    • A system (400), device (500) (401), and method are provided for power saving in a wireless communication network (400), where all devices (401 i ) regularly transmit a beacon (600) but can enter a hibernation mode in which they do not transmit b eacons (600) and operate in a power-saving state. A device (400) announces the start (303) and duration (304) of the hibernation period in its beacon (600) prior to its hibernation period. The neighboring devices (401 i ) keep information on the presence of the beacon (600) of the hibernating device (401) in their own beacons (600) in order to block the beacon slot (204) for the hibernating device (401) during its sleep time. Devices (401 i ) furthermore include an information element (604) in their beacons (600) that contains all receiver addresses for which a device (401 i ) has data pending to be sent.
    • 提供了一种系统(400),设备(500)(401)和方法,用于无线通信网络(400)中的功率节省,其中所有设备(401i)定期地发送信标(600),但是可以进入休眠模式 它们不传输信号(600)并在省电状态下操作。 在其休眠期间之前,设备(400)在其信标(600)中宣布休眠期间的开始(303)和持续时间(304)。 相邻设备(401i)保持关于其自己的信标(600)中的休眠设备(401)的信标(600)的存在的信息,以便在其休眠设备(401)期间阻止休眠设备(401)的信标时隙(204) 睡觉时间。 设备(401i)还包括其信标(600)中的信息元素(604),其包含设备(401i)具有等待发送的数据的所有接收器地址。

    • Each node (42) or station in a wireless ad hoc multi hop network (40) uses an ECC generator polynomial that is probabilistically different from an ECC generator polynomial that is used in a neighboring node (72) when a frame (72 88) is being prepared for transmission. Further more, the data or cargo portion (76) of a data frame that is being prepared for transmission may be shifted by a determined amount prior to an ECC generator polynomial is used generate the ECC for the frame. A field in the data frame, either in the header or footer of the data frame, provides information to the receiving nod (48) about the ECC generator polynomial that was used in the transmitting nod and/or the amount of the data in the cargo portion of data frame is shifted. Although various embodiments of the method and apparatus of the present invention have been illustrated in the accompanying Drawings and described in the foregoing Detailed Description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the invention as set forth herein.
    • 无线自组织多跳网络(40)中的每个节点(42)或台站使用ECC生成多项式,当帧(7288)是(72))时,与其相邻节点(72)中使用的ECC生成多项式概率不同 准备传播。 此外,正在准备传输的数据帧的数据或货物部分(76)可以在使用ECC生成多项式生成用于该帧的ECC之前移位确定的量。 数据帧中的数据帧中的一个字段,在数据帧的头部或页脚中提供关于在发送点和/或货物数据量中使用的ECC生成多项式的接收点(48)的信息 数据帧的一部分被移位。 尽管已经在附图中示出并在前面的具体实施方式中描述了本发明的方法和装置的各种实施例,但是应当理解,本发明不限于所公开的实施例,而是能够进行多种重新布置,修改 和替换,而不脱离本文所阐述的本发明的范围。
