Abstract
A terminal and method of performing device-to-device (D2D) communication by a terminal in a wireless communication system is provided. The method includes determining if a signal including synchronization information is received via at least one of an uplink and a downlink; and when the signal including the synchronization information is not received, transmitting a synchronization information-containing signal.
Claims20
A method by a terminal in a wireless communication system, the method comprising:
- identifying whether first synchronization information is acquired on a downlink;
- identifying, if the first synchronization information is not acquired on the downlink, whether the first synchronization information is acquired on an uplink;
- acquiring, if the first synchronization information is not acquired on either of the uplink or the downlink, second synchronization information by the terminal, the second synchronization information being randomly selected;
- and
- transmitting, if the first synchronization information is not acquired on either of the uplink or the downlink, a signal including the second synchronization information.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver for transmitting and receiving a signal;
- and
- a controller configured to control the transceiver, identify whether first synchronization information is acquired on a downlink, identify, if the first synchronization information is not acquired on the downlink, whether the first synchronization information is acquired on an uplink, acquire, if the first synchronization information is not acquired on either of the uplink or the downlink, second synchronization information by the terminal, the second synchronization information being randomly selected, and transmit, if the first synchronization information is not acquired on either of the uplink or the downlink, a signal including the second synchronization information.
