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： A system and method for coordinating interference in cellular systems are disclosed herein. In one embodiment, a cellular base station interference coordinator includes an interference estimator. The interference estimator estimates a level of interference caused by transmissions controlled by a host base station for each of a plurality of radio resources, and provides interference estimates corresponding to the radio resources to a target base station. Each interference estimate is based on transmit power and channel strength to the target base station for each transmission controlled by the host base station for a radio resource.

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： 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 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.
