Document Type and Number:
WIPO Patent Application WO/2015/020431
Kind Code:
A1
Abstract:
A device to device discovery method in a wireless communication system is disclosed. A device determines whether a first subframe for a physical layer uplink channel or a signal is the same as a second subframe for a discovery signal. At this time, when the first subframe and the second subframe are the same, the device transmits, in the same subframe, the physical layer uplink channel or the signal instead of transmitting or receiving the discovery signal.
