    摘要： Disclosed is a method for performing a network re-entry operation by a target base station (BS). The method includes detecting that a mobile station (MS) is to perform a handover to the target BS; and transmitting to the MS handover process optimization information, included in a Ranging Response (RNG-RSP) message, indicating a possibility of omitting at least one of a process of transmitting a registration response (REG-RSP) message from the target BS to the MS, and a process of transmitting a subscriber station basic capability response (SBC-RSP) message from the target BS to the MS, required by the MS to perform a network re-entry operation with the target BS due to the handover of the MS, wherein if the at least omitted one process is the process of transmitting the REG-RSP message, the handover process optimization information includes information indicating that the target BS omits the process of transmitting the REG-RSP message to the MS, and wherein if the at least one omitted process is the process of transmitting the SBC-RSP message, the handover process optimization information includes information indicating that the target BS omits the process of transmitting the SBC-RSP message to the MS.

    摘要： Provided are an apparatus and method for negotiating a frame offset between a Base Station (BS) and a Relay Station (RS) in a wireless communication system using a multi-hop relay scheme. A communication method of a superordinate station includes, upon detecting an initial access of an relay station, determining an offset value between a frame number used in the superordinate station and a frame number to be used in the relay station; generating a message including RS frame offset information corresponding to the offset value; and transmitting the generated message to the relay station. Accordingly, since the base station and the relay station share the frame offset, the base station can transmit a specific broadcast message in advance to the relay station by considering the frame offset, and the relay station can transmit data, which has to be transmitted in synchronization with the base station at the same time point or at the same frame number, to a Mobile Station (MS) at an exact time point.

    摘要翻译： 本发明提供了在设备和用于协商帧的基站（BS），使用多跳中继方案的无线通信系统中的中继站（RS）之间的偏移的方法。 中的上级站的通信方法包括：当一个中继站的初始接入时，确定检测挖掘到在所述上级站中使用的帧号和帧号之间的偏移值在所述中继站使用; 产生消息包括RS帧偏移信息对应于所述偏移值; 以及发送所生成消息发送到所述中继站。 因此，由于基站和中继站共享帧偏移，基站可以预先向所述中继站通过考虑帧偏移发送特定的广播消息，以及中继站可以发送数据，这必须是在反mitted 与在确切的时间点在相同的时间点或在相同帧号的基站，向移动站（MS）的同步。
