Abstract
The present specification relates to a method for transmitting and receiving data in a wireless communication system supporting device-to-device (D2D) communication, and the method performed by a first terminal comprises the steps of: acquiring a resource pool used for D2D communication, wherein the resource pool includes either a scheduling assignment (SA) resource pool indicating a resource region through which an SA is transmitted or a data resource pool indicating a resource region through which D2D data is transmitted; transmitting, to a second terminal through the SA resource pool, the SA including information related to D2D data transmission; and transmitting the D2D data to the second terminal.
Claims10
A method for transmitting, by a first terminal, device-to-device (D2D) data in a wireless communication system, the method comprising:
- receiving, from a base station, a resource pool used in a D2D communication via a higher layer signaling,
- wherein the resource pool includes first resource information related to a first control information transmission and second resource information related to a D2D data transmission;
- receiving, from the base station, a first downlink control information (DCI) format defined for the D2D communication;
- generating the first control information based on the received first DCI format;
- transmitting, to a second terminal, the generated first control information,
- wherein the generated first control information includes information related to the D2D data transmission;
- and
- transmitting the D2D data to the second terminal,
- wherein the first DCI format is CRC (Cyclic Redundancy Check) scrambled by a specific RNTI (Radio Network Temporary Identifier),
- wherein the specific RNTI is a D2D RNTI, and
- wherein at least one padding bit is appended until a size of the first DCI format is equal to a size of a second DCI format.
A first terminal for transmitting device-to-device (D2D) data in a wireless communication system, the first terminal comprising:
- a radio frequency (RF) unit for transmitting and receiving a wireless signal;
- and
- a processor functionally connected to the RF unit,
- wherein the processor is configured to:
- receive, from a base station, a resource pool used in a D2D communication via a higher layer signaling,
- wherein the resource pool includes first resource information related to a first control information transmission and second resource information related to a D2D data transmission;
- receive, from the base station, a first downlink control information (DCI) format defined for the D2D communication;
- generate the first control information based on the received first DCI format;
- transmit, to a second terminal, the generated first control information,
- wherein the generated first control information includes information related to the D2D data transmission;
- and
- transmit the D2D data to the second terminal,
- wherein the first DCI format is CRC (Cyclic Redundancy Check) scrambled by a specific RNTI (Radio Network Temporary Identifier),
- wherein the specific RNTI is a D2D RNTI, and
- wherein at least one padding bit is appended until the size of the first DCI format is equal to the size of a second DCI format.
