ABSTRACT:
An apparatus and method of controlling an action change gap interval in a multi-hop relay cellular network, includes constructing a first symbol included in a first frame as a first interval for a first action change and a second interval for exchanging data; and constructing a last symbol included in the first frame as a first interval for exchanging data and a second interval for a second action change. Accordingly, the system capacity and the system efficiency can be raised by reducing the overhead due to the action change gap in the cellular network.
