Abstract
An embodiment of the present invention provides a method for transmitting device-to-device (D2D) data by a terminal in a wireless communication system, the method for transmitting the D2D data comprising the step of: determining a sub-frame pool for transmitting data, which is configured by only sub-frames capable of transmitting and receiving a D2D signal, among multiple sub-frames; determining a set of subframes to transmit D2D data by applying a time resource patter (TRP) to the sub-frame pool for transmitting the data; and transmitting D2D data in the set of the determined sub-frames.
Claims14
A method of transmitting D2D (device to device) data, which is transmitted by a user equipment in a wireless communication system, comprising:
- determining, by a D2D UE, a subframe pool for transmission of the D2D data including only subframes capable of transmitting and receiving a D2D signal among a plurality of subframes including D2D available subframes and D2D unavailable subframes;
- determining, by a D2D UE, a set of subframes in which the D2D data is to be transmitted from the subframe pool for the transmission of the D2D data based on a subframe indicator bitmap,
- wherein the subframe indicator bitmap is repeatedly used for the determined set of the subframes;
- and
- transmitting the D2D data in the determined set of the subframes.
A user equipment transmitting a D2D (device to device) signal in a wireless communication system, comprising:
- a reception module;
- and
- a processor configured to determine a subframe pool for transmission of D2D data including only subframes capable of transmitting and receiving the D2D signal among a plurality of subframes including D2D available subframes and D2D unavailable subframes, the processor configured to determine a set of subframes in which the D2D data is to be transmitted from the subframe pool for the transmission of the D2D data based on a subframe indicator bitmap,
- wherein the subframe indicator bitmap is repeatedly used for the determined set of the subframes, and
- the processor is further configured to transmit the D2D data based on the set of the subframes.
