Patents by Inventor Mark Andrew Earnshaw

Mark Andrew Earnshaw has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Uplink control channel resource mapping in carrier aggregation systems
    Patent number: 9007963
    Abstract: Certain aspects of the present disclosure describe determining a downlink (DL) hybrid automatic repeat request (HARD) timing linkage between a first component carrier and a second component carrier, the first component carrier having a different uplink (UL) and DL configuration than the second component carrier. A derived downlink association set can be determined. A PUCCH resource in a subframe can be identified based on a first downlink association set associated with the first component carrier and the derived downlink association set.
    Type: Grant

  • Uplink control channel resource collision resolution in carrier aggregation systems
    Patent number: 8923196
    Abstract: Systems, methods, and apparatuses of a wireless communications network include identifying a resource collision between uplink channels for acknowledgement/negative acknowledgement (ACK/NACK) signaling of a first component carrier and a second component carrier. An indicator representative of the ACK/NACK signaling of the first component carrier and the second component carrier can be identified.

  • Uplink control channel resource collision avoidance in carrier aggregation systems
    Patent number: 8923255
    Abstract: Systems, apparatuses, and methods of a wireless communications network include identifying a first downlink control channel. The possibility of an acknowledgement/negative acknowledgement (ACK/NACK) resource collision on a first uplink control channel is determined for a first component carrier and a second uplink control channel for a second carrier component. A second downlink control channel can be identified to avoid the ACK/NACK resource collision.

  • EXPLICIT INDICATION OF UPLINK CONTROL CHANNEL RESOURCES IN CARRIER AGGREGATION SYSTEMS
    Publication number: 20130242881
    Abstract: Systems, apparatuses, and methods performed as part of a wireless communications network include determining a downlink (DL) hybrid automatic repeat request (HARQ) timing for a first component carrier and a second component carrier, the first component carrier having a different DL HARQ timing configuration than the second component carrier. A physical uplink control channel (PUCCH) resource can be identified for the second component carrier. An indicator of the PUCCH resource can be sent to a user equipment.
