摘要： In a wireline or wireless telecommunications system or data network, which employs a Selective Repeat Automatic Repeat Request (ARQ) to convey data packet reception status for a sequence of data packets grouped together into a number of blocks of data packets, partial bit mapping is employed to improve efficiency, particularly with respect to bandwidth. This may be accomplished, more specifically, by including in the ARQ message that is sent from the receiver to the sender, a number of partial bitmaps, along with a corresponding number of bitmap block numbers, where a first bitmap block number identifies a particular one of the blocks of data packets and the corresponding bitmap defines the reception status of the data packets in that block. Each of the remaining bitmap block numbers identify an additional block of data packets relative to the first block of data packets. Accordingly, the remaining bitmap block numbers require fewer bits to identify their corresponding data packet blocks.
摘要翻译：在有线或无线电信系统或数据网络中，其使用选择性重复自动重传请求（ARQ）来将分组在一起的数据分组序列的数据分组接收状态传送到多个数据分组块，采用部分比特映射以提高效率，特别是在带宽方面。这可以更具体地通过将从接收器发送到发送器的ARQ消息中包括多个部分位图以及相应数量的位图块号码来实现，其中第一位图块号码标识特定的一个的数据分组块和相应的位图定义了该块中的数据分组的接收状态。剩余的位图块号码中的每一个标识相对于第一数据包块的附加数据包块。因此，剩余的位图块号需要较少的比特来标识它们对应的数据分组块。

摘要： In accordance with embodiments of the invention, in a Wireless Local Area Network (WLAN) configured in accordance with the HIPERLAN Type 2 standard where an Access Point (AP) and Mobile Terminals (MTs) use a duplex airlink having a MAC frame structure to communicate with each other, when an MT fails to properly perceive and decode a wakeup announcement in the MAC frame that is directed to it by the AP, the MT will remain awake and continue to decode and monitor subsequent MAC frames until it either receives a wakeup announcement directed to it, or until a predetermined number of MAC frames transpire. Where the MT fails to correctly decode a wakeup announcement and/or fails to send an acknowledgment signal back to the AP when the wakeup announcement includes a polling request, the AP will continue to resend the wakeup announcement and any appropriate, associated downlink data pending for the AP, in subsequent MAC frames. The AP continues until either the MT correctly receives the wakeup announcement and responds appropriately, or until a predetermined number of MAC frames expire.
摘要翻译：根据本发明的实施例，在根据HIPERLAN类型2标准配置的无线局域网（WLAN）中，其中接入点（AP）和移动终端（MT）使用具有MAC帧结构的双工空中链路进行通信相互之间，当MT无法正确地感知和解码由AP指向的MAC帧中的唤醒通知时，MT将保持唤醒，并继续解码并监视后续MAC帧，直到它接收到唤醒通知或者直到预定数量的MAC帧发生。当唤醒通知包括轮询请求时，MT无法正确解码唤醒通知和/或无法将确认信号发送回AP，则AP将继续重新发送唤醒通知和任何适当的相关联的下行链路数据待处理 AP，在随后的MAC帧中。 AP继续直到MT正确地接收到唤醒通知并且适当地响应，或直到预定数量的MAC帧过期。

摘要： In a WLAN where an AP and MTs use a duplex airlink having a MAC frame structure to communicate with each other, the AP places wakeup PDUs at different locations in a MAC frame to allow the MTs to conserve energy by maximizing sleep time. In other embodiments, the wakeup PDUs are sequenced by MAC-ID so that a MT can conclusively determine whether remaining wakeup PDUs in a sequence can contain its MAC-ID, and go to sleep early if they cannot. In another embodiment, a wakeup PDU type can indicate to a corresponding MT whether the MT can expect downlink data later in the same MAC frame. In addition, the wakeup PDU type can indicate to the MT that the MAC frame that it should awaken and remain awake to receive downlink data in the future.
摘要翻译：在AP和MT使用具有MAC帧结构的双工空中链路相互通信的WLAN中，AP在MAC帧中的不同位置放置唤醒PDU，以允许MT通过最大化睡眠时间来节省能量。在其他实施例中，唤醒PDU通过MAC-ID进行排序，使得MT可以最终确定序列中的剩余的唤醒PDU是否可以包含其MAC-ID，并且如果它们不能早早睡觉。在另一个实施例中，唤醒PDU类型可以向相应的MT指示MT是否可以在同一MAC帧中稍后期望下行链路数据。此外，唤醒PDU类型可以向MT指示其应该唤醒并保持唤醒的MAC帧以在将来接收下行链路数据。

摘要： A wireless local area network (LAN) is operated so that a mobile terminal (MT) transmits various power-related information over an air interface to a power status repository (PSR) of the wireless local area network (LAN). For example, in one aspect of the invention, the mobile terminal transmits power status information, the power status information having an indication of whether the mobile terminal is currently operating using battery power or line power. The power status information is transmitted at one of the following times: (1) upon power-up of the mobile terminal; (2) upon command issued from the power status repository; (3) upon establishment of a connection between the mobile terminal and the LAN; and (4) upon a change in power status for the mobile terminal. The power status repository (PSR) can take the form of an Access Point (AP) for an intranet, or another mobile terminal in the case of an ad hoc network. In differing embodiments, the power status information can either be transmitted as a dedicated message or in a message with other status information. In another aspect, the mobile terminal which transmits to the power status repository certain measurement capability information. The measurement capability information has an indication of whether the mobile terminal has a capacity to perform radio frequency measurements. For example, the measurement capability information can indicate one of low power of the mobile terminal or a power restriction on the mobile terminal. As another example, the measurement capability information can indicate a particular sleep mode of the mobile terminal. In accordance with yet another aspect of the invention, if the power status repository does not have sufficient measurements regarding radio frequency (in view, e.g., of power incapacitation by one or more mobile terminals (MTs) in its cell), the power status repository can modify (e.g., increase) a rate at which a frequency measurement command is transmitted to other mobile terminal(s) in the cell. In still another aspect of the invention, the mobile terminal determines a duration of a sleep cycle in accordance with the power status information of the mobile terminal.

摘要： Embodiments of the present invention include a method and system for operating a dual mode terminal that includes a wireless local area network interface and a cellular radio interface. According to an embodiment, the dual mode terminal camps on the cellular radio interface when idle. When a Page Request message is received over the cellular radio interface, the terminal determines whether wireless local area network coverage is possible from an access point providing wireless local area network cellular communication. If so, the terminal processes the incoming communication request over the wireless local area network towards another party, wherein then the communication is ended, the terminal goes back to camp on the cellular channel.
