    • A status notification system is implemented on a wireless network. In a standard manner, a network user initiates a communication to a "recipient" unit at the user's "source" wireless unit. If the call is unanswered, information relating to the status of the recipient unit is obtained and transmitted for display on the source unit. The displayed status might be "busy," "in a meeting," or the like, as determined by the system and/or as designated by the user of the recipient unit. The status information may be obtained from the recipient unit, by referencing a database record, or by determining the operational condition of the recipient unit. In another embodiment, when the status of a wireless unit changes, or when the user of the wireless unit changes a designated status, the change in status is transmitted to each wireless unit listed on a "buddy list" for the user.
    • 在无线网络上实现状态通知系统。 以标准方式,网络用户在用户的“源”无线单元发起与“接收者”单元的通信。 如果呼叫没有得到答复,则获得与发送单元的状态相关的信息并发送以在源单元上显示。 所显示的状态可以是由系统确定的和/或由接收者单元的用户指定的“忙碌”,“在会议中”等。 可以通过参考数据库记录,或通过确定接收单元的操作条件,从接收单元获得状态信息。 在另一个实施例中,当无线单元的状态改变时,或者当无线单元的用户改变指定状态时,状态的改变被发送到用户的“好友列表”上列出的每个无线单元。

    • A method is provided for communications in a cellular network (1) comprising a plurality of mobile stations (MS1 to MS3) adapted for performing wireless communications with at least one base station (BS1, BS2) using a first transmission technology, the method comprising: forming a cooperating cluster (C) comprising two or more of the mobile stations (MS1, MS2), and performing short-range communications between the mobile stations (MS1, MS2) of the cooperating cluster (C) using a second transmission technology being different from the first transmission technology for improving, for at least one mobile station (MS1, MS2) of the cluster (C), the performance of the wireless communications with the base station (BS), preferably by using MIMO techniques for at least one of interference suppression and cancellation, in particular by using at least one of transmit pre-coding for uplink transmissions and receive antenna weighting for downlink reception. A mobile station (MS1, MS2) for forming a cooperating cluster (C), a cooperating cluster (C) comprising at least one such mobile station (MS1, MS2), and a cellular network (1 ) are also provided.
    • 提供了一种用于蜂窝网络(1)中的通信的方法,所述蜂窝网络(1)包括适于使用第一传输技术与至少一个基站(BS1,BS2)进行无线通信的多个移动站(MS1至MS3),所述方法包括: 形成包括两个或更多个移动站(MS1,MS2)的协作簇(C),并且使用不同的第二传输技术在协作簇(C)的移动站(MS1,MS2)之间执行短距离通信 从用于改进集群(C)的至少一个移动站(MS1,MS2)的第一传输技术来看,优选地通过使用MIMO技术来执行与基站(BS)的无线通信, 干扰抑制和消除,特别是通过使用用于上行链路传输的发送预编码和用于下行链路接收的接收天线加权中的至少一个。 还提供了用于形成协作簇(C)的移动台(MS1,MS2),包括至少一个这样的移动站(MS1,MS2)和蜂窝网络(1)的协作簇(C)。
