Method for transceiving signal in wireless communication system and apparatus therefor
Disclosed is a method for transceiving D2D data in a wireless communication system supporting device-to-device (D2D) communication, the method carried out by a first terminal comprising the step of transceiving a signal with a second terminal by means of a frame comprising one or more from among a first subframe to which a resource associated with D2D communication is allocated or a second subframe to which a resource associated with cellular communication is allocated, wherein if an overlap occurs between the first subframes or between the first subframe and the second subframe, then the signal transmission/reception from the overlapped section or a subframe comprising the overlapped section is dropped.
1. A terminal for transmitting a device-to-device (D2D) signal using a first component carrier and a cellular signal using a second component carrier in a wireless communication system supporting a carrier aggregation, the terminal comprising:
a radio frequency (RF) unit including a transceiver and configured to transmit and receive a wireless signal; and
a processor functionally connected to the RF unit, wherein the processor
controls the RF unit to transmit the D2D signal on the first component carrier to a second terminal;
controls the RF unit to transmit the cellular signal on the second component carrier to a base station; and
punctures on an overlapped portion of the first component carrier based on timing advance (TA) to control a transmission power of the D2D signal not to exceed a maximum transmission power in the overlapped portion of a subframe if the transmission of the D2D signal overlaps with the transmission of the cellular signal.
2. A method for transmitting, by a first terminal, a device-to-device (D2D) signal using a first component carrier and a cellular signal using a second component carrier in a wireless communication system, the method comprising:
transmitting the D2D signal on the first component carrier to a second terminal;
transmitting the cellular signal on the second component carrier to a base station; and
puncturing on an overlapped portion of the first component carrier based on timing advance (TA) to control a transmission power of the D2D signal not to exceed a maximum transmission power in the overlapped portion of a subframe if the transmission of the D2D signal overlaps with the transmission of the cellular signal.
3. The method of claim 2 , wherein the D2D signal is transmitted in a first subframe, and the cellular signal is transmitted in a second subframe.
4. The method of claim 3 , wherein the first subframe is a subframe #n, and the second subframe is a subframe #n+1.
5. The method of claim 2 , wherein the overlapped portion is less than 100% of the first subframe.
