Abstract
A scheduling method and apparatus for a device to device communication are disclosed. The device to device communication method comprises the steps of: transmitting first data to a second terminal through a pre-assigned first sub-frame; and receiving a response corresponding to the first data and second data from the second terminal through a pre-assigned second sub-frame. Therefore, the present invention can prevent a collision of transmitted and received data between the devices.
Claims20
A method, performed by a first terminal, for direct communication between the first terminal and a second terminal, comprising:
- transmitting first data to the second terminal through a previously allocated first subframe;
- and
- receiving a response to the first data and second data from the second terminal through a previously allocated second subframe.
A method, performed by a first terminal, for direct communication between the first terminal and a second terminal, comprising:
- transmitting data to the second terminal through a first subframe which is allocated by a semi-persistent scheduling (SPS) method;
- and
- receiving a response to the data from the second terminal through a previously allocated second subframe.
A method, performed by a first terminal, for direct communication between the first terminal and a second terminal, comprising:
- transmitting a sounding reference signal (SRS) to the second terminal through the last symbol of a previously allocated first subframe;
- and
- transmitting data to the second terminal through a second subframe which is located after the first subframe.
A method, performed by a first terminal, for direct communication between the first terminal and a second terminal, comprising:
- mapping data to a previously allocated first subframe;
- mapping a sounding reference signal to the last symbol of a first subframe;
- and
- transmitting the first subframe to which the data and the sounding reference signal are mapped to the second terminal.
