    • The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-I and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.
    • 本发明提供插入到OFDMA帧中并具有参与传输的所有基站的公共序列的前同步码。 用户站使用公共前导码上的公共序列执行精细同步,并且所得到的峰值将提供候选基站的位置。 然后通过使用基站专用伪噪声序列,在那些峰附近执行基站专用搜索。 通过这两个阶段的单元格搜索,搜索窗口大大减少。 前导码由相应的接收机与已知值匹配以对信号进行解码,并允许多个信号从发射机传送到接收机。 前导码可以包括两个部分,即前导码1和前导码2,其可以在不同的系统中使用,包括多输入多输入(MIMO)系统。

    • A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.
    • 无线通信网络中的移动终端可以是若干操作模式之一。 当处于空闲模式时,如果基站在页面中包括移动终端在响应时可以利用的资源的指示,则移动终端可以避免通常与响应于来自基站的页面相关联的冗长的随机接入过程 这一页。 另外,移动终端可以向基站发送有效的位置更新MAC报头,无论是否由来自基站的页面提示。 此外,在不离开空闲模式或睡眠模式的情况下,移动终端可以与基站交换短数据突发消息。
