    • 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.

    • 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.
    • 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。

    • A central controller (CC) [22] of a wireless Local area network (LAN) [20], in conjunction with an association operation with a mobile terminal [24] and upon receiving from the mobile terminal (MT) a first control signal [CS1] of a sequence of control signals involved in the association operation, pre-reserves a MAC resource for transmission of at least a further control signal in the sequence. The MAC resource for the further control signal is pre-reserved prior to information for the further control signal being stored in a transmission buffer [58] of the mobile terminal. In essence, judging from the nature of the first control signal, the central controller (CC) anticipates eventuality of the further control signal and pre-reserves the MAC resource for the further control signal. The central controller (CC) pre-reserves the MAC resource to avoid transmission of a separate message to request a MAC resource for the further control signal. The association operation for which the pre-reservation occurs can be, for example, an initial association scenario or a handover scenario in which the mobile terminal (MT) is handed over to the central controller (CC).
    • 无线局域网(LAN)[20]的中央控制器(CC)[22]结合与移动终端[24]的关联操作,并且在从移动终端(MT)接收到第一控制信号[ CS1]在预定的MAC资源中预先规定至少一个控制信号的序列。 用于进一步控制信号的MAC资源在用于进一步控制信号的信息被存储在移动终端的传输缓冲器[58]之前被预先保留。 实质上,从第一控制信号的性质来看,中央控制器(CC)预测进一步的控制信号的可能性,并为另外的控制信号预先预留MAC资源。 中央控制器(CC)预先预留MAC资源以避免发送单独的消息以请求用于另外的控制信号的MAC资源。 发生预先预约的关联操作可以是例如移动终端(MT)切换到中央控制器(CC)的初始关联场景或切换场景。

    • 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.
    • 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。

    • In a packet transmission system, especially wireless transmission system, where data is transmitted in packets at different error protection levels and where the error protection level of one packet (=the succeeding packet) may differ from the error protection level of a preceding packet without providing code termination between the said preceding and the said succeeding packet the performance may degrade in case a different error protection level is used by the preceding packet and the succeeding packet. The invention proposes in these cases to insert a supplementary packet between the preceding and the succeeding packet whereby the error protection level of the supplementary packet is higher than the lowest error protection level that is used either by the preceding or the succeeding packet.

    • A method for a first base station (BS1) and a base station are provided being adapted to receive uplink transmissions at transmission opportunities from a given user entity (UE). The method comprises the steps of detecting whether the following conditions I-III are all found to exist I—whether a transmission from a given user entity is received on a transmission opportunity (10, 20), II—whether an overload situation exists in the base station, III—whether the base station is in a state of soft handover with regard to receiving an expected transmission from the given user entity, and if conditions 1-111 are all found to exist, at least refraining (24) from issuing a power down (DOWN) signal, wherein the refraining (24) from issuing a power down signal (DOWN) is performed although the signal to interference (SIR) level may be above a predefined first level nor-mally giving rise to issuing a power down (DOWN) signal.
