| 20080299917 | CLOSED-LOOP MULTIPLE-INPUT-MULTIPLE-OUTPUT SCHEME FOR WIRELESS COMMUNICATION BASED ON HIERARCHICAL FEEDBACK - The present invention provides methods implemented in a base station having a plurality of antennas and one or more user terminals. One embodiment of the method includes receiving feedback from at least one user in response to transmitting a first frame to said at least one user. The first frame is formed by pre-coding at least one symbol using at least one first code word selected from at least one first code book associated with the at least one user. The method also includes transmitting at least one second frame to the user(s). The second frame(s) are pre-coded using at least one second codeword selected from at least one second codebook. The second codebook(s) determined based on the feedback and the first codeword(s). | 12-04-2008 |
| 20100034151 | METHOD OF JOINT RESOURCE ALLOCATION AND CLUSTERING OF BASE STATIONS - The present invention provides a method for implementation in a first functional entity in a wireless communication system that includes a first plurality of base stations for providing wireless connectivity to at least one mobile unit. In one embodiment of the method includes receiving, at the first functional entity, channel state information associated with a plurality of wireless communication channels between the first plurality of base stations and the mobile unit. Selection of a second plurality of base stations from the first plurality of base stations is performed jointly with resource allocation to the second plurality of base stations using the channel state information. The first functional entity then communicates information indicative of the selected second plurality of base stations and the allocated resources to the selected second plurality of base stations. | 02-11-2010 |

| 20090268657 | Relays in wireless communications - A method is provided, in a wireless communications network comprising a source node, a destination node and at least one relay node, of selecting spatial subchannels for use. The method comprising the steps of: spatially decomposing channels into spatial subchannels; and selecting a subset of the subchannels for use that at least approximately maximises predicted throughput rate. | 10-29-2009 |
| 20120039242 | RELAYING DATA BETWEEN A BASE STATION AND USER EQUIPMENT - A relay operable to relay data between a base station and user equipment of a wireless communications system, a relay-base station pair, methods and computer program products are disclosed. The relay comprises: queuing logic operable, for each user equipment supported by the relay, to form a pending data queue associated with that user equipment, the pending data queue storing received data intended for that user equipment which has yet to be transmitted by the relay over a communications channel between that user equipment and the relay; and scheduling logic operable to schedule transmissions of pending data to each user equipment based on at least one of a size of the pending data queue associated with each user equipment, priority of pending data and channel state information of the communications channel between each user equipment and the relay. In this way, the amount of unnecessary traffic being transmitted between the base station and the relays is reduced, the amount processing resources required in the base station is also reduced and, as a consequence, the deployment of relays within the macro network becomes much more scalable. Accordingly, new relays can be readily deployed where needed without requiring complex and careful network planning. | 02-16-2012 |

| 20090262993 | Pathological tissue mapping - Embodiments of the present invention are directed to quantitative analysis of tissues enabling the measurement of objects and parameters of objects found in images of tissues including perimeter, area, and other metrics of such objects. Measurement results may be input into a relational database where they can be statistically analyzed and compared across studies. The measurement results may be used to create a pathological tissue map of a tissue image, to allow a pathologist to determine a pathological condition of the imaged tissue more quickly. | 10-22-2009 |

| 20110055836 | METHOD AND DEVICE FOR REDUCING POWER CONSUMPTION IN APPLICATION SPECIFIC INSTRUCTION SET PROCESSORS - A method and device for converting first program code into second program code, such that the second program code has an improved execution on a targeted programmable platform, is disclosed. In one aspect, the method includes grouping operations on data for joint execution on a functional unit of the targeted platform, scheduling operations on data in time, and assigning operations to an appropriate functional unit of the targeted platform. Detailed word length information, rather than the typically used approximations like powers of two, may be used in at least one of the grouping, scheduling or assigning operations. | 03-03-2011 |

| 20080296260 | Method For the Fabrication of High Surface Area Ratio and High Aspect Ratio Surfaces on Substrates - This invention provides a method for the fabrication of surfaces of high surface area ratio on polymeric/plastic materials, and their application in the control of the wetting properties of surfaces, of the transport of liquids on such fabricated surfaces, or of the separation of liquids in microchannels of said surfaces. The fabrication of surfaces of high surface area ratio comprises the following steps: (a) selection of a polymer/plastic layer which contains two or more components differing in their plasma etching behaviour (b) exposure of said polymer/plastic layer to an etching plasma to provide selective removal of one polymer component versus a second plasma-resistant component so as to result in a randomly rough columnar-like surface. In addition, exposure of the said surface to an oxidizing plasma or to a fluorocarbon. depositing plasma renders the surface fully hydrophilic or en super-hydrophobic, respectively. | 12-04-2008 |
