  • Patent number: 9706528
    Abstract: Systems, methods, and software can be used to process a control channel at a user agent (UA) within a wireless communication system. In some aspects, the method includes identifying one carrier as an anchor carrier and at least one other carrier as a non-anchor carrier; for each carrier: determining a location of a UA specific search space including one or more control channel candidates for the carrier based on a linear congruential random number; and attempting to decode each of the control channel candidates in the UA specific search space to identify at least one of an uplink or a downlink grant associated with the carrier.

  • Patent number: 9544911
    Abstract: System and method for assigning communications resources in a wireless communications system. A method for operating a base station comprises receiving a resource request for radio resources for a mobile station, in response to a determining that the base station will service the resource request, assigning radio resources based on the resource request and transmitting an indicator of the assigned radio resources to the mobile station, and in response to a determining that the base station will not service the resource request, returning to a normal mode of operations. The assigning of radio requests makes use of a channel tree comprised of two non-orthogonal sets of mappings between nodes of the channel tree and radio resources, with each node corresponding to at least one radio resource.
