  • Patent number: 9179385
    Abstract: 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.

  • Patent number: 8649364
    Abstract: A method and system of accommodating different mapping schemes in a transmission using an orthogonal direct sequence spread spectrum technique in which input data to a transmitter is spread by conversion into a sequence of complex numbers modulated for N-point discrete Fourier transform (N-point DFT), subcarrier mapping, M-point inverse discrete Fourier transform (M-point IDFT), and cyclic prefix (CP) insertion; the spread and modulated data is transmitted to and received by a receiver; and the received data is despread 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).

  • Patent number: 8285283
    Abstract: Method and apparatus for an access terminal which makes handoff decisions between a number of potential alternative attachment points based on service level indicating metrics are described. The access terminal computes a service level indicating metric differently for a current connection than for a potential alternative connection. A service level indicating metric is a function of loading information and received signal strength. A selection may be made by selecting between attachment points by selecting the attachment point having the highest service level indicating metric from among a plurality of attachment points, one per possible carrier where the attachment point which is considered for a given carrier is the one having the best connection for the given carrier. The access terminal handoff decision approach provides handoff decisions which are nearly as optimal as those which can be achieved using a centralized control node but without the requirement for centralized handoff decisions.

  • Publication number: 20090185475
    Abstract: 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).

  • Publication number: 20080260054
    Abstract: 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.
