    Abstract: A method of managing a low-duty mode operation is provided by a small base station. The small base station determines a low-duty cycle pattern in which an available interval for data traffic transmission on active air interface and an unavailable interval for transmitting no data traffic are repeated, and provides a terminal with low-duty cycle pattern information. The low-duty cycle pattern information includes a length of the available interval and a start offset indicating a wireless frame at which the low-duty cycle pattern starts.

    Abstract: A method for a first terminal communicating with a base station to perform direct communication with a second terminal is provided. The first terminal determines first timing for transmitting or receiving a first signal to or from the base station. Next, the first terminal determines second timing for transmitting a second signal for terminal discovery to the second terminal. When the first timing and the second timing overlap, the first terminal then changes either the first timing or the second timing.
