DISCOVERY METHOD FOR DEVICE TO DEVICE COMMUNICATION BETWEEN TERMINALS |
| 摘要 |
A discovery method for device to device communication between terminals is disclosed. The discovery method for the device to device communication between terminals comprises the steps of: performing transmission in a first sub-frame; transmitting a discovery channel through a preset section in a second sub-frame located next to the first sub-frame; and performing transmission in a third sub-frame next to the second sub-frame. Therefore, the present invention can transmit and receive the discovery channel without colliding with other data. |

1. An operation method of a user equipment (UE) in a device to device (D2D) communication, the operation method comprising:
generating a discovery channel; and transmitting a D2D subframe including the discovery channel, wherein the D2D subframe includes a plurality of single carrier-frequency division multiple access (SC-FDMA) symbols, a last SC-FDMA symbol among the plurality of SC-FDMA symbols is not transmitted, and a cyclic prefix (CP) for the D2D subframe is independently configured by a high layer signaling. |
