摘要： A digital communications system for delivering data blocks includes at least one transmit/receive unit (TRU). The TRU includes a storage element for receiving transmit data packets and retransmit data packets from a sending unit and a processing element communicatively coupled to the storage element. The processing element is configured for recognizing a failure to receive at least one other transmit data packet (missing data packet) from the sending unit, and for configuring a status control packet for transmission to the sending unit, the control packet includes a header including a next packet identifier for a next data packet anticipated to be received and a status payload portion including a missing packet identifier including the transmit packet identifier for the missing data packet. In the system, the retransmit data packet includes at least a segment of the data payload in the missing data packet associated with the missing packet identifier.

摘要： Systems and methods for reduction of handover latencies in wireless communication systems are described herein. Some illustrative embodiments include a wireless mobile communication device that includes a wireless transceiver including a transmitter configured to transmit a first signal synchronized for reception by a first cellular node, and processing logic that couples to the wireless transceiver. Before the wireless transceiver receives a handover command the processing logic causes the transmitter to transmit a second signal for reception by a second cellular node to request allocation of an upload resource for communication with the second cellular node as part of an impending handover.

摘要： Embodiments of the invention provide a method to efficiently enable Network MIMO for use in the downlink direction. An association is established between a primary NodeB in a first cell and a secondary NodeB in an adjacent second cell. A set of downlink transmission resources is reserved for use by both the primary NodeB and the secondary NodeB. A transport block is transmitted from the secondary NodeB simultaneously with the primary NodeB to a user equipment (UE) near the edge of the first cell in response to a schedule provided by the primary NodeB. A time instance of the reserved transmission resources is released by the secondary NodeB when no simultaneous transmission of a transport block is scheduled within a minimum time.

摘要： A device comprising transceiver logic and control logic coupled to the transceiver logic. The control logic is adapted to use the transceiver logic to broadcast a signal comprising either a Request-to-Send (RTS) signal or a Clear-to-Send-to-Self (CTS2S) signal to a plurality of other devices. The signal is adapted to cause the plurality of other devices to refrain from transmitting data. After at least some of the plurality of other devices have received the signal, the transceiver logic transmits at least part of another signal using beamforming techniques.

摘要： A novel and useful synchronization mechanism that functions to provide a uniform time base for mesh points in a WLAN mesh based network. The invention enables timing synchronization to a common reference clock base by advertising the common TSF within beacon transmissions. All MPs in a mesh share a common DTIM interval. The synchronization mechanism enables the mesh points to avoid collisions in the generation and transmission of beacons. The TBTT offsets of the current MP and its neighbors are advertised in beacons so that neighboring MPs that hear the beacons can select non-overlapping TBTT offsets. Each MP receives one or more beacons from its neighbors and compares the timing of its neighbors to that of itself and adopts the highest TSF (i.e. the fastest) in the mesh. Eventually, all MPs in the mesh will adjust their timing to that of the MP with the fastest clock. The reception of beacons by MPs from its neighbors is also advertised. This allows for MPs to verify that the beacons they send are actually heard and are not in collision with beacon transmissions of other MPs.
摘要翻译：一种新颖有用的同步机制，用于为基于WLAN网络的网络中的网点提供统一的时基。本发明通过在信标传输中通告公用TSF来实现与公共参考时基的定时同步。网格中的所有MP共享一个常见的DTIM间隔。同步机制使网格点能够避免信标的生成和传输中的冲突。当前MP及其邻居的TBTT偏移在信标中公布，使得听到信标的相邻MP可以选择不重叠的TBTT偏移。每个MP从其邻居接收一个或多个信标，并将其邻居的定时与其本身的定时进行比较，并采用网格中最高的TSF（即最快）。最终，网格中的所有MP将以最快的时钟调整MP的时间。接收来自其邻居的议员的信标也被广告。这允许MP验证其发送的信标实际上被听到并且不与其他MP的信标传输相冲突。

摘要： This invention employs an inherent tradeoff in a radio bearer dependent data handling method for intra-E-UTRA handoffs. For user equipment using real time data, the source node forwards to the target node not yet acknowledged real time service data units and disconnects. This makes the handoff latency short at the expense of data traffic between nodes. For user equipment not needing real time data, the source node continues to receive user equipment acknowledgements during a time out period and only forwards service data units acknowledged during the time out period. This reduces X2 interface traffic between the source and target nodes but extends the handoff latency.
摘要翻译：本发明在用于E-UTRA切换的无线载体相关数据处理方法中采用固有的权衡。对于使用实时数据的用户设备，源节点向目标节点转发尚未确认的实时业务数据单元和断开连接。这使得切换延迟短于节点之间的数据流量。对于不需要实时数据的用户设备，源节点在超时期间继续接收用户设备确认，只转发在超时期间确认的业务数据单元。这减少了源节点和目标节点之间的X2接口流量，但是扩展了切换延迟。
