摘要： A frame configuration method and apparatus for sending data via an RS in a broadband wireless communication system are provided. In the reception mode, the RS monitors reception of data in an (n−1)th frame from an MS and reception of data in an nth frame from a BS. The RS classifies the data received from the MS and the data received from the BS as combinable data to be sent in combination or as non-combinable data to be sent separately, and stores the classified data distinguishably. When the RS transitions to a transmission mode, it determines whether to XOR-operate or mask the stored data. If the stored data can be masked, the RS XOR-operates the stored data and sends the masked data to the BS and the MS.
摘要翻译：提供一种用于在宽带无线通信系统中通过RS发送数据的帧配置方法和装置。在接收模式中，RS监视从MS接收第（n-1）帧中的数据，并从BS接收第n帧中的数据。 RS将从MS接收到的数据和从BS接收到的数据作为可组合数据组合或作为不可组合数据单独发送，并且可区分地存储分类数据。当RS转换到传输模式时，它确定是否异或操作或掩蔽存储的数据。如果存储的数据可以被屏蔽，则RS XOR操作存储的数据，并将掩蔽的数据发送到BS和MS。

摘要： A method and an apparatus for controlling call admission in an OFDM mobile communication system are provided. Upon receipt of a call admission request, it is determined whether a requested call is a handoff call or a new call and the traffic service type and QoS level of the requested call are determined. The amount of resources required for the call is calculated using the QoS level and the amount of resources of on-going calls is calculated according to the traffic service type. The amount of available resources in a cell is calculated using the amount of resources of the on-going calls and it is determined whether to admit the call by comparing the available resource amount with the required resource amount.

摘要： A frame communication apparatus and method for a broadband wireless communication system are provided that employ a transmitter. In the transmitter, a control channel generating unit generates burst allocation information including a receiver identification (ID) with respect to a transmission packet, a burst generating unit constructs data burst by adding a header including a traffic ID to the transmission packet, and a transmitting unit transmits the burst allocation information and the data burst. An existing connection ID (CID) is subdivided into a user ID (UID) and a traffic ID (TID). The UID and the TID are recorded in a map channel message and a medium access control (MAC) header, respectively. Accordingly, an amount of information contained in a downlink map (DL-MAP) and uplink map (UL-MAP), and an amount of the MAC header of a data packet can be reduced.

摘要： Provided are an apparatus and a method for providing a concurrent data service to an Mobile Station (MS) through a plurality of heterogeneous networks. In a method for providing a data service to an MS through different wireless networks, the MS measures channel qualities of at least one accessible wireless network and reports the measured channel qualities to an Internet Protocol (IP) packet controller. The IP packet controller selects wireless networks for data transmission on the basis of the reported channel qualities, distributes data destined for the MS, and transmits the distributed data to the selected wireless networks. The selected wireless networks receive the data from the IP packet controller and transmits the received data to the MS. The MS combines and interprets the data received from the selected wireless networks. Accordingly, it is possible to provide a seamless data service to the MS in service environments with a mixture of different wireless communication systems.

摘要： Provided is an apparatus and method for communicating a frame in a multi-hop relay cellular communication system. When communicating at a Relay Station (RS), a Downlink (DL) signal is received from a Base Station (BS) and the received DL signal is reconfigured during a first section of a frame. The reconfigured DL signal is transmitted to a Mobile Station (MS) during a second section of the frame. During a third section of the frame, a UL signal is received from the MS and is reconfigured. The reconfigured UL signal is transmitted to the BS during a fourth section of the frame. The RS recovers data from the BS to retransmit only specific data corresponding to the BS. Accordingly, unnecessary retransmission can be prevented and thus resources can be used efficiently.
摘要翻译：提供了一种用于在多跳中继蜂窝通信系统中传送帧的装置和方法。当在中继站（RS）进行通信时，从基站（BS）接收下行链路（DL）信号，并且在帧的第一部分期间重新配置所接收的DL信号。在帧的第二部分期间，重新配置的DL信号被发送到移动台（MS）。在帧的第三部分期间，从MS接收UL信号并被重新配置。在帧的第四部分期间，将重新配置的UL信号发送到BS。 RS从BS恢复数据，只重发与BS相对应的特定数据。因此，可以防止不必要的重传，从而可以有效地使用资源。
