    • An apparatus and a method for resource allocation in a multi-hop relay BWA(Broadband Wireless Access) communication system are provided to allocate resources dynamically according to a frame structure for supporting multiple frequency bandwidths and the traffic load of each link, thereby supporting a relay service using the multiple frequency bandwidths and solving the efficiency deterioration of resources caused by the unbalance of load by each link. An i-numbered frame(300) is divided into a downlink sub frame(310) and an uplink sub frame(320) as time resources. The downlink sub frame and the uplink sub frame are divided into a first section(311,321) and a second section(313,323) by using the time resources. A TTG(Transmit/Receive Transition Gap)(331) of a time protection area exists between the downlink sub frame and the uplink sub frame. An RTG(Receive/Transmit Transition Gap)(333) of a time protection area exists between the i-numbered frame and an (i+1)-numbered frame. A BS(Base Station)(350) transmits a preamble, control information and a downlink burst successively to a terminal 1 connected by a link during the first section of the downlink sub frame. The BS transmits control information, a downlink burst, and a post amble to an RS(Relay Station)(360) successively during the second section. The control information included in the second section includes the resource allocation information of the control information about the resource allocation information of a control information area which the RS transmits to the terminal 1. The BS receives an uplink burst from the terminal 1 during the first section of the uplink sub frame. The BS receives the uplink burst from the RS during the second section. The RS transmits a preamble, control information, and a downlink burst successively to a terminal 2 connected by a relay link during the first section of the downlink sub frame. The RS receives control information, a downlink burst, and a post preamble from the BS during the second section successively. The RS receives the uplink burst from the terminal 2 during the first section of the uplink sub frame. The RS transmits the uplink burst received from the terminal 2 during the first section to the BS during the second section. An R-TTG(Relay TTG)(335) of a time protection area exists between the first section and second section of the downlink sub frame. An R-RTG(Relay RTG)(337) of a time protection area exists between the first section and second section of the uplink sub frame.
    • 提供了一种用于多跳中继BWA(宽带无线接入)通信系统中的资源分配的装置和方法,用于根据用于支持多个频带宽度的帧结构和每个链路的业务负载动态分配资源,从而支持中继 服务使用多频带宽,解决每个链路负载不平衡引起的资源效率恶化。 i编号帧(300)作为时间资源被划分为下行链路子帧(310)和上行链路子帧(320)。 下行链路子帧和上行链路子帧通过使用时间资源被划分为第一部分(311,321)和第二部分(313,323)。 在下行链路子帧和上行链路子帧之间存在时间保护区域的TTG(发送/接收转换间隙)(331)。 时间保护区域的RTG(接收/发送转换间隙)(333)存在于i编号的帧和第(i + 1)个数量的帧之间。 BS(基站)(350)在下行链路子帧的第一部分期间,连续发送前导码,控制信息和下行链路突发信号到由链路连接的终端1。 在第二部分期间,BS连续向RS(中继站)(360)发送控制信息,下行链路突发和后导码。 包括在第二部分中的控制信息包括关于RS向终端1发送的控制信息区域的资源分配信息的控制信息的资源分配信息.BSB在第一部分期间从终端1接收上行链路突发 的上行链路子帧。 BS在第二部分期间从RS接收上行链路突发。 RS在下行链路子帧的第一部分期间连续发送前导码,控制信息和下行链路突发信号到由中继链路连接的终端2。 RS在第二段期间从BS接收控制信息,下行链路突发和后置前导码。 在上行链路子帧的第一部分期间,RS从终端2接收上行链路突发。 在第二部分期间,RS在第一部分期间将从终端2接收的上行链路突发发送到BS。 在下行链路子帧的第一部分和第二部分之间存在时间保护区域的R-TTG(中继TTG)(335)。 在上行链路子帧的第一部分和第二部分之间存在时间保护区域的R-RTG(中继RTG)(337)。
