| 20090154425 | METHODS AND APPARATUS FOR MAKING HANDOFF DECISIONS IN ACCESS TERMINALS CAPABLE OF OPERATING AT DIFFERENT TIMES IN BEST EFFORT AND QoS MODES OF TRAFFIC OPERATION - Methods and apparatus for making handoff decisions in an access terminal which can support both best effort and QoS traffic, e.g., when operating in a best effort and QoS mode of operation, respectively, are described. The access terminal receives an indicator indicating the fraction of communications resources not utilized for QoS service and information indicating a number of best effort users being supported by the attachment point. During QoS mode operation, connections to attachment points which can support the access terminal's minimal QoS requirements are identified and then from among the identified set, the attachment point which can provide a connect supporting the most best effort traffic from the access terminal is selected. In best effort mode operation the access terminal selects the attachment point connection which will provide the greatest amount of throughput to the access terminal for best effort traffic. | 06-18-2009 |

| 20090185475 | NON-ORTHOGONAL SUBCARRIER MAPPING METHOD AND SYSTEM - A method and system of accommodating multiple users through non-orthogonal subcarrier mapping of a single carrier frequency division multiple access system in which input data to a transmitter is modulated via an N-point discrete Fourier transform (N-point DFT), non-orthogonal subcarrier mapping, M-point inverse discrete Fourier transform (M-point IDFT), and cyclic prefix (CP) insertion; the modulated data is transmitted to and received by a receiver; and the received data is demodulated for cyclic prefix (CP) removal, M-point discrete Fourier transform (M-point DFT), subcarrier demapping and equalization, and N-point inverse discrete Fourier transform (N-point IDFT). | 07-23-2009 |

| 20080260054 | METHOD AND APPARATUS FOR REDUCING A PEAK-TO-AVERAGE POWER RATIO IN A MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM - A method and apparatus for reducing a peak-to-average power ratio (PAPR) in a multiple-input multiple-output (MIMO) wireless communication system are disclosed. Transmit beamforming or precoding is performed on transmit symbols based on a channel matrix. For feedback, channel matrices may be averaged over multiple subcarriers and the averaged channel matrices may be further quantized. In order to reduce the PAPR, amplitude clipping may be performed on the symbols after the transmit processing. The amplitude clipping may be performed by hard clipping, soft clipping, or smooth clipping. | 10-23-2008 |

| 20110233487 | Synthesis of Chalcogenide Ternary and Quaternary Nanotubes Through Directed Compositional Alterations of Bacterial As-S Nanotubes - Provided is a method for preparing a chalcogenic hybrid nanostructure including: (a) adding a chalcogenic nanostructure, an electron donor and an electron acceptor to a medium containing metal-reducing bacteria to prepare a reaction mixture, the electron acceptor including a chalcogen element; and (b) performing a metal reduction reaction using the prepared reaction mixture to prepare a chalcogenic hybrid nanostructure with the chalcogen element of the electron acceptor incorporated. The present disclosure provides a new method allowing preparation of a chalcogenic hybrid nanostructure comprising three or more components using metal-reducing bacteria. The disclosure allows preparation of a nanostructure in a more economical and eco-friendly manner. The disclosure also allows control of morphological, physical/chemical and electrical properties of the prepared nanostructure. In addition, the present disclosure provides a nanomaterial that can be useful in nanoelectronic and optoelectronic devices. | 09-29-2011 |
