Abstract: In a method for transmitting data from a first node to a second node through first and second relay units in a wireless communication system: a) a first symbol is transmitted from the first node to the second node and the first relay unit during a first time slot section; b) the first symbol, which is received from the first node, is transmitted from the first relay unit to the second node during a second time slot section; c) a second symbol is transmitted from the first node to the second node and the second relay unit during the second time slot section; and d) the second symbol, which is received from the first node, is transmitted from the second relay unit to the second node during a third time slot section.

Abstract: Provided are a channel switching method for effectively performing channel switching in a cognitive radio system while protecting an incumbent user, a method of managing a frequency channel, and a base station and customer premises equipment (CPE) using the methods. In the channel switching method performed by the base station, a currently unavailable first frequency channel is detected from among at least one uplink/downlink frequency channel which is set as a communication channel with the CPE; a channel switching request message requesting switching from the first frequency channel to a second frequency channel is transmitted to the CPE; and the first frequency channel is switched to the second frequency channel when a channel switching report message reporting that channel switching is to be performed in response to the channel switching request message is received from the CPE.
