  • Method and apparatus for adjusting feedback of a remote unit
    Patent number: 7907960
    Abstract: Methods and apparatus implementing spatial processing in a remote unit. In general, in one aspect, the present invention provides a remote unit, that includes a plurality of antennas and a spatial processing unit coupled to the plurality of antennas. The remote unit also includes a performance determination unit to determine a performance of the remote unit and a feedback adjustment unit to adjust feedback transmitted from the remote unit to a device, wherein the adjusted feedback accounts for performance associated with the spatial processing unit.
    Type: Grant
    Filed: February 24, 2006
    Date of Patent: March 15, 2011
    Assignee: Intel Corporation
    Inventors: Craig H. Barratt, David M. Parish, Stephen J. Sifferman
  • Resource allocation in a circuit switched network
    Patent number: 7554913
    Abstract: Allocating resources in a circuit switched data network, comprising receiving a request for a resource from a device coupled to the circuit switched data network and granting the resource to the requesting device if the resource is available. If the resource is not available, then examining the instantaneous quantity of data to be transmitted by the requesting device; the rate of change in the instantaneous quantity of data to be transmitted by the requesting device; and the time of utilization of the resource by the requesting device, and granting the resource to the requesting device based on the examination of the three factors.
