  • Scheduling method in multiple access system and apparatus using the same
    Patent number: 8848698
    Abstract: A method for allocating resources in a wireless communication system is provided. A base station receives a maximum transmission power from a first wireless device. The base station allocates a resource to the first wireless device based on a ratio of the maximum transmission power to a maximum available resource.

  • SCHEDULING METHOD IN MULTIPLE ACCESS SYSTEM AND APPARATUS USING THE SAME
    Publication number: 20130329659
    Abstract: A method for transmitting data streams by a transmitter in a wireless communication system is provided. The transmitter performs Fourier transform for a data stream to generate a transformed stream. The transmitter repeats the transformed stream to generate a repeated stream. The transmitter maps the repeated stream on a plurality of subcarriers to generate a transmission signal. The transmitter transmits the transmission signal to a receiver. The plurality of subcarriers are selected by starting from a subcarrier having a predetermined index and hopping at a subcarrier interval.

  • Method and apparatus of sharing spectrum with legacy communication system
    Patent number: 8145133
    Abstract: A method of sharing spectrum with a legacy communication system includes acquiring spectrum correlation of the legacy communication system, and generating a transmit waveform based on the spectrum correlation. Unlike conventional cognitive radios that utilize spectrum holes only, the proposed method can also utilize spectrally correlated frequency components where primary-user signals are present.
