摘要： 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.

摘要： The invention discloses a method for use in a wireless communications system with a plurality of broadcasting nodes, comprising the step of enabling one node in the system to function as a central node in said system and letting said node enable measurements on at least one frequency in a frequency band used by the system. Said measurements are carried out to detect if said at least one frequency is being utilized by a transmitter foreign to the system. Preferably, the measurement is enabled by means of the node transmitting a message to other nodes in the system, said message being a message pre-defined within the system as a message prohibiting all nodes from transmitting during a certain interval, said message being transmitted after the system has been detected by the node to be silent during a predefined interval between frame transmissions from the nodes in the system.

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： 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： 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.

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.

The base station is performing multicast transmissions (11, 401) on the physical downlink shared channel (HS-DSCH) by preceding announcement on the shared control channel (HS-SCCH) coded with a multicast identity (MU-ID) of a reserved address space, which downlink shared channel (HS-SCCH) may be decoded simultaneously by a plurality of user entities, wherein each user entity is using the multicast identity (MU-ID) instead of the user entity's respective user identity. A user entity and a method therefore have moreover been provided.
