| 20100120397 | CREATION AND SIGNALLING OF UE LISTS TO SUPPORT FREQUENCY SELECTIVE REPEATER OPERATION - A method of supporting frequency-selective repeaters (eNodeRs) in a wireless telecommunication system. A base station (eNodeB) classifies User Equipments (UEs) into two categories or lists of users: a white list containing UEs that may need the assistance of repeaters, and a black list containing UEs that do not need repeater assistance. The eNodeB transmits one of these two lists to the eNodeRs. The eNodeRs do not amplify resource blocks (RBs) scheduled for black list UEs. Each repeater may decide on its own whether to amplify signals for a non-black list UE by measuring signals from the UE and comparing them with predefined criteria. | 05-13-2010 |
| 20100238854 | SIGNALING MECHANISMS FOR NETWORK-RELAY INTERFACE WITH REDUCED OVERHEAD - Relay reporting in a wireless network is implemented by efficiently allocating radio resources based on the nature or criticality of the type of relay report. According to an embodiment, a method of communicating with a relay located in a wireless network includes instructing the relay when to transmit reports based on a mapping of different categories of relay reports to one or more different reporting schemes. Reports are received from the relay based on the relay report category and the corresponding reporting scheme. According to another embodiment, a method of reporting information from a relay to a network node of a wireless network includes generating different categories of reports at the relay for transmission to the network node. A reporting scheme associated with each report category is identified and each report is transmitted to the network node in accordance with the reporting scheme identified for the corresponding report category. | 09-23-2010 |

| 20110064006 | FILTER OR AMPLIFIER ADAPTATION BY AN INTERMEDIATE DEVICE IN A MULTI-HOP SYSTEM - A method is performed by an intermediate device in a wireless network. The method includes estimating a first hop channel state based on a transmission originating from a first device. The method further includes estimating an end-to-end signal-to-noise ratio base on a transmission associated with a second device. The method also includes adapting a filter or an amplifier of the intermediate device based on the first hop channel state and the end-to-end signal-to-noise ratio. | 03-17-2011 |
| 20110105170 | Grouping User Terminals into Different Coordination Scheme Groups - In a radio network in which multiple base stations can communicate with multiple user terminals in a coordinated way, user terminals may be grouped into groups, each group representing a coordination scheme to be used for user terminals in the group. The groups may be chosen, for example, according to path loss or QoS requirements Preferably there are three groups requiring no coordination, multiuser coherent coordination and single user coherent coordination respectively. Grouping may be done dynamically according to one or more of the following factors: —the terminal's signalling overhead —the affordable processing complexity —the traffic load —the radio conditions. The grouping unit may be placed in one or more base stations or in any other suitable unit in the network. | 05-05-2011 |
| 20110269395 | Systems and Method for Canceling Feedback Interference - The present application discloses systems and methods for reducing output-to-input feedback signal interference caused by a forwarding node that is configured to forward information received from a transmitter. In some embodiments, this output-to-input feedback signal interference is compensated for by the transmitter. For example, the transmitter is configured such that the signal that is transmitted by transmitter to the forwarding node includes both (1) a primary signal or ‘desired’ signal (e.g., the signal that is intended for a receiving device) and (2) a filtered version of the primary signal. The filter that produces the filtered version of the primary signal is configured (e.g., the filter's filter weights are adapted) such that the filtered version of the primary signal cancels or reduces the undesired output-to-input feedback signal. | 11-03-2011 |

| 20080215717 | Web Based Unified Communication System and Method, and Web Communication Manager - The present invention provides a Web based unified communication system and method, and Web based communication manger. In the present invention, generating a SMIL document, based on a communication request from a terminal, for starting and controlling a communication session between the terminal and corresponding terminals, and controlling the terminals and communication channels involved in the communication session to work collectively so as to perform the communication session by interpreting and executing the SMIL document. In the invention, instead of being a kind of supplementation, the Web technique should become the core technique of such systems. Further, in the invention, terminal may be a set of user devices, the set of user devices includes one or more devices, each of said devices provides media interaction capabilities for one or more communication channels, and each of said devices is mapped to one or more media objects in said SMIL document. Therefore, various devices may work collectively to perform a communication session. | 09-04-2008 |
| 20090129587 | METHOD, SYSTEM AND APPARATUS FOR SHARING MEDIA CONTENT IN A PRIVATE NETWORK - A method, system and apparatus for sharing media content securely and reliably among various computing devices in a private network through media streaming technology is provided. According to the invention, a media streaming apparatus is installed on each computing device, said media streaming apparatus comprises: a controller for controlling a media streaming proxy and a trusted media player to render the requested media stream according to a user's request or the request coming from other application component; the trusted media player for securely rendering the requested media stream for the user under the control of said controller; the media streaming proxy for communicating with the trusted media player the other remote media streaming proxies in said private network, forwarding encrypted media stream, controlling encryption/decryption module to encrypt/decrypt the media player and providing the decrypted media stream to the trusted media player; and the encryption/decryption module for encrypting/decrypting the media stream under the control of the media streaming proxy. | 05-21-2009 |

| 20080222607 | Extending Portability of Java Code Through the Use of AOP - A computer-implementable method, system and computer-usable medium for extending the portability of code to a limited-class environment are disclosed. In a preferred embodiment, the method includes the steps of: identifying any full-version-only objects that are not in a reduced-version of a language, wherein the reduced-version of the language comprises a reduced portion of objects that are in a full-version of the language; associating a full-version-only object with a set of one or more objects in the reduced-version of the language, wherein the full-version-only object is functionally equivalent to the set of one or more objects in the reduced-version of the language; identifying any full-version-only objects in a software program; and creating a reduced-version of the software program by replacing any identified full-version-only objects with a functionally equivalent set of one or more objects from the reduced-version of the language. | 09-11-2008 |
| 20100083266 | METHOD AND APPARATUS FOR ACCESSING A SHARED DATA STRUCTURE IN PARALLEL BY MULTIPLE THREADS - A method of accessing a shared data structure in parallel by multiple threads in a parallel application program is disclosed, in which a lock of the shared data structure is granted to one thread of the multiple threads, an operation of the thread which acquires the lock is performed on the shared data structure, then an operation of each thread of the multiple threads which does not acquire the lock is buffered, and finally the buffered operations are performed on the shared data structure when another thread of the multiple threads subsequently acquires the lock. By using this method, the operations of other threads which do not acquire the lock of the shared data structure can be buffered automatically when the shared data structure is locked by one thread, and all the buffered operations can be performed when another thread acquires the lock. Therefore when the shared data structure is modified, the occurences of an element shift in the shared data structure can be greatly reduced and the access performance of the multiple threads can be improved. A corresponding apparatus and program product are also disclosed. | 04-01-2010 |
