    摘要： Disclosed is a method for recognizing by a Mobile Subscriber Station (MSS) whether a serving Base Station (BS) retains connection information in a mobile communication system including the serving BS for providing a service to the MSS and a target BS adjacent to the serving BS. The method includes the steps of receiving a handover request message from the serving BS, the handover request message including a resource remain type field representing whether the connection information having been set with the serving BS is retained, and a resource retain time field representing a connection information-retaining time by the serving BS, and recognizing that the serving BS retains the connection information during a time determined by a value of the resource retain time field.

    摘要： A method for determining a number of ranging slots by a base station (BS) in a broadband wireless access (BWA) communication system. The method includes counting the number of mobile stations (MSs) that succeeded in ranging in a current frame, determining a ranging slot occupation ratio in the current frame, comparing a ranging slot occupation ratio of a previous frame with the ranging slot occupation ratio of the current frame, detecting an increase in the number of ranging-requesting MSs, if the ranging slot occupation ratio of the current frame is greater than the ranging slot occupation ratio of the previous frame, and determining the number of ranging slots of a next frame such that the number of ranging slots of the next frame is greater than the number of ranging slots of the current frame.

    摘要： An apparatus and a method for sending a control message for retransmission in a multihop relay wireless communication system are provided. Data received from a lower node is checked for errors. The data is transmitted to an upper node, when the data has no errors. When two or more messages, which include at least one of Acknowledgement (ACK) messages and Negative ACK (NACK) messages in response to a data reception are received from one or more lower nodes, the two or more messages are transmitted to the upper node at the same time. Accordingly, the RS can transmit the control messages for the ARQ provided from the lower nodes, to the upper node at the same time.
