  • Patent number: 9332512
    Abstract: At least one of transmissions and receptions over allocated radio resources within a first timing advance group are synchronized using a first timer; and similar for allocated radio resources within a second timing advance group that are synchronized using a second timer. In response to determining that the first timer remains synchronized while the second timer is not synchronized with a radio network which has allocated the respective radio resources, a first procedure is followed for the case in which there is a primary component carrier within the second timing advance group and a different second procedure for the case in which there is no primary component carrier within the second timing advance group. In an exemplary embodiment, a message is sent to the radio network indicating that the second timer has expired. Various distinctions between the two procedures, and how the message is sent, are detailed for different embodiments.

  • Patent number: 9094905
    Abstract: A method, apparatus and computer program product are provided to facilitate the determination of the timing advances of each of a plurality of component carriers by triggering the determination of the timing advances in response to certain pre-defined events that are indicative of a need for the timing advance to be determined. A method may include determining that a pre-defined event has occurred and triggering a determination of a timing advance for a second component carrier relative to a timing advance of a first component carrier based upon occurrence of the predefined event. In this regard, both the component carriers are concurrently allocated to a mobile terminal. The method may also utilize the timing advance to synchronize communications on the second component carrier between the mobile terminal and a network. A corresponding apparatus and computer program product may also be provided.

  • Patent number: 8948319
    Abstract: A technique includes jointly demodulating a desired signal and an interfering signal of a received signal in response to a carrier-to-interference ratio estimate for the received signal being below a threshold level. The jointly demodulating is based on first channel impulse response coefficients associated with the desired signal and second channel impulse response coefficients associated with the interfering signal. The technique includes determining the first channel impulse response coefficients based on a first cross-correlation function between the received signal and a training sequence of the desired signal and determining the second channel impulse response coefficients based on a second cross-correlation function between the received signal and a training sequence of the interfering signal.

  • Patent number: 8903775
    Abstract: Provided are a method, system, and program for using a heartbeat signal to maintain data consistency for writes to source storage copied to target storage. A copy relationship associates a source storage and target storage pair, wherein writes received at the source storage are transferred to the target storage. A determination is made whether a signal has been received from a system within a receive signal interval. A freeze operation is initiated to cease receiving writes at the source storage from an application in response to determining that the signal has not been received within the receive signal interval. A thaw operation is initiated to continue receiving write operations at the source storage from applications after a lapse of a freeze timeout in response to the freeze operation, wherein after the thaw operation, received writes completed at the source storage are not transferred to the target storage.
