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.
Claims15
A method of transmitting, by a first terminal, device-to-device (D2D) data in a wireless communication system the method comprising:
- receiving, from a base station, information for resource pool used in a D2D communication via a higher layer signaling,
- wherein the information for the resource pool includes first resource information related to control information transmission and second resource information related to a D2D data transmission;
- receiving, from the base station, a first downlink control information (DCI) related to the D2D communication;
- generating the control information based on the first DCI;
- transmitting, to a second terminal, the control information,
- wherein the control information includes information related to the D2D data transmission;
- and
- transmitting the D2D data to the second terminal,
- wherein at least one padding bit is appended until a size of a second DCI related to a communication with the base station is equal to a size of the first DCI.
A first terminal for transmitting device-to-device (D2D) data in a wireless communication system, the first terminal comprising:
- at least one transceiver for transmitting and receiving a wireless signal;
- and
- at least one processor functionally connected to the at least one transceiver,
- wherein the at least one processor is configured to:
- receive, from a base station, information for resource pool used in a D2D communication via a higher layer signaling,
- wherein the information for the resource pool includes first resource information related to a control information transmission and second resource information related to a D2D data transmission;
- receive, from the base station, a first downlink control information (DCI) related to the D2D communication;
- generate the control information based on the first DCI;
- transmit, to a second terminal, the control information,
- wherein the control information includes information related to the D2D data transmission;
- and
- transmit the D2D data to the second terminal,
- wherein at least one padding bit is appended until the size of a second DCI related to a communication with the base station is equal to the size of the first DCI.
