摘要： An apparatus and method for reduces an overhead caused by an operation transition gap in a Relay Station (RS) of a relay wireless communication system. The method includes identifying a signal delay time with an upper node. A transmission/reception operation transition time is determined through a negotiation with the upper node. An idle time is identified. An overhead caused by a transmission/reception operation transition is determined with consideration of a start time point of an Uplink (UL) subframe dependent on the signal delay time, the transmission/reception operation transition time, and the idle time. And communication is performed considering the overhead. The start time point of the UL subframe is set earlier than a start time point of a UL subframe of the upper node in consideration of the idle time.

摘要： An apparatus and method for configuring a Relay-Frame Control Header (R-FCH) transmitted in an intermediary link area in a multi-hop relay Broadband Wireless Access (BWA) communication system are provided. The method includes determining a modulation scheme of a Relay Station (RS) Downlink (DL)-MAP (or simply referred to as R-MAP) in consideration of a channel state with the RS while an initial network entry process is performed by the RS or while communicating with the RS in a Base Station (BS)-RS area where communication is made with RSs connected to the BS and transmitting a message including the determined modulation scheme to the RS. Accordingly, a Modulation and Coding Scheme (MCS) on the R-MAP can be dynamically changed according to a channel state between an RS and a BS, thereby enabling effective use of resources.
