摘要： This invention extends the coverage and improves the capacity of wireless communication networks using relay nodes. The relay nodes are wirelessly connected to the base station. The base station uses the same radio access technology for a link between the base station and user equipment and between the base station and the relay node. The relay node uses the same radio access technology for a link between the base station and the relay node and between the relay node and the user equipment. The relay node supports at least a Physical Layer (PHY), a Medium Access Control (MAC) sub-layer and a Radio Link Control (RLC) sub-layer protocol.

摘要： This invention is a method for extending the coverage and/or improving the capacity of wireless communication networks comprising inserting a Relay Node (RN) in the Radio Access Network (RAN). The relay node relays the signal between the Base Station node (eNB) and the User Equipment (UE). The relay node is wirelessly connected to the base station. The base station uses the same radio access technology (RAT) for the base station to user equipment link and the base station to relay node link. The relay node uses the same radio access technology for the base station to relay node link and the relay node to user equipment link. The relay node is non-transparent and seen as base station by the user equipment.

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： Systems and Methods for task allocation in a multiprocessor environment employing power management techniques are described wherein tasks are allocated relative to the density given by the ratio of worst-case-execution time and deadline of a task and also the harmonicity of a task's period with respect to a task-set. Tasks are allocated to a given processor based on either minimum density or maximum harmonicity depending on which allocation results in a lower clock frequency. Assigning a task to the processor with lowest density results in balancing the density across processors while assigning task to the processor with maximum harmonicity attempts to maximize the utilization of the processor.

摘要： The duration of receiver on-times may be minimized by sensing and reacting to communication channel power levels at intervals. When no energy is detected on the communication channel, then the receiver may be turned off for a channel sampling interval. If energy is detected on the channel, then the receiver may remain on to determine if a received message is associated with the device. Receiver on-time may also be minimized by adjusting the timing of messages used for broadcast messages sent by routing or other protocols. Broadcast messages, such as network routing topology messages, may be controlled in two phases. In a first phase, the broadcast messages are sent with at a high rate to allow nodes to join the network rapidly. In a second phase, the broadcast messages are sent with at a lower rate to minimize interference with data and other messages in the network.
摘要翻译：接收器接通时间的持续时间可以通过以间隔感测和响应通信信道功率电平来最小化。当在通信信道上没有检测到能量时，接收机可以被关闭以用于信道采样间隔。如果在信道上检测到能量，则接收机可以保持接通，以确定接收到的消息是否与设备相关联。通过调整用于由路由或其他协议发送的广播消息的消息的定时，接收器接通时间也可以被最小化。诸如网络路由拓扑消息之类的广播消息可以分两个阶段进行控制。在第一阶段，以高速发送广播消息，以允许节点快速加入网络。在第二阶段中，以较低的速率发送广播消息以最小化对网络中的数据和其他消息的干扰。

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。

摘要： A method for performing packet lookups is provided. Packets (which each have a body and a header) are received and parsed to parsing headers. A hash function is applied to each header, and each hashed header is compared with a plurality of binary rules stored within a primary table, where each binary rule is a binary version of at least one ternary rule from a first set of ternary rules. For each match failure with the plurality of rules, a secondary table is searched using the header associated with each match failure, where the secondary table includes a second set of ternary rules.
摘要翻译：提供了一种用于执行分组查找的方法。数据包（每个都有一个主体和一个头）被接收并解析为解析头。将哈希函数应用于每个头部，并且将每个散列头部与存储在主表中的多个二进制规则进行比较，其中每个二进制规则是来自第一组三元规则的至少一个三元规则的二进制版本。对于与多个规则的每个匹配失败，使用与每个匹配失败相关联的标题来搜索次表，其中次表包括第二组三进制规则。
