Abstract
An embodiment of the present invention provides a method in which a terminal transmits a device-to-device (D2D) signal in a wireless communication system. The D2D signal transmission method includes: transmitting D2D control information; and transmitting D2D data corresponding to the D2D control information, wherein the D2D control information and the D2D data are transmitted in the same subframe, and the D2D control information and the D2D data are always adjacent to each other in the frequency axis.
Claims10
A method for transmitting a sidelink signal by a UE (user equipment) in a wireless communication system, comprising:
- selecting a plurality of time resources for initial transmission and retransmission for one TB (transport block);
- transmitting a PSCCH (physical sidelink control channel) and a PSSCH (Physical sidelink shared channel) in the plurality of time resources;
- wherein a first PSCCH is transmitted in a first time resource among the plurality of time resources,
- wherein the first PSCCH includes time resource allocation information for the PSSCH transmitted in the first time resource and time resource allocation information for at least one PSSCH retransmitted after the first time resource, and
- wherein a number of PSSCHs and PSCCHs to which time resources are allocated by the first PSCCH is limited within a preconfigured maximum number.
A user equipment for transmitting a sidelink signal in a wireless communication system, comprising:
- a transmitter and a receiver;
- and
- a processor,
- the processor configured to:
- select a plurality of time resources for initial transmission and retransmission for one TB (transport block), and control the transmitter to transmit a PSCCH (physical sidelink control channel) and a PSSCH (Physical sidelink shared channel) in the plurality of time resources,
- wherein a first PSCCH is transmitted in a first time resource among the plurality of time resources,
- wherein the first PSCCH includes time resource allocation information for the PSSCH transmitted in the first time resource and time resource allocation information for at least one PSSCH retransmitted after the first time resource, and
- wherein a number of PSSCHs and PSCCHs to which time resources are allocated by the first PSCCH is limited within a preconfigured maximum number.
