D2D data.
A terminal for transmitting and receiving a device-to-device (D2D) signal in a wireless communication system, the terminal comprising:
- a radio frequency (RF) unit transmitting and receiving a wireless signal;
- and
- a processor functionally connected to the RF unit,
- wherein the processor transmits a cellular signal through a first subframe of a first component carrier, transmits a D2D signal through a second subframe of a second component carrier, and performs control to drop transmission of the D2D signal in a particular duration or reduce transmission power of the D2D signal, when overlapping occurs between the first subframe and the second subframe.
