  • Patent number: 7885599
    Abstract: A system, method and computer program product are disclosed for receiving data from a satellite radio network in accordance with an embodiment of the present invention. In accordance with an embodiment of the present invention, a datagram broadcast via a satellite radio network is received utilizing a receiver. The datagram includes broadcast identifier information that identifies a segment of receivers in the satellite radio network to which the datagram is directed. Utilizing the broadcast identifier information, a determination is made as to whether the recipient receiver is a member of the identified segment of receivers to which the datagram is directed. If the recipient receiver is determined to be a member of the identified segment of receivers to which the datagram is directed, then the datagram is processed.

  • Patent number: 7881739
    Abstract: A method and apparatus for adaptively controlling the power level of transmissions from a remote station by determining the velocity of the remote station. A general classification of the velocity of the remote station can be used to selectively implement a closed loop power control scheme. Power level parameters are used to determine velocity. In accordance with a classification of stationary, low speed, or high speed, the closed loop power control is selectively operated. Velocity can be determined by either the base station or the remote station through various methods. One method is the use of power control bits and/or average power to determine level crossings and excursion times.

  • Patent number: 7873330
    Abstract: A transceiver circuit and a method in a wireless communication network are provided, where a signal power level for a signal received at the transceiver circuit is measured and compared to a predefined threshold power level. At least two groups of power amplifiers may be used, where one group is optimized for high efficiency above the predefined threshold power level, and one group is optimized for high efficiency below the predefined threshold power level. The amplifiers may be used to amplify the received signal depending on the signal power level in relation to the predefined power threshold level. The signal may then be filtered by duplex filters and forwarded to a diversity antenna or a main antenna where it is transmitted over an air interface.

  • Patent number: 7865206
    Abstract: A device, system, and method are directed towards determining a suggested characteristic for an event. At least two events are determined. In one embodiment, at least one characteristic is determined for one of the event. A plurality of other characteristics is determined for the other event. The characteristics of the two events may be determined implicitly from communications during the events or from user input. Based on a relationship between the determined characteristics, the suggested characteristic for the event is then determined. In one embodiment, the relationship is defined as a match of characteristics. The event may then be modified based on the suggested characteristic. For example, a suggested member may be invited to join the event, or the event's time, location, or name may be changed. If the other event is current or pending, the event and the other event may be combined.

  • Patent number: 7860526
    Abstract: An integrated circuit configured for outer loop power control uses data transmitted in temporary dedicated channel allocations. A target metric, preferably, target SIR, is adjusted with differing step up and step down increments to converge on a relatively low steady state level of step up and step down target metric adjustments. The initial target SIR and the transient step size for target SIR adjustment is determined in a dynamic way in the outer loop power control for each Temp-DCH allocation of non-real time data.
