    • A method of operating a base station and an apparatus for transmitting multicast data in a broadband wireless communication system are provided. The method includes receiving multicast data including a multicast Internet Protocol (IP) address from a source terminal, the multicast IP address being an address used in a network layer, and transmitting the multicast data to at least one terminal by including the multicast IP address to a control message of a Media Access Control (MAC) layer. The sending of the MAC layer control message including the multicast IP address includes, when a corresponding terminal is in an idle mode, sending a paging message including at least part of the multicast IP address, after sending the paging message, sending a resource allocation MAP message for multicast transmission including at least part of the multicast IP address, and transmitting the multicast data based on the resource allocation MAP message.
    • 提供一种在宽带无线通信系统中操作基站的方法和用于发送组播数据的装置。 该方法包括从源终端接收包括组播互联网协议(IP)地址的组播数据,所述组播IP地址是网络层中使用的地址,并且通过将所述组播IP地址包括到所述至少一个终端来发送所述多播数据 媒体访问控制(MAC)层的控制消息。 包括组播IP地址的MAC层控制消息的发送包括当相应的终端处于空闲模式时,在发送寻呼消息之后发送包括多播IP地址的至少一部分的寻呼消息,发送资源分配MAP 用于组播传输的消息,包括至少部分组播IP地址,以及基于资源分配MAP消息来发送组播数据。

    • An apparatus and method for Automatic Repeat reQuest (ARQ) feedback polling in a wireless communication system are provided. The method for ARQ feedback polling includes transmitting at least one ARQ block to a receive end, polling ARQ feedback to the receive end using an extended header, determining if ARQ feedback information is received from the receive end within a lifetime of ARQ feedback, determining success or failure of transmission of the at least one ARQ block through the ARQ feedback information if it is determined that the ARQ feedback information is received within the lifetime of ARQ feedback, and polling ARQ feedback again to the receive end if it is determined that the ARQ feedback information is not received within the lifetime of ARQ feedback.
    • 提供了一种用于无线通信系统中的自动重复请求(ARQ)反馈轮询的装置和方法。 用于ARQ反馈轮询的方法包括将至少一个ARQ块发送到接收端,使用扩展报头向接收端轮询ARQ反馈,确定在ARQ反馈的生命周期内是否从接收端接收到ARQ反馈信息,确定成功 如果确定在ARQ反馈的生命周期内接收到ARQ反馈信息,并且如果确定ARQ反馈再次向接收端轮询ARQ反馈,则通过ARQ反馈信息来传输至少一个ARQ块的失败; 在ARQ反馈的生命周期内没有收到反馈信息。

    • A method and a system for providing a push service in a wireless communication system adopting an Orthogonal Frequency Division Multiplexing (OFDM) scheme or an Orthogonal Frequency Division Multiple Access (OFDMA) scheme are provided. The method includes when receiving a message from another network or another messaging server, transmitting, at a messaging server, a push service request message to a push server; when a Mobile Station (MS) of which the push service is requested using the push service request message of the messaging server, operates in an awake mode, transmitting, at the push server, a first push deliver message comprising a message designated for the MS, to a Base Station (BS), and when receiving the first push deliver message, transmitting, at the BS, a second push deliver message based on a Media Access Control (MAC) layer comprising the message designated for the MS, to the MS.
    • 提供了一种在采用正交频分复用(OFDM)方案或正交频分多址(OFDMA)方案的无线通信系统中提供推送服务的方法和系统。 该方法包括当从另一网络或另一个消息收发服务器接收到消息时,在消息收发服务器处向推送服务器发送推送服务请求消息; 当使用消息传送服务器的推送服务请求消息请求推送服务的移动台(MS)以唤醒模式操作时,在推送服务器处发送包括指定给MS的消息的第一推送传递消息 并且当接收到第一推送传递消息时,在BS处,基于包括为MS指定的消息的媒体访问控制(MAC)层向MS发送第二推送传送消息 。
