  • Hierarchical frame structure for OFDMA systems with relay
    Patent number: 8204018
    Abstract: An orthogonal frequency division multiple access (OFDMA) frame for transmitting data between a mobile station and a base station includes a downlink subframe including a region for transferring first data to the base station and second data to a relay station at substantially the same time and frequency, and an uplink subframe.
    Type: Grant

  • Method for resource allocation with rectangular bursts
    Patent number: 8130741
    Abstract: A method is provided for allocation downlink bursts in a data region of a OFDMA data system, such data region having along one axis thereof increasing logical sub channel numbers and along another axis thereof increasing OFDMA symbol numbers, and wherein the burst are allocated into rectangular shaped sub regions within the data region. In one embodiment, the method allocates the bursts into rectangular shaped sub regions of the data region with minimum unused sub regions within the data region. In one embodiment, the method creates and locates the data region with minimum unused slots at the lowest logical sub channel number and the lowest OFDMA symbol number. In another embodiment, the method allocates the bursts within a data region having the largest number of OFDMA symbol numbers and then reduces the OFDMA symbol numbers of the data region only when the data region with the smaller OFDMA symbol numbers has less number of unused slots.
