| 20100153053 | Stream Based Stimulus Definition and Delivery via Interworking - An approach is provided to manage test transactors that interface with components of a hardware design. A first set of transactors is launched with the first set sending stimuli to various components that correspond to the first set of transactors. A manager receives signals when transactors of the first set have completed at which point a second set of transactors is identified that are dependent upon the first set transactors that completed. The second set of transactors is launched by the manager. The manager further facilitates transmission of data used by the various transactors. Transactors generate and provide stimuli to various components included in a hardware design, such as a System-on-a-Chip (SoC). Results from the hardware design are passed to the transactors which, in turn, pass the results back to the manager. In this manner, results from one transactor may be made available as input to another transactor. | 06-17-2010 |
| 20110107146 | Trace Reconstruction for Silicon Validation of Asynchronous Systems-on-Chip - A test system collects passing event data and failing event data, and merges the collected data into passing subsequences and failing subsequences, respectively. The test system identifies an overlap area between the passing subsequence and the failing subsequence in regards to time slices and tracepoint slices, and creates passing transactions and failing transactions using the event data corresponding to the overlap area. Next, the test system detects a timing discrepancy between the first passing transaction relative to the second passing transaction compared with the first failing transaction relative to the second failing transaction. The test system then reports the detected timing discrepancy, which allows a test engineer to perturb the test program in order to more frequently catch intermittent failures caused by asynchronous timing conditions. | 05-05-2011 |

| 20100067604 | NETWORK MULTIPLE ANTENNA TRANSMISSION EMPLOYING AN X2 INTERFACE - A coordinated multipoint transmitter is for use with a multiple antenna super-cell and includes primary and secondary base stations jointly connected via an X2 interface link, wherein the primary base station provides a transmission directive corresponding to an X2 interface protocol over the X2 interface link to the secondary base station for a joint transmission from the primary and secondary base stations. | 03-18-2010 |
| 20100216405 | System and method for interference reduction in self-optimizing networks - A method for interference management in a self optimizing network includes determining quality of service constraints for a call; mapping the quality of service constraints for the call to a target signal-to-interference noise ratio; and transmitting power control signals for the call based on the target signal-to-interference noise ratio. The utility function can be optimized for each class of calls over the network so as to maximize the total number of calls that can be handled. | 08-26-2010 |
| 20100272006 | Design of In-Band Backhaul for Wireless Relays in Wireless Networks - 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. | 10-28-2010 |
| 20100272007 | Protocol Stack and Scheduler for L3 Relay - 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. | 10-28-2010 |
| 20110117967 | INTER-CELL INTERFERENCE COORDINATION - 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. | 05-19-2011 |

| 20090042573 | Radio Bearer Dependent Forwarding For Handover - 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. | 02-12-2009 |

| 20100080137 | Primary and Secondary Associations for Improving Cell Edge Performance in Cellular Networks - 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. | 04-01-2010 |
